Intellectual disability v3.1406 NUP85 Eleanor Williams Gene: nup85 has been classified as Amber List (Moderate Evidence).
Intellectual disability v3.1405 NUP85 Eleanor Williams changed review comment from: PMID: 34170319 - Ravindran et al 2021 report two pedigrees with an MCPH-SCKS phenotype spectrum without SRNS. In the first family, a 9 yo female, with consanguineous parents, is reported to have a missense variant in NUP85 (c.932G > A; p.R311Q). Intrauterine growth restriction was noticed. At birth microcephaly was observed (OFC < 3rd centile, < −3.6 SD) as well as hypotrophy [weight −2.8 SD), length 45 cm (−2.7 SD), both <3rd centile], facial dysmorphism, syndactyly, long and thin fingers, and bilateral pes adductus. She has severe developmental delay with strongly delayed motor milestones and absent speech. Drug-resistant, genetic epilepsy with focal-onset seizures started in the first year of life. She had no clinical, laboratory or radiological findings indicative of kidney dysfunction

In the second family, compound heterozygous missense variants in NUP85 were detected
(c.1109A > G, c.1589 T > C;p.N370S, p.M530T ) in a fetus. MRI of the fetal brain at 24 + 2 GW indicated complete agenesis of the corpus callosum, abnormal sulcation in the left frontal lobe, nodularity of the frontal horn and trigone with focal puckering of the left lateral ventricle.

PMID: 30179222 - Braun et al 2018 - 2 individuals from the 1 of the families reported with steroid-resistant nephrotic syndrome were also reported to have intellectual disability but showed no structural brain defects. The degree of intellectual disability is not stated. They were found to have 2 compound heterozygous alleles (c.405+1G>A and c.1741G>C, p.Ala581Pro), which segregated from the maternal and the paternal side.

White matter disorders and cerebral calcification - narrow panel v1.210 CSF1R Arina Puzriakova Added comment: Comment on mode of inheritance: CSF1R is associated with two relevant disorders both including white matter abnormalities and calcifications. One is an adult-onset rapidly progressive neurodegenerative disorder, associated with monoallelic inheritance (Leukoencephalopathy, diffuse hereditary, with spheroids, OMIM:221820). Conversely, biallelic variants cause a condition with a variable onset but mostly childhood (Brain abnormalities, neurodegeneration, and dysosteosclerosis, OMIM:618476).

Both phenotypes are relevant to this panel and therefore the MOI may be updated from 'Monoallelic' to 'Both mono- and biallelic' at the next GMS review.

Early onset or syndromic epilepsy v2.452 GABRD Helen Lord changed review comment from: Screened the GABRD gene in a cohort of 933 individuals with various childhood-onse epilepsies sequentially referred for diagnostic gene panel testing. The genetic findings were obtained either through targeted epilpesy panels (n=4), WES (n=3) or sanger sequencing (n=3; family 1 patient 6 & 7, family 2 patient 10). Variants classified using the ACMG criteria and badsed on transcript NM_000815.4.
From the original cohort of 933 individuals, presumed pathogenic variants were identified in 3 individuals from 2 unrelated families. Another 7 individuals from 6 families with epilepsy or neurodevelopmental disorders were identified through international collaberations and gene matcher.
The V422I variant occured presumably de novo in two sibs thus one parent must be mosaic.
The T291I variant was detected in an aff mother and her aff twin boys.
The remaining variants M87L, P122A, P257L, L260V & I284T all occured de novo in sporadic patients.
All 7 variants were predicted to be damaging by at least two different prediction tools and had CADD scores above 20. 6 of 7 were absent in gnomAD and our internal dataset. The M87L variant was seen once in gnomAD.
The position of the different variants spans a large part of the delta subunit from the N-terminal end (M87L) to the final transmembrane M4 domain (V442I). Four of the variants (P257L, L260V, I284T & T291I) reside in the M1 and M2 transmembrane domains that are key to forming a functional ion channel. 5 of the 7 variants cause changes to AA residues fully (P122A, P257L & T291I) or highly (L260V & I284T) conserved across human GABAaR subunits.
Functional analysis suggests:
P122A variant results in a 5-fold decrease in the average maximal current amplitude and combined with its increaeed propensity to desensitise - LOF trait.
The 4 variants in the transmembrane domains M1 & M2 (P257L, L260V, I284T, T291I) all resulted in a 3-18 fold increased in current amplitudes - GOF trait.The current amplitude increase in P257L was only 3 fold and this receptor also displayed increased sensitivty to GABA reinforcing the GOF trait.
No functional changes noted for M87L and V422I. As these variants haven't shown any detectable functional changes the 3 individuals carrying these two changes are not included in the phenotypic analysis.

The remaining 7 patients median age of 10 years (ranging from 3-37)/All 6 patients with a GOF variant suffered from generalised epilesy (nost common seizure types atypical absences, generalised myoclonic seizures, tonic seizures and generalised tonic-clonic seizures; occur daily in 4/6 patients and medically refractory in 5/6 patients)and various degrees of learning difficuties or intellectual disability (motor delay in 4/6 with regression or stagnation at seizure onset in at least 2, learning difficulties seen in 6/6 from mild to severe), EEG pattern suggests an underlying cortico-thalmic network tyocial for generalised epilepsys with diffuse spiked and slow waves shown in both humans and animal models~).
The patient with the LOF variant has ASD, normal intelligence and no seizure history.

In summary presumed pathogenic LOF variants were identified in 3 individuals (de novo) and one family (2 twin sibs and mother all aff) with an epilepsy and neurodev disorder.
One GOF variant was identifed (de novo) in a patient with ASD but no seizures.
Two other variants identified in this gene in patients with seizure phenotypes were excluded from phentoypic interpretation as the functional analysis undertaken showed no effect - unclear as to whether these are pathogenic or not.; to: Screened the GABRD gene in a cohort of 933 individuals with various childhood-onset epilepsies sequentially referred for diagnostic gene panel testing.

Primary immunodeficiency or monogenic inflammatory bowel disease v2.481 PI4KA Ivone Leong commented on gene: PI4KA: There is enough evidence to support a gene-disease association. This gene should be rated Green at the next review.

Review by Sophie Hambleton (Newcastle University):

"The immunological abnormalities in PI4KA def are obviously rather variable and a slight side-show to the primary GI and neurologic pathology – however that is a detail that should come out when any putative case is reviewed in detail so I would include this as a “CID with associated or syndromic features” on the same basis as TTC7A"

Added comment: Zornitsa Stark wrote for this gene in Ataxia panel:
"12 individuals from 5 unrelated families reported with a complex neurodevelopmental disorder and bi-allelic variants in this gene. Age range from 21 months to 71 years of age. Main clinical features included axial hypotonia, variably impaired intellectual development with poor or absent speech, and delayed walking (up to 7 years of age) or inability to walk. All had ataxia, often with tremor or dyskinesia, as well as dysarthria associated with cerebellar hypoplasia on brain imaging. Most had optic atrophy, and some had ptosis, chronic progressive external ophthalmoplegia, retinopathy, and strabismus; 1 had early-onset cataracts. The more severely affected individuals had spastic paraplegia and inability to walk.

Functional data including mouse model. "

Added comment: From the literature:
"A heterozygous de novo variant (frameshift) was reported in TAF4 by Kosmicki et al., in a patient with autism.36 The gene has no phenotypic association in OMIM (accessed 12 October 2020). Within this study, we identified two additional de novo LoF variants (splicing and nonsense) in two unrelated patients with dysmorphic features and NDD. TAF4 is highly intolerant to LoF as documented in gnomAD (pLi = 1). Expression of TAF4 varies during development and in the processes of cell differentiation; TAF4 is detected in various regions of the human brain, and it is believed to control the differentiation of human neural progenitor cells having a role in the regulation of neural development and brain function.37 The current data suggests that TAF4 haploinsufficiency leads to NDD in humans."

Details of review:
Aggarwal et al 2020 report a heterozygous nonsense variant in a fetus with ventriculomegaly and Ebstein anomaly resulting in IUFD. Post-mortem found additionally congenital diaphragmatic hernia, common atrium and facial dysmorphism. This nonsense variant is at the same position as a hotspot for missense variants reported in a paediatric cohort (Calpena et al 2019, PMID: 30905399) with overlapping but milder phenotype: half of the 12 children in that cohort had cardiac defects, most had dysmorphic features - hence Aggarwal et al propose that this is a more severe (prenatal) presentation of the same multiple malformation syndrome, caused here by a nonsense rather than missense mutation.

Intellectual disability v3.1395 DHDDS Arina Puzriakova Added comment: Comment on mode of inheritance: MOI should be updated from 'Both mono- and biallelic' to 'Monoallelic' at the next GMS panel update. Monoallelic variants are associated with a neurodevelopmental disorder comprising DD/ID, epilepsy and a variable movement disorder phenotype - >3 unrelated individuals reported in literature. To date, only one individual with biallelic variants and ID has been reported (PMID: 27343064). This patient presented with glycosylation defects but no corroborating cases have been reported since.
As only one patient has been described with biallelic inheritance and this phenotype, MOI should be set to 'Monoallelic' until evidence of additional cases emerges - biallelic variants would still be picked up by the Genomics England pipeline under this MOI.

This gene was added to the DDG2P panel in March 2019 as a amber gene and the reviewer noted the following: "Microcephaly Developmental Delay and Brittle Hair and Nails.

The CARS1 genes was added to the DDG2P panel in March 2019 as an amber gene and the reviewer noted the following: "Microcephaly Developmental Delay and Brittle Hair and Nails. DDG2P Disease confidence: probable. DDG2P mode of pathogenicity/mutation consequence: loss of function. DDG2P mode of inheritance: biallelic."

In Kuo et al (2019) reported the identification of bi-allelic CARS1 variants in four affected individuals from three families with complex syndromes that include microcephaly, developmental delay, and brittle hair and nails.

Case 1: CARS1 c.1138C>T p.(Gln380Ter) and CARS1 c.1022G>A p.(Arg341His) Case 2 and 3 (related): CARS1 c.1076C>T p.(Ser359Leu) and CARS1 c.1199T>A p. (Leu400Gln)
Case 4: Homozygous CARS1 c.2061dup p.(Ser688fs).

In-silico analysis predict that the variants result in a truncated protein or affect a highly conserved amino acid. Immunoblot analysis using CARS antibodies on protein isolated from the patient’s fibroblast confirmed the presence of a stable truncated protein for c.1138C>T nonsense variant, while the amount of full-length CARS protein was significantly reduced for the c.2061dup frameshifting variant. A possible explanation for this result is the extreme 3’ location of the variant which could allow it to escape nonsense mediated decay. Analysis of the CARS protein from Case 4 showed no change in the level of full-length CARS protein. Yeast complementation studies indicate that the p.(Gln380Ter), p. (Leu400Gln) and p.(Ser688fs) variants prevented yeast cell growth, consistent with a loss-of-function effect. Severely reduced cell growth was observed with the p.(Arg341His) and p.(Ser359Leu) variants, aminoacylation assays showed that these variants reduce enzyme activity. These results all support that each variant results in loss of function.

This report confirms that individuals with two loss of function CARS1 variants are involved in multi-system, recessive disorder that includes microcephaly, developmental delay, and brittle hair and nails. Clinical phenotypes that overlap with TTD individuals.

TTD18PV: TARS1 c.826A>G p.(Lys276Glu) and TARS1 c.1912C>T p.(Arg638Ter)
TTD5VI: Homozygous TARS1 c.680T>C (p.Leu227Pro).

Testing of additional individuals with unresolved NPS-TTD by the authors did not identify any further bi-allelic variants suggesting in their cohort of 47, TARS1 variants account for 4% of NPS-TTD cases.

In-silico analysis suggest that missense variants result in amino acid substitutions that are close to the core catalytic domain of the protein which may affect its catalytic activity. Quantitative RT-PCR analysis showed only a slight reduction in total TARS mRNA levels in TTD18PV’s primary fibroblasts, while allelic-specific qRT-PCR analysis showed that 90% of the total TARS mRNA molecules are from the missense p.(Lys276Glu) TARS variant with the remaining only 10% from the c.1912C>T variant allele. Immunoblot analysis of whole-cell extracts from both patient’s fibroblasts revealed an approximate 20% reduction in the total cellular amount of full-length TARS. This is consistent with these missense variants causing protein instability.

Based on a total of 47 NPS-TTD individuals for bi-allelic TARS1 variants, the authors suggest that TARS1 variants account for 4% of NPS-TTD cases.

Intellectual disability v3.1381 CDH15 Arina Puzriakova Classified gene: CDH15 as Green List (high evidence)
Intellectual disability v3.1381 CDH15 Arina Puzriakova Added comment: Comment on list classification: Gene should be demoted to Red as there is limited evidence supporting this gene-disease association. The only cases reported to date with SNVs were discovered by targeted sequencing of CDH15. Clinical information was limited, describing only mild ID in some cases. There are also multiple benign LOF variants in population databases. Asymptomatic carriers lead authors to suggest incomplete penetrance but all identified variants are in gnomAD so are unlikely to be causal.

I would be inclined to include it on the paediatric panel, as they are outlining the spasticity as a feature of ODDD, rather than a separate clinical entity. ODDD would be a paediatric-age diagnosis to make and the fact that it is clinically recognisable could aid in interpretation of variants of uncertain significance"

Both children had generalised cutaneous hypopigmentation without ocular involvement, delayed myelination and motor development, and organomegaly. Biopsies showed that both probands had cytoplasmic inclusions, characteristic of those seen in lysosomal-storage disorders. Human phenotypes were recapitulated by a mouse model harbouring the knock-in Clcn7 variant.

Intracerebral calcification disorders v1.30 AP1S2 Arina Puzriakova Publications for gene: AP1S2 were set to 17617514 - identification of AP1S2 variants in a large 4-generation French family, and a Scottish family, marked calcifications of the basal ganglia were reported in affected individuals in both families; 18428203 - an additional two families reported "Studying four patients in two unrelated families in which AP1S2 nonsense and splicesite
mutations segregated, we found that affected individuals presented, in addition to previously described features,
with elevated protein levels in cerebrospinal fluid (CSF). Moreover, computed tomography scans demonstrated that
the basal ganglia calcifications associated with AP1S2 mutations appeared during childhood and might be
progressive. Based on these observations, we propose that AP1S2 mutations are responsible for a clinically
recognizable XLMR and autism syndrome associating hypotonia, delayed walking, speech delay, aggressive
behavior, brain calcifications, and elevated CSF protein levels."

Fetal anomalies v1.729 AP1S2 Arina Puzriakova Added comment: Comment on mode of inheritance: Review of literature did not reveal any confirmed affected females. Female carriers of AP1S2 variants are phenotypically normal and have mostly shown random X-inactivation. Huo et al., 2019 (PMID: 30714330) state that they identified a female patient (I-1) but this individual was not available for genetic testing and so it is unclear whether they harboured a variant on a one or both alleles.

As no confirmed female cases have been reported and the allelic requirement remains elusive, the MOI should be set to the default XL (i.e. monoallelic in females may cause disease) as this will ensure that both mono and biallelic variants are picked up in females by the pipeline.

Green review from Rhiannon Mellis (Great Ormond Street Hospital) on the Rare multisystem ciliopathy disorders panel (ID: 150):

"The same group who reported the first individual with a ciliopathy phenotype (Adly et al 2014) now report two further unrelated fetal cases (Alsahan 2020, Monies et al 2019) with OFD/ciliopathy phenotype:

- One had polyhydramnios, hydrocephaly with enlarged biparietal diameter and dilated lateral ventricles, single nostril, anophthalmia, short long bones and echogenic lungs
- The other had holoprosencephaly, cyclops, cleft lip, ventricular septal defect, agenesis of corpus callosum, and club feet

- There are also two sib pairs (one Finnish, one Pakistani) reported by Hietamaki et al 2020 with TBC1D32 variants and a variable phenotype of pituitary hypoplasia +/- other midline defects, hydrocephalus, short limbs, polydactyly

Retinal disorders v2.220 ARL3 Ivone Leong Added comment: Comment on publications: PMID:30269812 describes 2 unrelated consanguineous families (Saudi and Pakistani). Both have phenotype resembling Joubert syndrome (night blindness, rod-cone dystrophy, mild dysmorphic features, hypotonia (only in 1 family), ataxia, cerebellar vernis hypoplasia). Both are homozygous missense for the same amino acid residue (R149C, R149H). The authors performed some in vitro functional analysis.

PMID:16565502 describes a knockout mouse model of Arl3. The homozygous knockouts developed ciliary disease affecting kidney, biliary tract, pancreas and retina. However, there was no mention of a brain phenotype.

PMID:31743939 describes 2 large consanguineous Pakastani families with the same homozygous variant (Arg99Ile). There are 8 affected individuals in total and 7/8 had cone-rod dystrophy and no features of Joubert syndrome.

PMID:33748123 describes a Chinese family. Proband is compound het (c.91A>G, p.T31A; c.353G>T, p.C118F) and has retinal dystrophy. Heterozygous father has late onset and mild rode-cone dystrophy. Mother and sister (het) are normal. All family members did not have any other phenotypes.

PMID:26964041 describes a family with affected mother, son and daughter with retinitis pigmentosa. Affected patients were heterozygosity for Y90C. The mother's parents do not have the variant suggesting that it is a de novo event in the mother. No functional studies of the variant were performed.

PMID:30932721 reports a case where a patient has a de novo Y90C variant and has RP.

Paediatric or syndromic cardiomyopathy v1.57 GSN Ivone Leong Added comment: Comment on list classification: New gene added by Dmitrijs Rots (RadboudUMC). This gene is associated with a phenotype in OMIM and Gene2Phenotype.

PMID: 26339870 found that 12/227 patients had cardiomyopathy and previous case reports and publications show that cardiomyopathy is only present in some cases and the age of diagnosis (or when pacemakers were implants into patients) is >50 years. Cardiomyopathy does not appear to be a presenting feature.

Therefore, this gene has been given an Amber rating.

Fast track form submitted. Note from Prof Kinsler:
We have noticed that BRAF is not included on this panel. As a key player in mosaic diseases of various types this was an error somehow in the preparation of the original list. Without it's inclusion on the panel various conditions cannot be properly tested for. For example 7% of Congenital Melanocytic Naevus syndrome are caused by BRAF mosaicism and approximately 5% of Arteriovenous Malformations.

Fetal anomalies v1.727 BMPR1B Arina Puzriakova changed review comment from: Comment on mode of inheritance: Biallelic variants lead to the Demirhan type of acromesomelic dysplasia (MIM# 609441) which is pertinent to this panel. Monoallelic variants cause brachydactyly (MIM# 616849 and MIM# 112600) with dysplasia of only a single or few phalanges which would be difficult to diagnose prenatally. For this reason the MOI should remain as biallelic only on this panel.; to: Comment on mode of inheritance: Biallelic variants lead to the Demirhan type of acromesomelic dysplasia (MIM# 609441) which is pertinent to this panel.

Intellectual disability v3.1362 RAD51 Arina Puzriakova Classified gene: RAD51 as Amber List (moderate evidence)
Intellectual disability v3.1362 RAD51 Arina Puzriakova Added comment: Comment on list classification: Intellectual disability has been reported in 2/3 individuals with RAD51-associated FA (third patient with mild early DD). However, a syndromic presentation prior to this is expected. Potential for VUSs in pure ID cohort, although there is an allied chromosome breakage test. Upgrading from Red to Amber - which also reflects the rating of other FA genes associated with ID.

Fetal anomalies v1.725 BHLHA9 Eleanor Williams Added comment: Comment on mode of inheritance: Biallelic single nucleotide variants in this gene are associated with Syndactyly, mesoaxial synostotic, with phalangeal reduction (OMIM:609432). Monoallelic duplications of the whole gene are associated with split hand/foot malformations, but it is not clear if they are inherited in an Mendelian manner (see review on the Limb disorders panel https://panelapp.genomicsengland.co.uk/panels/384/gene/BHLHA9/)

Therefore the recommendation is that the mode of inheritance should be biallelic only for this gene, with region being eventually represented by a separate entity.

(2021) report 6 probands who presented with craniofacial (5/6), vertebral (5/6), neurological (6/6), visual (4/6), cardiac (3/6), auditory (3/6), and connective tissue abnormalities (3/6). They found de novo and inherited variants in GDF11. gdf11 mutant zebrafish showed craniofacial abnormalities and body segmentation defects that matched some patient phenotypes. Expression of the patients’ variants in the fly showed that one nonsense variant in GDF11 is a severe loss-of-function (LOF) allele whereas the missense variants are partial LOF variants.

PMID 31215115: In 5 affected members over 3 generations of a family segregating vertebral hypersegmentation and orofacial anomalies, Cox et al. (2019) identified heterozygosity for a missense mutation in the GDF11 gene (R298Q) that was not found in unaffected family members or in public variant databases. Functional analysis demonstrated that the R298Q substitution prevents cleavage to the active form of the protein, resulting in loss of function.

Added comment: Dworschak et al. (2021) via WES reported 10 patients from 7 families with biallelic (n=7) or de novo (n=3) PLXNA1 variants. Shared phenotypic features include global developmental delay (9/10), brain anomalies (6/10), and eye anomalies (7/10). Seizures were predominantly reported in patients with monoallelic variants. Zebrafish studies showed an embryonic role of plxna1a in the development of the central nervous system and the eye. Biallelic variants in the extracellular Plexin-A1 domains lead to impaired dimerization or lack of receptor molecules, whereas monoallelic variants in the intracellular Plexin-A1 domains might impair downstream signaling through a dominant-negative effect.

Added comment: No OMIM human disease association. Gene encodes a presynaptic protein Munc13-2 highly expressed in the brain (predominantly cerebral cortex).

Variant interpretation data in human epilepsy cohort somewhat conflicting and restricted to a single study. Wang et al, Brain, 2021 - trio-based whole-exome sequencing identified UNC13B in 12 individuals affected by partial epilepsy and/or febrile seizures from 8 unrelated families. Identified:
x1 de novo nonsense variant, absent in gnomad, damaging in silicos
x1 de novo splice site, absent in gnomad, damaging in silicos
x1 splice site variant present in unaffected mother (low frequency in gnomad)
x2 compound het in one individual - more severe phenotype postulated (x1 variant present in contro cohortl, the other variant present in low frequency in gnomad)
x1 missense variant - in Han Chinese major depressive disorders study, not in gnomad
x1 missense variant - highly conserved residue, not in gnomad
x2 other missense variant - highly conserved residue, low frequency in gnomad
Latter 4 missense variants cosegregated with affected individuals in the families

In Drosophila, seizure rate and duration were increased by Unc13b knockdown compared to wild-type flies, but these effects were less pronounced than in sodium voltage-gated channel alpha subunit 1 (Scn1a) knockdown Drosophila

De novo UNC13B variants previously reported in bipolar disorder and autism spectrum disorder

Added comment: WNT9B plays a key role in the development of the mammalian urogenital system. It is essential for the induction of mesonephric and metanephric tubules, the regulation of renal tubule morphogenesis, and the regulation of renal progenitor cell expansion and differentiation. WNT9B−/− mice have renal agenesis/hypoplasia and reproductive tract abnormalities.

Lemire et al. (2021) report 4 individuals from 2 unrelated consanguineous families with bilateral renal agenesis/hypoplasia/dysplasia and homozygous variants in WNT9B. The proband from Family 1 had bilateral renal cystic dysplasia and chronic kidney disease, with 2 deceased siblings with bilateral renal hypoplasia/agenesis. The 3 affected family members were homozygous for a Gly317Arg missense variant in WNT9B. Proband from Family 2 had renal hypoplasia/dysplasia, chronic kidney disease, and was homozygous for a Pro5Alafs*52 nonsense variant in WNT9B. The proband's unaffected brother is also homozygous for the nonsense variant in WNT9B, suggesting nonpenetrance.

Clinical features include: tone abnormalities, global developmental delay, facial dysmorphism, autism spectrum disorder, and seizures. Additionally, there were a variety of other findings in the skeletal, renal, ocular, and cardiac systems. The missense alterations all occurred within a highly conserved RecA-like domain of the protein, and are located within or proximal to the DEAD box sequence.

Added comment: Reinstein et al. (2018) used WES in a large consanguineous Israeli Arab kindred consisting of 16 patients affected with the neurogenic type of arthrogryposis multiplex congenita. They identified a homozygous missense (V98E) mutation in ERGIC1 gene, which segregated with the disorder in the kindred, and was not found in the ExAC database or in 212 ethnically matched controls. Functional studies of the variant and studies of patient cells were not performed. ERGIC1 encodes a cycling membrane protein which has a possible role in transport between endoplasmic reticulum and Golgi.

Marconi et al (2021) used genome sequencing in a consanguineous family with 2 affected siblings presenting congenital arthrogryposis and some facial dysmorphism. They identified a homozygous 22.6 Kb deletion encompassing the promoter and first exon of ERGIC1. mRNA quantification showed the complete absence of ERGIC1 expression in the two affected siblings and a decrease in heterozygous parents.

Added comment: 13q12.3 microdeletion syndrome is a rare cause of syndromic ID. Previous studies identified four genes within the ~300 Kb minimal critical region including two candidate protein coding genes: KATNAL1 and HMGB1.

Uguen et al. (2021) report 6 patients with LOF variants involving HMGB1 with features similar to 13q12.3 microdeletion syndrome (i.e. developmental delay, language delay, microcephaly, obesity and dysmorphic features). In silico analyses suggest that HMGB1 is likely to be intolerant to LOF, and previous in vitro data are in line with the role of HMGB1 in neurodevelopment. They suggest that haploinsufficiency of the HMGB1 gene may play a critical role in the pathogenesis of the 13q12.3 microdeletion syndrome.

PMID: 21315357 - Holleboom et al 2011 - report 3 siblings (age 17, 12 and 3 years) in a family with HDL deficency. The 17-year-old was referred for renal pathology compatible with a metabolic disorder, including FLD. Corneal opacification and proteinuria were observed in all three and they were found to be homozygous for a missense variant in LCAT which disrupted the second disulfide. LCAT protein and activity were undetectable in the patients' plasma. The parents and an unaffected brother were heterozygous for the variant.

PMID: 30201532 - Hanna et al 2018 - report a 29-year-old female who initially presented with discomfort, photophobia, and decreased vision in both eyes. Bilateral corneal clouding, severely reduced HDL cholesterol, and proteinuria were noted. Two heterozygous mutations of the LCAT gene were identified: c.321C>A (p.Tyr107 *) and c.1034C>T (p.Thr345Met)

PMID: 29535099 - Morales et al 2018 - report 44-year-old woman diagnosed with corneal dystrophy and anaemia. Analysis showed proteinuria between 1 and 2 g/day. A missense homozygous variant in the LCAT gene c.368G>C (p (R123p)) was identified.

PMID: 22108153 - Roshan et al 2011 - report a 50-year-old man with uncontrolled hypertension, hemolytic anemia, and renal insufficiency. He had a long history of proteinuria (3+ for at least 30 years). He was found to have diffuse marked corneal opacification. Sequencing the LCAT gene showed a homozygous missense mutation. His parents were first cousins.


Cases presenting with proteinuria with a LCAT deficiency diagnosis but no molecular analyses:

PMID: 28508023 - Balwani et al 2016 - a patient with nephrotic syndrome, which renal biopsy revealed classic features of LCAT deficiency. There was no obvious family history and the patient was without any corneal deposits and normal HDL-C levels. NOTE NO MOLECULAR DIAGNOSIS.

Monogenic hearing loss v2.187 USP48 Eleanor Williams edited their review of gene: USP48: Added comment: PMID: 34059922 - Bassani et al 2021 - 3 cases reported with variants in USP48 and non syndromic hearing loss. They first analysed 4-generation Italian family with 6 individuals with hearing loss. The only rare variant segregating with the disease was a missense variant in USP48 (NM_032234.7:c.1216G > A, NP_115612.4:p.(Gly406Arg)). The variant is present in GnomAD v2.1.1 with a minor allele frequency (MAF) of 6.7 × 10−5 (17 allele out of 251 304 with no homozygotes). They also observed one hearing individual in the family who was heterozygous for the variant, suggesting incomplete penetrance.
In a Dutch family the found by exome sequencing a missense variant in USP48 (NM_032236.7:c.2215_2216delinsTT, NP_115612.4:p.(Thr739Leu)). The probands mother and uncle were also affected by no sequence data was available for analysis.
In a French family a proband is reported with right profound sensorineural hearing impairment (at 12 months), but normal left hearing (at 6 years old). The patient is heterozygote for a de novo splice variant in USP48 (NM_032236.7:c.3058 + 2 T > C, NP_115612.4:p.?;) which is not found in GnomAD and is predicted to result in a frameshift resulting in either NMD or a truncated protein.
In functional experiments they showed that the two missense variants found in the Italian and Dutch families, and a shortened protein as predicted for the variant found in the French variant, showed an impaired ability to cleave tetra-ubiquitin into tri-, di- and mono-ubiquitin. Using immunohistology, they show that the human USP48 protein is present in fetal inner ear specimens.

PMID: 9536092, reported one patient with homozygous G56S. The patient was the only member of the family to be affected by disease (proximal muscle weakness in the first decade of life). The variant was not found in 200 controls. The patient's skeletal muscle biopsy looked normal and expression of dystrophin, sarcoglycans and caveolin-3 was normal. This variant was later reclassified as a VUS as PMID:11251997 identified 2 Brazilian patients with LGMD with heterozygous G55S. Both patients had onset in adulthood, calf hypertrophy, elevated creatine kinase, and difficulty walking. Muscle protein analyses from both patients were normal. Screening 200 normal controls showed 4 controls also had this variant.
In OMIM: "Hamosh (2018) found that the G55S variant was present in heterozygous state in 3,142 of 277,064 alleles and in 184 homozygotes in the gnomAD database (January 24, 2018), calling into question the pathogenicity of the variant."

PMID: 12666119, reported an Italian patient with severe rippling muscle disease (A92T) who was AR. Actually A93T.

PMID: 15668980, the same authors of PMID: 12666119 reported 1 family with 2 affected sibs who have AR rippling muscle disease (same variant as above A92T). Unaffected parents were both heterozygous for the variant. The authors note that the parents were not known to be consanguineous but they are from the same small village in Germany. The authors also did a haplotype analysis and showed that this variant arose separately from the Italian case, suggesting that A92 might be a mutation hot spot. According to ClinVar, this variant has conflicting interpretations of pathogenicity (https://www.ncbi.nlm.nih.gov/clinvar/variation/8285/).

PMID: 16730439, reports on 1 patient (AR) with mild proximal muscle weakness of the lower limbs. No other family members were available for further analysis. Patient is homozygous for a splice variant (IVS1+2T>C).

While there are cases of biallelic variants causing disease there are currently no new cases reporting of this (newest report was in 2006). There is currently not enough evidence to support biallelic cause of disease, I suggest changing the MOI to Monoallelic until more evidence is available.; Changed publications to: 15668980, 12666119, 9536092, 11251997, 16730439; Changed mode of inheritance: MONOALLELIC, autosomal or pseudoautosomal, imprinted status unknown

Early onset or syndromic epilepsy v2.434 MED12 Eleanor Williams changed review comment from: Review of mode of inheritance shows that although in some families only males were affected, in 5 cases females with seizures as part of the phenotype were reported who had MED12 variants therefore a mode of inheritance of X-LINKED: hemizygous mutation in males, monoallelic mutations in females appears correct.

Reports of males only affected:
PMID: 17369503 - Schwartz et al 2007 - report 2 kindreds with males (7 total) affected with Lujan-Fryns syndrome and variants in MED12. Seizures were noted in 1 individual from 1 kindred.

PMID: 23395478 - Vulto-van Silfhout et al 2013 - report 3 unrelated cases with males affected by Ohdo syndrome MKB type. In 2 families 2 males were affected, in the third 1 male. In all, missense changes in MED12 were detected. In family 2 a second segregating missense variant in the ATRX gene (linked to ATRX syndrome) but further investigation did not support a ATRX syndrome diagnosis. Intellectual disability was noted (1 mild, 1 moderate, 2 severe, 1 severity not noted) in all 5 individuals. Seizures were noted in 1.

PMID: 32715471 - Rubin et al 2020 - report 1 family with three male siblings of with intellectual disability and characteristic facial and distal extremity anomalies with a novel missense variant in MED12. The diagnosis most closely matched Ohdo syndrome. Seizures are not reported.

PMID: 17334363 - Risheg et al 2007 - report 6 families in with Opitz-Kaveggia syndrome (also known as FG syndrome) in with the same 2881C>T variant identified in MED12. Two of the families are stated to be from different ethnic groups. In all families only males were affected. Intellectual disability was present in all affected males (4 families) who survived long enough for developmental or cognitive assessment. Seizures were noted in 3 of the families (4/7 individuals). Marked skewed X inactivation was noted in female carriers in 3 families, moderate skewing in 1 family and absence of skewing in two families.

Reports with females affected:

PMID: 33244165 - Polla et al 2021 - report on assembled clinical and genetic data of 18 females with de novo variants in MED12. 11/18 have severe intellectual disability. Seizures were noted in 5.
Analysis of X-inactivation status showed extreme skewing (>95%) in 10 indivduals, skewing (85%) in 1 individual and it was random XCI in 6 (3 with protein truncating variants, 3 with missense). The androgen receptor alleles were non-informative for 1 person.

PMID: 34079076 - Riccardi et al 2021 - report an additional 4 female patients that carry de novo missense variants in MED12. All four patients had an intellectual disability, though it was severe only in one case. No seizures were noted.; to: Review of mode of inheritance shows that although in some families only males were affected, in 5 cases females with seizures as part of the phenotype were reported who had MED12 variants therefore a mode of inheritance of X-LINKED: hemizygous mutation in males, monoallelic mutations in females appears correct although consideration should be given to the carrier implications for the predominantly male-only phenotypes associated with this gene.

Reports of males only affected:
PMID: 17369503 - Schwartz et al 2007 - report 2 kindreds with males (7 total) affected with Lujan-Fryns syndrome and variants in MED12. Seizures were noted in 1 individual from 1 kindred.

PMID: 23395478 - Vulto-van Silfhout et al 2013 - report 3 unrelated cases with males affected by Ohdo syndrome MKB type. In 2 families 2 males were affected, in the third 1 male. In all, missense changes in MED12 were detected. In family 2 a second segregating missense variant in the ATRX gene (linked to ATRX syndrome) but further investigation did not support a ATRX syndrome diagnosis. Intellectual disability was noted (1 mild, 1 moderate, 2 severe, 1 severity not noted) in all 5 individuals. Seizures were noted in 1.

PMID: 32715471 - Rubin et al 2020 - report 1 family with three male siblings of with intellectual disability and characteristic facial and distal extremity anomalies with a novel missense variant in MED12. The diagnosis most closely matched Ohdo syndrome. Seizures are not reported.

PMID: 17334363 - Risheg et al 2007 - report 6 families in with Opitz-Kaveggia syndrome (also known as FG syndrome) in with the same 2881C>T variant identified in MED12. Two of the families are stated to be from different ethnic groups. In all families only males were affected. Intellectual disability was present in all affected males (4 families) who survived long enough for developmental or cognitive assessment. Seizures were noted in 3 of the families (4/7 individuals). Marked skewed X inactivation was noted in female carriers in 3 families, moderate skewing in 1 family and absence of skewing in two families.

Reports with females affected:

PMID: 33244165 - Polla et al 2021 - report on assembled clinical and genetic data of 18 females with de novo variants in MED12. 11/18 have severe intellectual disability. Seizures were noted in 5.
Analysis of X-inactivation status showed extreme skewing (>95%) in 10 indivduals, skewing (85%) in 1 individual and it was random XCI in 6 (3 with protein truncating variants, 3 with missense). The androgen receptor alleles were non-informative for 1 person.

PMID: 34079076 - Riccardi et al 2021 - report an additional 4 female patients that carry de novo missense variants in MED12. All four patients had an intellectual disability, though it was severe only in one case. No seizures were noted.

Fetal anomalies v1.720 MED12 Eleanor Williams changed review comment from: Comment on mode of inheritance: Variants in this gene have also been reported in females with Hardikar syndrome (Li et al 2021, PMID: 33244166). The phenotype includes facial clefting, pigmentary retinopathy, biliary anomalies, hydronephrosis, and intestinal malrotation.

In addition Polla et al 2021 (PMID: 33244165) and Riccardi et al 2021 (PMID: 34079076) report 22 females in total with de novo variants in MED12. Some physical features such as syndactyly (10/22) and anteriorly placed anus (4/22) are noted. 12/22 have severe intellectual disability.

X-linked hemizygous mutation in males, monoallelic mutations in females is the appropriate mode of inheritance for Hardikar syndrome but there are carrier implications for the predominantly male-only phenotypes associated with this gene (e.g. Lujan-Fryns syndrome, Ohdo syndrome, X-linked and Opitz-Kaveggia syndrome) in female cases. ; to: Comment on mode of inheritance: Variants in this gene have also been reported in females with Hardikar syndrome (Li et al 2021, PMID: 33244166).

Arthrogryposis v3.122 MED12 Eleanor Williams reviewed gene: MED12: Rating: ; Mode of pathogenicity: None; Publications: ; Phenotypes: ; Mode of inheritance: X-LINKED: hemizygous mutation in males, biallelic mutations in females
Early onset or syndromic epilepsy v2.431 MED12 Eleanor Williams changed review comment from: Review of mode of inheritance shows that although in some families only males were affected, females were also reported in 5 cases seizures with MED12 variants therefore a mode of inheritance of X-LINKED: hemizygous mutation in males, monoallelic mutations in females appears correct.

Reports of males only affected:
PMID: 17369503 - Schwartz et al 2007 - report 2 kindreds with males (7 total) affected with Lujan-Fryns syndrome and variants in MED12. Seizures were noted in 1 individual from 1 kindred.

PMID: 23395478 - Vulto-van Silfhout et al 2013 - report 3 unrelated cases with males affected by Ohdo syndrome MKB type. In 2 families 2 males were affected, in the third 1 male. In all, missense changes in MED12 were detected. In family 2 a second segregating missense variant in the ATRX gene (linked to ATRX syndrome) but further investigation did not support a ATRX syndrome diagnosis. Intellectual disability was noted (1 mild, 1 moderate, 2 severe, 1 severity not noted) in all 5 individuals. Seizures were noted in 1.

PMID: 32715471 - Rubin et al 2020 - report 1 family with three male siblings of with intellectual disability and characteristic facial and distal extremity anomalies with a novel missense variant in MED12. The diagnosis most closely matched Ohdo syndrome. Seizures are not reported.

Two of the families are stated to be from different ethnic groups. In all families only males were affected. Intellectual disability was present in all affected males (4 families) who survived long enough for developmental or cognitive assessment. Seizures were noted in 3 of the families (4/7 individuals). Marked skewed X inactivation was noted in female carriers in 3 families, moderate skewing in 1 family and absence of skewing in two families.

Reports with females affected:

PMID: 33244165 - Polla et al 2021 - report on assembled clinical and genetic data of 18 females with de novo variants in MED12. 11/18 have severe intellectual disability. Seizures were noted in 5.
Analysis of X-inactivation status showed extreme skewing (>95%) in 10 indivduals, skewing (85%) in 1 individual and it was random XCI in 6 (3 with protein truncating variants, 3 with missense). The androgen receptor alleles were non-informative for 1 person.

PMID: 34079076 - Riccardi et al 2021 - report an additional 4 female patients that carry de novo missense variants in MED12. All four patients had an intellectual disability, though it was severe only in one case. No seizures were noted.; to: Review of mode of inheritance shows that although in some families only males were affected, in 5 cases females with seizures as part of the phenotype were reported who had MED12 variants therefore a mode of inheritance of X-LINKED: hemizygous mutation in males, monoallelic mutations in females appears correct.

Even though this likely represents a founder effect in this population, an additional patient from Asian origin has been identified with a distinct homozygous variant (c.448G>C), corroborating pertinence of GTF2E2 variants in trichothiodystrophy. Furthermore, studies on primary fibroblasts of patients harbouring the founder variant demonstrated a reduction in the cellular levels of both subunits of the transcription initiation factor TFIIE.

There is a lack of single nucleotide variants reported in this gene with relevance to retinal disorders and and therefore adding this gene as green risks reporting irrelevant SNVs.; Changed rating: AMBER
Retinal disorders v2.216 IRX5 Eleanor Williams changed review comment from: Associated with Hamamy syndrome #611174 (AR) in OMIM. Hamamy syndrome is characterised by craniofacial dysmorphism, hearing loss, skeletal anomalies, microcytic hypochromic anemia and congenital heart defects. Severe myopia has also been reported. Homozygous missense variants in IRX5 were reported in 2 families with this condition (PMID: 22581230;17230486)

Duplication of gene
-------------------
PMID: 33891002 - Kohl et al 2021 - report 3 unrelated families with duplications of a region covering the genes IRX5 and IRX6 completely, and the proximal exons of MMP2 and cone dystrophy. They propose that overexpression of IRX5 and IRX6 may be the cause of the disease, and this is supported by expression analysis in patient-derived fibroblasts and zebrafish experiments.

Initial family is a large 5 generation German family with 14 members with autosomal dominant cone dystrophy in which a 600kb duplicated region covering IRX5/IRX6 and part of MMP2 was identified. 2 additional families of Chinese and Dutch descent with copy number gains of ~700 and ~850 kb, covering the same region were then identified. The smallest region of overlap is 608kb. In addition another family of German decent is reported with adCD and the same duplication as the first German family. It is not known if they are distantly related. Segregation analysis on available members of all families showed the duplication in affected members and not in unaffected.

They find that IRX5, IRX6 and MMP2 are expressed in human adult retina. Several lincRNA within the locus are also expressed. In patient derived fibroblasts IRX5 and IRX6 showed increased expression levels. Over expression of IRX5 and IRX6 results in impaired visual performance in zebrafish larvae.

Added comment: Zorntiza Stark reviewed this gene on the Clefting panel. Li et al 2021 (PMID: 33244166) report 7 females with Hardikar syndrome each of whom have had a nonsense or frameshift MED12 variant identified by exome sequencing. All five tested patients showed evidence of skewed x chromosome inactivation. 5 of the patients are reported to have a retinal phenotype (retinal rarefaction, pigmentary retinopathy, cat’s paw retinal pigmentation).

Hardikar syndrome is noted for the preserved neurodevelopment in patients unlike the other disorders associated with this gene.

Retinal disorders v2.213 SPTLC2 Ivone Leong Added comment: Comment on list classification: New gene added by Dmitrijs Rots (RadboudUMC). This gene is associated with a phenotype in OMIM and Gene2Phenotype.

PMID: 31509666 reported on 2 unrelated families (family 1 and 2) and 3 unrelated individuals (patients 1, 2 and 3) who have HSAN1 and have variants in SPTLC1 (2 families and patient 1 have the same heterozygous variant C133Y, and patient 2 and 3 have C133W, also heterozygous). Those with the C133Y variant have HSAN1 and macular telangiectasia type 2 and those with C133W variant only have HSAN1 and no eye phenotype. The authors note that patients with C133W both patients were under the age of 50 and had been treated with serine supplementation.

Affected members of family 3 was diagnosed with HSAN1C and were heterozygous for S384F in SPTLC2 and macular telangiectasia type 2.

As there is only one case, there is not enough evidence to support a gene-disease association. This gene has been given a Red rating.

PMID: 31509666 reported on 2 unrelated families (family 1 and 2) and 3 unrelated individuals (patients 1, 2 and 3) who have HSAN1 and have variants in SPTLC1 (2 families and patient 1 have the same heterozygous variant C133Y, and patient 2 and 3 have C133W, also heterozygous).

Affected members of family 3 was diagnosed with HSAN1C and were heterozygous for S384F in SPTLC2 and macular telangiectasia type 2.

While there appears to be a link between this gene and macular telangiectasia type 2, all affected families/individuals have the same variant. Therefore, there is currently enough evidence to support a gene-disease association. This gene has been given an Amber rating until more information is available.

Added comment: Goodman et al., 2021 (PMID: 34314705) reported on 15 unrelated individuals with different variants in this gene (14 de novo, 1 mosaic in mother; 12 SNVs, 3 in-frame deletions, 1 deletion-insertion). All had GDD and all those who were assessed also had ID (9/9), ranging from mild to severe. ID also suspected but not investigated in another 3 cases. 6 had seizures starting between 1 and 2.5 years of age. 5 individuals had microcephaly (HC ranging -2.77 to -4.53 SD). Other less common features were also observed such as variable brain, gastrointestinal and ophthalmologic abnormalities.

Notably 6 individuals had additional SNVs/CNVs of uncertain significance, some of which include known ID genes (e.g. SETBP1, CUX2, ARMC9, PDE4D), but were discounted due to lack of explanation of the overall patient phenotype.

Some functional studies conducted in Drosophila demonstrated that patient-associated variants caused neurodevelopmental defects that were dosage and location (of variant within protein) dependent.

Review for gene: LRRK1 was set to GREEN
Added comment: A detailed phenotypic picture of Osteosclerotic metaphyseal dysplasia (OSMD) in patients with LRRK1 variants can be seen in table 1 of Howaldt et al (2020).

Lida et al (2016) identified homozygous deletion that is predicted to result in elongation of protein (p.E1980Afs*66) in a child with OSMD. Child was born to consanguineous parents, both heterozygous for variant.

Guo et al (2017) identified a family with OSMD. Healthy, non-consanguineous parents have two children with OSMD that are homozygous for 1bp insertion in LRRK1 that is predicted to result in a frame-shift and produce an elongated protein (p.A1991Gfs*31) without nonsense-mediated mRNA decay. A similar effect seen in Lida et al (2016).

Howaldt et al (2020) shows a patient with a homozygous splice site mutation resulting in near complete skipping of exon 3 in cDNA leading to a frameshift (p.Ala34Profs*33). The variant segregated with disorder in the family with parents being heterozygous for the variant and clinically unaffected.

Miryounesi et al (2020) identified a patient with suspected OSMD from healthy, consanguineous parents. Patient is homozygous for stop gain mutation (c.2785G > T, p.E929X) in LRRK1. Parents are heterozygous for the variant.

Homozygous nonsense variant in LRRK1 also identified in an individual recruited to the 100,000 genomes project for skeletal dysplasia, Osteosclerotic metaphyseal dysplasia is considered a good fit for phenotype.

LRRK1 gene should be included in the skeletal dysplasia panel as a green gene at the next GMS panel update.

PMID: 33154040 describes another case. "3.5-yr-old Caucasian/Peruvian/Native American boy with microcephaly, severe global developmental delay, and multiple congenital abnormalities. At birth he was documented to have a small ventricular septal defect (which was closed by 3 wk), a patent foramen ovale, rhizomelic shortening of extremities on clinical examination, pectus carinatum, and underdeveloped genitalia including severe penoscrotal hypospadias and cryptorchidism." OFC at birth was just above 10th centile, at 3.5 yr OFC is below 3rd centile but no actual measurements were given. Microarrays identified a 95-kb loss at 12q23.2 including exons 1–4 of the NUP37 gene and exons 1–9 of the PARPBP gene, which were deemed nondiagnostic (neither parents had this deletion). A heterozygous variant was also found in HSPG2 (c.9893 C > T, p. Pro3298Leu). Biallelic variants in this gene is associated with skeletal disorders that did not fit the patient's phenotype and as the patient is heterozygous for a variant in HSPG2 it was deemed that this variant was not causative. WGS identified a de novo splice variant in ARCN1. mRNA studies showed that the variant caused retention of part of an intron in the transcript. The authors deemed the ARCN1 variant as the causative variant in this patient.

Intellectual disability v3.1292 AP1G1 Arina Puzriakova Added comment: Comment on list classification: New gene added by Zornitza Stark. Usmani et al., 2021 (PMID: 34102099) identified 9 families with heterozygous and 2 families with homozygous variants in this gene. All individuals (12) had GDD and ID of various severity (mild to severe), except one patient who died at 22 days. Other features include hypotonia (9/10), seizures (6/10) and spasticity (4/10). Some supportive functional data included.

There is sufficient evidence to promote this gene to Green at the next GMS panel update, with 'monoallelic' MOI. Biallelic cases would still be picked up by the Genomics England pipeline - but this may be reviewed if additional cases are discovered.

Added comment: Eleven affected patients were identified. All had heterozygous missense variants involving exon 9 of RHOBTB2, confirmed as de novo in 9 cases. All had a complex motor phenotype, including at least 2 different kinds of movement disorder, e.g., ataxia and dystonia. Many patients demonstrated several features fulfilling the criteria for AHC: 10 patients had a movement disorder including paroxysmal elements, and 8 experienced hemiplegic episodes. In contrast to classic AHC, commonly caused by mutations in ATP1A3, these events were reported later only in RHOBTB2 mutation-positive patients from 20 months of age. All had ID, and many had seizures, so this represents an expansion of the phenotype rather than a distinct disorder.

Publications for gene: IFIH1 were set to 34185153
Phenotypes for gene: IFIH1 were set to Inflammatory Bowel Disease
Review for gene: IFIH1 was set to GREEN
Added comment: IFIH1 encodes MDA5, a key cystolic sensor for viral nucleic acids. Rare, likely loss-of-functions IFIH1 variants identified in eight independent probands with Very Early Onset Inflammatory Bowel Disease (VEOIBD) from a combined cohort of 42 children. IFIH1 variants were significantly enriched in children with VEOIBD as compared to controls (p=0.007).
In one case of neonatal-onset IBD, a homozygous truncating variant was identified. There were seven carriers of LoF variants identified (range of onset 6 months to 6 years of age). In three of these cases, a second hypomorphic missense variant was identified.
Luciferase reporter assays were employed to assess MDA5 activity. In some cases, the second missense variant was either proven to not affect protein function or was in cis with the LoF variant.
Complete and partial MDA5 deficiency is associated with VEOIBD with variable penetrance and expressivity, suggesting a role for impaired intestinal viral sensing in IBD pathogenesis.

PMID: 11159941 - Semina et al 2001 - screened FOXE3 in a cohort of 161 unrelated individuals affected with anterior segment ocular disorders and identified a 1 bp insertion in FOXE3 in a proband and affected mother that was not found in controls. Both affected individuals had prominent anterior Schwalbe’s line (posterior embryotoxon) and cataracts.

PMID: 19708017 - Iseri et al 2009 - identified 2 pedigrees with dominant mutations in the FOXE3 gene by screening a large cohort of 236 anophthalmia-microphthalmia subjects; one with anterior segment anomalies, including Peters’ anomaly, early onset cataract, and coloboma, and another with microphthalmia,coloboma, and cerulean type (blue dot) cataracts.

PMID: 20806047 - Bremond-Ginac et al 2010 - a dominant mutation at the stop codon of FOXE3, c.959G>C (p.X320SerextX72), was identified in a patient with congenital cataract.

Analysis of lympohocytes suggests the c.959T allele is absent rather than an extended protein being expressed.

PMID: 11980846 - Ormestad et al 2002 - one individual with Peters anomaly (with eccentric corneal opacities and glaucoma but not cataract) was found to be heterozygous for a nonconservative missense mutation in FOXE3. 40% of mice heterozygous for Foxe3(dyl) have corneal and lenticular defects.

PMID: 34046667 - Reis et al 2021 - 2 families reported with dominant pathogenic extension alleles which modify the stop codon but keep the amino acids in frame, adding a 72–amino acid nonsense peptide. Cataracts were found in all cases where the lens could be evaluated.

Hereditary neuropathy v1.407 JAG1 Arina Puzriakova Added comment: Comment on list classification: New gene added by Alexander Rossor (UCL). Sullivan et al., 2020 (PMID:32065591) report two unrelated families with segregation, presenting vocal fold paresis. Knock in mouse model showed slight but nonsignificant reduction in compound muscle action potential and morphological assessments of the recurrent laryngeal nerve were normal. Mice did however display an increased frequency of axons with focally folded myelin. Notably, variants in JAG1 are associated with several phenotypes that have not included neuropathy and there was no history of cardiac, kidney, or liver disease in affected individuals in either of the two families discussed here (possibly different mechanisms of pathogenesis but further investigation may be warranted).

At this point there is not enough evidence to add this gene as diagnostic-grade; however, additional cases would corroborate this gene-disease association - rating Amber with 'watchlist' tag.

Intellectual disability v3.1249 MAP1B Arina Puzriakova edited their review of gene: MAP1B: Added comment: MAP1B was flagged by a GLH following identification of some potential cases relating to variants in this gene and predominantly ID phenotypes within 100K data. Although these are pending confirmations (will request update once cases are validated), upon reassessment of MAP1B it was highlighted that inclusion on this panels may still be warranted to increase the likelihood of detecting cases, particularly given that DD/ID is more likely to be observed earlier in the course of disease albeit at varying severities.

Adult onset hereditary spastic paraplegia v1.72 GJA1 Arina Puzriakova changed review comment from: Progressive neurological symptoms are occasionally seen in ODDD due to degeneration of the white matter tracts and can include spastic paraplegia. Gait disturbances due to spasticity can be a presenting feature for which patients initially seek medical attention. Typically signs of spasticity arise in adulthood (PMID: 18660473; 22214631; 29927410; 31023660; 33190326; 33612672); however, several adolescent onset cases (PMID: 18660473; 31023660) have also been described and I could only find a single childhood-onset case with spasticity arising at age 8 (PMID: 29927410).

Overall there is enough evidence to rate as Green on both the adult and childhood-onset HSP panels to ensure identification of all cases. >10 unrelated families reported in literature.; to: Progressive neurological symptoms are occasionally seen in ODDD due to degeneration of the white matter tracts and can include spastic paraplegia.

Overall there is enough evidence to rate as Green on the adult-onset HSP panel (>10 unrelated families reported in literature). I will seek further clinical opinion with regard to inclusion on the childhood-onset panel given the implications of carrier status being found incidentally for this primarily adult-onset condition.

PMID: 7647793 identified homozygous variants in SOD1 in 14 affected people from 4 unrelated families (some were consanguineous) from Sweden or Finland with ALS. All affected individuals are homozgyous for the the same variant (D90A). Heterozygous carriers were not affected.

PMID: 9817920 studied 28 pedigrees with D90A from around the world. The authors found that 20 recessive familes have the same founder haplotype as PMID:7647793, regardless of location, and that heterozygous carriers in these families were also unaffected. In the dominant families, 5 were sporadic (no family history of ALS) and 3 were familial and several founders existed for these families. This study shows that D90A can cause disease in a dominant fashion just like all other SOD1 variants.

Recessive inheritance of ALS caused by D90A has also been reported in families from Russia, Germany, Iran, Italy, France, Australia, Canada, and US (PMID: 18608106, 10809943, 12442272, 11284995, 11127534, 23062701).

PMID: 11220750 identified a French family with ALS, where the affected individuals were compound heterozygous for D90A and D96N in SOD1.

Palmoplantar keratoderma and erythrokeratodermas v1.20 GJA1 Arina Puzriakova changed review comment from: Comment on mode of inheritance: MOI was set to 'both mono- and biallelic' in 2017 as PPK has been observed in some patients with oculodentodigital dysplasia (ODDD). Although GJA1-related ODDD can be dominantly (MIM:164200) or recessively (MIM:257850) inherited, of the 4 unrelated families published to date with confirmed recessive ODDD (PMID: 14981729, 16816024, 20597923, 29902798) none have reported dermal abnormalities. It is possible that these may have been overlooked in the context of other more prominent features of the disorder - but this further emphasises the limited value of this panel for this particular phenotype.

GJA1 was imported to this panel from the 'Palmoplantar keratoderma and erythrokeratodermas' 100K panel and the MOI reflects the mixed inheritance pattern associated with GJA1 oculodentodigital dysplasia (ODDD) (dominant - MIM:164200; recessive - MIM:257850) which can manifest with PPK. Following the uncoupling of PPK and erythrokeratodermas into two separate GMS panels (R165 & R166), only monoallelic variants remain relevant to this particular panel.

Monoallelic variants can cause erythrokeratodermia variabilis et progressiva 3 (MIM: 617525). Erythematous palms and soles have also been described in cases of GJA1-related palmoplantar keratoderma (MIM:104100), also associated with heterozygous variants.

Two unrelated families, each with two affected sibs presenting ataxia, associated with different biallelic variants in the CHP1 gene (PMID: 29379881; 32787936). Other features include intellectual disability (3/4), cerebellar atrophy (3/4), spastic paraplegia (3/4), and neuropathy (2/4).

In vitro studies of one variant showed mutant CHP1 fails to integrate into functional complexes and impairs membrane localisation of the Na+/H+ transporter NHE1. Zebrafish and mouse models recapitulate human phenotypes such as movement defects (including ataxia), cerebellar hypoplasia, and axon abnormalities (PMID: 23904602; 29379881).

However, there are some notable differences between the two families. The age at onset differs considerably with one sib pair presenting with ataxia and cognitive decline in middle age (PMID: 32787936), in contrast to the other sibs who had infantile-onset ataxia and intellectual disability (PMID: 29379881).

CHP1 has been added to both adult and childhood-onset ataxia GMS panels, but currently the evidence only suffices for an Amber rating for each (added watchlist tag).; to: Comment on list classification: New gene added by Julia Baptista (RD&E_NHS).

Penetrance for gene: RNF220 were set to Complete
Review for gene: RNF220 was set to GREEN
Added comment: Sferra et al (2021 - PMID: 33964137) provide extensive evidence that biallelic RNF220 mutations cause a disorder characterized by hypomyelinating leukodystrophy, ataxia (9/9 - onset 1-5y), borderline intellectual functioning (3/9) / intellectual disability (5/9 - in most cases mild), sensorineural deafness (9/9) with complete hearing loss in the first decade of life, hepatopathy (9/9) with associated periportal fibrosis, and dilated cardiomyopathy (9/9) which was fatal.

Other neurologic manifestations apart from ataxia incl. hyperreflexia (8/8), spastic paraplegia (9/9), dysarthria (9/9), peripheral neuropathy (4/9), seizures in one case (1/9). Upon brain MRI there was thin corpus callosum (9/9) or cerebellar atrophy in some (2/9).

The authors identified homozygosity for 2 recurrent missense RNF220 variants in affected members belonging to these 5 broad consanguineous pedigrees (7 families), namely NM_018150.4:c.1094G>A / p.Arg365Gly in 4 Roma families in the context of a shared haplotype (/founder effect) as well as c.1088G>A / p.Arg363Gly in a large pedigree from southern Italy initially reported by Leuzzi et al (2000 - PMID: 10881263).

Extensive segregation analyses were carried out including several affected and unaffected members.

RNF220 encodes ring finger protein 220, which functions as an E3 ubiquitin ligase. Previous studies have shown among others a role in modulation of Sonic hedgehog/GLI signaling and cerebellar development

Evidence for the role of RNF220 included relevant expression, localization within the cell, interaction partners (lamin B1, 20S proteasome), similarities with other laminopathies in terms of phenotype, etc :
*RNF220 has a relevant expression pattern in CNS (based on qRT-PCR analyses in human brain, cerebellum, cerebral cortex / mRNA levels in human fetal CNS with higher expression in cerebellum, spinal cord and cortex / previous GTEx data / protein levels in mouse CNS)
*The protein displays nuclear localization based on iPSC cells differentiated to motor neurons (also supported by data from the Human Protein Atlas). Transfection of COS-1 cells demonstrated localization primarily to the nucleus (as also previously demonstrated in HEK293T cells) in vesicle like structures with ASF2/SF2 colocalization suggesting enrichment in nuclear speckles. There was also partial co-distribution with the 20S proteasome. R363Q and R365Q additionally coalesced in the cytoplasm forming protein aggregates/inclusions.
*Immunofluorescence studies in patient fibroblasts also confirmed abnormal increase of the protein in the cytoplasm and increased fluorescence with the 20S proteasome.
*Proteomic identification of RNF220-interacting proteins in transfected HEK293T cells demonstrated enrichment for all members of the lamin protein family (incl . lamin B1, AC, B2).
*RNAi-mediated downregulation of RNF222 in Drosophila suggested altered subcellular localization and accumulation of the fly orthologue for human lamin B1.
*Immunoprecipitation of lamin B1 from the nuclear matrix of cerebellar cells suggested significant interaction of endogenous lamin B1 with RNF220, while transfection studies in HEK293T cells for wt/mt suggested reduced binding to endogenous lamin B1 for RNF220 mt compared to wt (more prominent for R365Q). RNF220 mutants also reduced ubiquitination of nuclear lamin B1 compared to wt.
*Patient fibroblasts immunostained with different nuclear envelope markers displayed abnormal nuclear shapes with multiple invaginations and lobulations, findings also observed in laminopathies.

There is currently no associated phenotype in OMIM or G2P. SysID includes RNF220 among the current primary ID genes.

Consider inclusion in panels for leukodystrophies, childhood onset ataxia, sensorineural hearing loss, corpus callosum anomalies, cardiomyopathies, hepatopathies, etc in all cases with green rating.

Added comment: Sakamoto et al (2021 - PMID: 34346499) provide some evidence that monoallelic ARF3 pathogenic variants may be associated with a NDD with brain abnormality.

Using trio exome sequencing, the authors identified 2 individuals with NDD harboring de novo ARF3 variants, namely: NM_001659.2:c.200A>T / p.Asp67Val and c.296G>T / p.Arg99Leu.

Individual 1 (with Asp67Val / age : 4y10m), appeared to be more severelely affected with prenatal onset progressive microcephaly, severe global DD, epilepsy. Upon MRI there was cerebellar and brainstem atrophy. Individual 2 (Arg99Leu / 14y) had severe DD and ID (IQ of 23), epilepsy and upon MRI cerebellar hypoplasia. This subject did not exhibit microcephaly. Common facial features incl. broad nose, full cheeks, small philtrum, strabismus, thin upper lips and abnormal jaw. There was no evidence of systemic involvement in both.

ARF3 encodes ADP-ribosylation factor 3. Adenosine diphosphate ribosylation factors (ARFs) are key proteins for regulation of cargo sorting at the Golgi network, with ARF3 mainly working at the trans-Golgi network. ARFs belong to the small GTP-binding protein (G protein) superfamily. ARF3 switches between an active GTP-bound form and an inactive GDP-bound form, regulated by guanine nucleotide exchange factors (GEFs) and GTPase activating proteins (GAPs) respectively.

Members of the ARF superfamily regulate various aspects of membrane traffic, among others in neurons.

There are 5 homologs of ARF families, divided in 3 classes. ARF3 and ARF1 belong to class I. Monoallelic ARF1 mutations are associated with Periventricular nodular heterotopia 8 (MIM 618185).

In vivo, in vitro and in silico studies for the 2 variants suggest that both impair the Golgi transport system although each variant most likely exerts a different effect (gain-of-function for Arg99Leu vs loss-of-function/dominant-negative for Asp67Val).

This was also reflected in somewhat different phenotype of the subjects with the respective variants. Common features included severe DD, epilepsy and brain abnormalities although Asp67Val was associated with diffuse brain atrophy as well as congenital microcephaly and Arg99Leu with cerebellar hypoplasia.

Evidence to support the effect of each variant include:

Arg99Leu:
Had identical Golgi localization to that of wt
Had increased binding activity with GGA1, a protein recruited by the GTP-bound active form of ARF3 to the TGN membrane (supporting GoF)
In silico structural analysis suggested it may fail to stabilize the conformation of Asp26, resulting in impaired GTP hydrolysis (GoF).
In transgenic fruit flies, evaluation of the ARF3 variant toxicity using the rough eye phenotype this variant was associated with increased severity of the r-e phenotype similar to a previously studied GoF variant (Gln71Leu)

Asp67Val:
Did not show a Golgi-like pattern of localization (similar to Thr31Asn a previously studied dominant-negative variant)
Displayed decreased protein stability
In silico structural analysis suggested that Asp67Val may lead to compromised binding of GTP or GDP (suggestive of LoF)
In transgenic Drosophila eye-specific expression of Asp67Val (similar to Thr31Asn, a known dominant-negative variant) was lethal possibly due to high toxicity in very small amounts in tissues outside the eye.

There is no associated phenotype in OMIM, G2P or SysID.

Added comment: Sakamoto et al (2021 - PMID: 34346499) provide some evidence that monoallelic ARF3 pathogenic variants may be associated with a NDD with brain abnormality.

Using trio exome sequencing, the authors identified 2 individuals with NDD harboring de novo ARF3 variants, namely: NM_001659.2:c.200A>T / p.Asp67Val and c.296G>T / p.Arg99Leu.

Intellectual disability v3.1220 PLXNA2 Konstantinos Varvagiannis changed review comment from: Altuame et al (2021 - PMID: 34327814) describe 3 individuals from 2 consanguineous Arab families with biallelic PLXNA2 variants.

The index patient from the 1st family presented with CHD (hypoplastic right ventricle, ASD), DD and moderate ID (IQ of 40), failure to thrive as well as some dysmorphic features (obtuse mandibular angle, mild overbite, synophrys with downslanting p-f, strabismus, etc). There were additional features (eg. postaxial polydactyly) which were found in other affected and unaffected family members.

Exome sequencing with autozygome analysis revealed homozygosity for a PLXNA2 stopgain variant (NM_025179:c.3603C>A / p.(Cys1201*)).

Sanger confirmation was carried out and segregation analyses confirmed carrier status of the unaffected parents and a sib as well as a brother homozygous for the same variant. Clinical evaluation of the latter, following this finding revealed borderline intellectual functioning, ADHD, failure to thrive. There was no mandibular anomaly or overbite and no clinical evidence of CHD (no echo performed).

The index patient from the 2nd consanguineous family was evaluated for ID (IQ of 63), with previous borderline motor development, ADHD and some dysmorphic features (obtuse mandibular angle and overbite). There was no clinical evidence of CHD (no echo performed).

Exome sequencing with autozygosity mapping revealed a homozygous missense PLXNA2 variant (c.3073G>A / p.(Asp1025Asn), present only once in gnomAD (htz), with rather non-concordant in silico predictions SIFT 0.22, PolyPhen 0.682 and CADD 23.5. The aa was however highly conserved.

Segregation analysis confirmed carrier state of the parents and 2 unaffected sibs, with a 3rd sib homozygous for the wt allele.

As the authors discuss:
*PLXNA2 belongs to the plexin family of genes, encoding transmbembrane proteins functioning as semaphorin receptors. It has predominant expression in neural tissue. The protein is thought to bind semaphorin-3A, -3C or -5 followed by plexin A2 dimerization, activation of its GTPase-activating protein domain, negative regulation of Rap1B GTPase and initiation of a signal transduction cascade mediating axonal repulsion/guidance, dendritic guidance, neuronal migration.
*Murine Plxna2 knockout models display structural brain defects. In addition they display congenital heart defects incl. persistent truncus arteriosus and interrupted aortic arch.
*Rare CNVs in adult humans with tetralogy of Fallot have suggested a potential role of PLXNA2 in cardiac development and CHD.
*Expression and the role of PLXNA2 in human chondrocytes as well as a GWAS in 240 japanese patients with mandibular prognathism where PLXNA2 was suggested as a susceptibility locus.

Overall, the authors recognize some common features (as for cognitive functioning, some dysmorphic features incl. obtuse mandibular angle and overbite in 2 unrelated subjects, failure to thrive 3/3) and provide plausible explanations for the variability / discordance of others eg:
- Cyanotic heart disease explaining discordance in cognitive outcome among sibs
- Incomplete penetrance for CHD (and/or ID or mandibular anomaly) as for few AR disorders and/or
- Additional pathogenic variants explaining the CHD in the first subject.

There is no associated phenotype in OMIM or G2P. SysID includes PLXNA2 among the candidate ID genes.

Intellectual disability v3.1220 VPS50 Konstantinos Varvagiannis gene: VPS50 was added
gene: VPS50 was added to Intellectual disability. Sources: Literature
Mode of inheritance for gene: VPS50 was set to BIALLELIC, autosomal or pseudoautosomal
Publications for gene: VPS50 were set to 34037727
Phenotypes for gene: VPS50 were set to Neonatal cholestatic liver disease; Failure to thrive; Profound global developmental delay; Postnatal microcephaly; Seizures; Abnormality of the corpus callosum
Penetrance for gene: VPS50 were set to Complete
Review for gene: VPS50 was set to AMBER
Added comment: Schneeberger et al (2021 - PMID: 34037727) describe the phenotype of 2 unrelated individuals with biallelic VPS50 variants.

Common features included transient neonatal cholestasis, failure to thrive, severe DD with failure to achieve milestones (last examination at 2y and 2y2m respectively), postnatal microcephaly, seizures (onset at 6m and 25m) and irritability. There was corpus callosum hypoplasia on brain imaging.

Both individuals were homozygous for variants private to each family (no/not known consanguinity applying to each case). The first individual was homozygous for a splicing variant (NM_017667.4:c.1978-1G>T) and had a similarly unaffected sister deceased with no available DNA for testing. The other individual was homozygous for an in-frame deletion (c.1823_1825delCAA / p.(Thr608del)).

VPS50 encodes a critical component of the endosome-associated recycling protein (EARP) complex, which functions in recycling endocytic vesicles back to the plasma membrane [OMIM based on Schindler et al]. The complex contains VPS50, VPS51, VPS52, VPS53, the three latter also being components of GARP (Golgi-associated-retrograde protein) complex. GARP contains VPS54 instead of VPS50 and is required for trafficking of proteins to the trans-golgi network. Thus VPS50 (also named syndetin) and VPS54 function in the EARP and GARP complexes, to define directional movement of their endocytic vesicles [OMIM based on Schindler et al]. The VPS50 subunit is required for recycling of the transferrin receptor.

As discussed by Schneeberger et al (refs provided in text):
- VPS50 has a high expression in mouse and human brain as well as throughout mouse brain development.
- Mice deficient for Vps50 have not been reported. vps50 knockdown in zebrafish results in severe developmental defects of the body axis. Knockout mice for other proteins of the EARP/GARP complex (e.g. Vps52, 53 and 54) display embryonic lethality.

Studies performed by Schneeberger et al included:
- Transcript analysis for the 1st variant demonstrated skipping of ex21 (in patient derived fabriblasts) leading to an in frame deletion of 81 bp (r.1978_2058del) with predicted loss of 27 residues (p.Leu660_Leu686del).
- Similar VPS50 mRNA levels but significant reduction of protein levels (~5% and ~8% of controls) were observed in fibroblasts from patients 1 and 2. Additionally, significant reductions in the amounts of VPS52 and VPS53 protein levels were observed despite mRNA levels similar to controls. Overall, this suggested drastic reduction of functional EARP complex levels.
- Lysosomes appeared to have similar morphology, cellular distribution and likely unaffected function in patient fibroblasts.
- Transferrin receptor recycling was shown to be delayed in patient fibroblasts suggestive of compromise of endocytic-recycling function.

As the authors comment, the phenotype of both individuals with biallelic VPS50 variants overlaps with the corresponding phenotype reported in 15 subjects with biallelic VPS53 or VPS51 mutations notably, severe DD/ID, microcephaly and early onset epilepsy, CC anomalies. Overall, for this group, they propose the term "GARP and/or EARP deficiency disorders".

There is no VPS50-associated phenotype in OMIM or G2P. SysID includes VPS50 among the ID candidate genes.

Consider inclusion in other relevant gene panels (e.g. for neonatal cholestasis, epilepsy, microcephaly, growth failure in early infancy, corpus callosum anomalies, etc) with amber rating pending further reports.

Primary immunodeficiency or monogenic inflammatory bowel disease v2.455 GIMAP5 Arina Puzriakova commented on gene: GIMAP5: Cannot access new publication identified by Zornitza Stark (PMID:33956074) - free text will be available from 05/01/2022. OMIM entry states that "some patients may have recurrent infections or features suggestive of an immunodeficiency" but it is unclear how many individuals were affected and to what extent. Liver dysfunction (portal hypertension, liver failure) seems to be the more prominent phenotype in these cases but currently there are no relevant PanelApp panels for this. Therefore, I will maintain the Amber rating at this time, until publications become available or further evidence emerges.
Childhood solid tumours v2.23 NYNRIN Arina Puzriakova Classified gene: NYNRIN as Amber List (moderate evidence)

Mahamdallie et al. 2019 (PMID: 30885698) report 2 families with 3 affected children with Wilms tumour who harboured distinct compound het protein-truncating variants in this gene. To date, there have been no further reports linking NYNRIN with disease and little is known about its functions. Rating Amber as two families have been identified but additional cases/functional evidence are required to validate pathogenicity.

Review for gene: MOCOS was set to GREEN
Added comment: This gene had not been previously included in this panel, but there is good evidence from several publications that recessive loss-of-function variants in MOCOS are associated with Xanthinuria type 2. There is also a good pathophysiologic basis: MOCOS encodes a necessary co-factor for the 2 enzymes that degrade Xanthine, XDH and AOX1.
Moreover, there are spontaneous animal models, with MOCOS variants identified in a goat (PMID 30758870) and Tyrolean grey cattle (PMID 27919260).

Early onset or syndromic epilepsy v2.402 PIDD1 Konstantinos Varvagiannis changed review comment from: There is enough evidence to include this gene in the current panel with green rating.

Biallelic PIDD1 pathogenic variants have been reported in 26 individuals (11 families) with DD (all), variable degrees of ID (mild to severe), behavioral (eg. aggression/self-mutilation in several, ADHD) and/or psychiatric abnormalities (ASD, psychosis in 5 belonging to 3 families), well-controlled epilepsy is some (9 subjects from 6 families) and MRI abnormalities notably abnormal gyration pattern (pachygyria with predominant anterior gradient) as well as corpus callosum anomalies (commonly thinning) in several. Dysmorphic features have been reported in almost all, although there has been no specific feature suggested.

The first reports on the phenotype associated with biallelic PIDD1 mutations were made by Harripaul et al (2018 - PMID: 28397838) and Hu et al (2019 - PMID: 29302074) [both studies investigating large cohorts of individuals with ID from consanguineous families].

Sheikh et al (2021 - PMID: 33414379) provided details on the phenotype of 15 individuals from 5 families including those from the previous 2 reports and studied provided evidence on the role of PIDD1 and the effect of variants.

Zaki et al (2021 - PMID: 34163010) reported 11 additional individuals from 6 consanguineous families, summarize the features of all subjects published in the literature and review the neuroradiological features of the disorder.

PIDD1 encodes p53-induced death domain protein 1. The protein is part of the PIDDosome, a multiprotein complex also composed of the bipartite linker protein CRADD (also known as RAIDD) and the proform of caspase-2 and induces apoptosis in response to DNA damage.

There are 5 potential PIDD1 mRNA transcript variants with NM_145886.4 corresponding to the longest. Similar to the protein encoded by CRADD, PIDD1 contains a death domain (DD - aa 774-893). Constitutive post-translational processing gives PIDD1-N, PIDD1-C the latter further processed into PIDD1-CC (by auto-cleavage). Serine residues at pos. 446 and 588 are involved in this autoprocessing generating PIDD1-C (aa 446-910) and PIDD1-CC (aa 774-893). The latter is needed for caspase-2 activation.

Most (if not all) individuals belonged to consanguineous families of different origins and harbored pLoF or missense variants.

Variants reported so far include : c.2587C>T; p.Gln863* / c.1909C>T ; p.Arg637* / c.2443C>T / p.Arg815Trp / c.2275-1G>A which upon trap assay was shown to lead to skipping of ex15 with direct splicing form exon14 to the terminal exon 16 (resulting to p.Arg759Glyfs*1 with exlcusion of the entire DD) / c.2584C>T; p.Arg862Trp / c.1340G>A; p.Trp447* / c.2116_2120del; p.Val706His*, c.1564_1565del; p.Gly602fs*26

Evidence so far provided includes:
- Biallelic CRADD variants cause a NDD disorder and a highly similar gyration pattern.
- Confirmation of splicing effect (eg. for c.2275-1G>A premature stop in position 760) or poor expression (NM_145886.3:c.2587C>T; p.Gln863*). Arg815Trp did not affect autoprocessing or protein stability.
- Abnormal localization pattern, loss of interaction with CRADD and failure to activate caspase-2 (MDM2 cleavage assay) [p.Gln863* and Arg815Trp]
- Available expression data from GTEx (PIDD1 having broad expression in multiple tissues, but higher in brain cerebellum) as well as BrainSpan and PsychEncode studies suggesting high coexpression of PIDD1, CRADD and CASP2 in many regions in the developing human brain.
- Variants in other genes encoding proteins interacting with PIDD1 (MADD, FADD, DNAJ, etc) are associated with NDD.

Pidd-1 ko mice (ex3-15 removal) lack however CNS-related phenotypes. These show decreased anxiety but no motor anomalies. This has also been the case with Cradd-/- mice displaying no significant CNS phenotypes without lamination defects.

There is currently no associated phenotype in OMIM, PanelApp Australia. PIDD1 is listed in the DD panel of G2P (PIDD1-relared NDD / biallelic / loss of function / probable) . SysID includes PIDD1 among the current primary ID genes.

Overall the gene appears to be relevant for the epilepsy panel, panels for gyration and/or corpus callosum anomalies etc.

PIDD1 encodes p53-induced death domain protein 1. The protein is part of the PIDDosome, a multiprotein complex also composed of the bipartite linker protein CRADD (also known as RAIDD) and the proform of caspase-2 and induces apoptosis in response to DNA damage.

There are 5 potential PIDD1 mRNA transcript variants with NM_145886.4 corresponding to the longest. Similar to the protein encoded by CRADD, PIDD1 contains a death domain (DD - aa 774-893). Constitutive post-translational processing gives PIDD1-N, PIDD1-C the latter further processed into PIDD1-CC (by auto-cleavage). Serine residues at pos. 446 and 588 are involved in this autoprocessing generating PIDD1-C (aa 446-910) and PIDD1-CC (aa 774-893). The latter is needed for caspase-2 activation.

Most (if not all) individuals belonged to consanguineous families of different origins and harbored pLoF or missense variants.

Variants reported so far include : c.2587C>T; p.Gln863* / c.1909C>T ; p.Arg637* / c.2443C>T / p.Arg815Trp / c.2275-1G>A which upon trap assay was shown to lead to skipping of ex15 with direct splicing form exon14 to the terminal exon 16 (resulting to p.Arg759Glyfs*1 with exlcusion of the entire DD) / c.2584C>T; p.Arg862Trp / c.1340G>A; p.Trp447* / c.2116_2120del; p.Val706His*, c.1564_1565del; p.Gly602fs*26

Evidence so far provided includes:
- Biallelic CRADD variants cause a NDD disorder and a highly similar gyration pattern.
- Confirmation of splicing effect (eg. for c.2275-1G>A premature stop in position 760) or poor expression (NM_145886.3:c.2587C>T; p.Gln863*). Arg815Trp did not affect autoprocessing or protein stability.
- Abnormal localization pattern, loss of interaction with CRADD and failure to activate caspase-2 (MDM2 cleavage assay) [p.Gln863* and Arg815Trp]
- Available expression data from GTEx (PIDD1 having broad expression in multiple tissues, but higher in brain cerebellum) as well as BrainSpan and PsychEncode studies suggesting high coexpression of PIDD1, CRADD and CASP2 in many regions in the developing human brain.
- Variants in other genes encoding proteins interacting with PIDD1 (MADD, FADD, DNAJ, etc) are associated with NDD.

Pidd-1 ko mice (ex3-15 removal) lack however CNS-related phenotypes. These show decreased anxiety but no motor anomalies. This has also been the case with Cradd-/- mice displaying no significant CNS phenotypes without lamination defects.

There is currently no associated phenotype in OMIM, PanelApp Australia. PIDD1 is listed in the DD panel of G2P (PIDD1-related NDD / biallelic / loss of function / probable) . SysID includes PIDD1 among the current primary ID genes.

Overall the gene appears to be relevant for the epilepsy panel, panels for gyration and/or corpus callosum anomalies etc.

Primary immunodeficiency or monogenic inflammatory bowel disease v2.454 RGS10 Arina Puzriakova Added comment: Comment on list classification: New gene added by Boaz Palterer. Single family with 3 affected sibs reported (PMID:34315806), who presented with short stature and immunodeficiency and harboured compound het variants in RGS10 that segregated with disease. However, the sibs also carried a heterozygous PIK3CD (E525K) variant that has previously been deemed pathogenic in Activated PI3 Kinase Delta Syndrome (APDS), a primary immunodeficiency. The variant was excluded as the father also carried the PIK3CD variant but was mostly healthy and none of the 3 affected sibs displayed the full spectrum of symptoms associated with APDS. Nonetheless, APDS is a clinically heterogeneous condition with variable penetrance among affected individuals and so the contribution of PIK3CD to the patients immune dysregulation cannot be completely ruled out.

There are no further reports of an association between RGS10 variants and immunodeficiency to date, and therefore rating Red until further evidence emerges.

Added comment: Twenty individuals from seven families reported with de novo or transmitted haploinsufficient variants in SF3B2. Affected individuals had mandibular hypoplasia, microtia, facial and preauricular tags, epibulbar dermoids, lateral oral clefts in addition to skeletal and cardiac abnormalities.

Targeted morpholino knockdown of SF3B2 in Xenopus resulted in disruption of cranial neural crest precursor formation and subsequent craniofacial cartilage defects, supporting a link between spliceosome mutations and impaired neural crest development in congenital craniofacial disease.

The families were ascertained from a cohort and the authors suggest that haploinsufficient variants in SF3B2 are the most prevalent genetic cause of CFM, explaining ~3% of sporadic and ~25% of familial cases.

Added comment: 11 individuals reported, 9 that carried 8 different rare heterozygous missense variants in CLCN3, and 2 siblings that were homozygous for an NMD-predicted frameshift variant likely abolishing ClC-3 function. All missense variants were confirmed to be de novo in eight individuals for whom parental data was available.

The 11 individuals in the cohort share clinical features of variable severity. All 11 have GDD or ID and dysmorphic features, and a majority has mood or behavioural disorders and structural brain abnormalities:
- Structural brain abnormalities on MRI (9/11) included partial or full agenesis of the corpus callosum (6/9), disorganized cerebellar folia (4/9), delayed myelination (3/9), decreased white matter volume (3/9), pons hypoplasia (3/9), and dysmorphic dentate nuclei (3/9). Six of those with brain abnormalities also presented with seizures.
- Nine have abnormal vision, including strabismus in four and inability to fix or follow in the two with homozygous loss-of-function variants.
- Hypotonia ranging from mild to severe was reported in 7 of the 11 individuals.
- Six have mood or behavioural disorders, particularly anxiety (3/6).
- Consistent dysmorphic facial features included microcephaly, prominent forehead, hypertelorism, down-slanting palpebral fissures, full cheeks, and micrognathia.

The severity of disease in the two siblings with homozygous disruption of ClC-3 is consistent with the drastic phenotype seen in Clcn3 KO mice. The disease was more severe in two siblings carrying homozygous loss-of-function variants with the presence of GDD, absent speech, seizures, and salt and pepper fundal pigmentation in both individuals, with one deceased at 14 months of age. The siblings also had significant neuroanatomical findings including diffusely decreased white matter volume, thin corpora callosa, small hippocampi, and disorganized cerebellar folia. Supporting biallelic inheritance for LoF variants, disruption of mouse Clcn3 results in drastic neurodegeneration with loss of the hippocampus a few months after birth and early retinal degeneration. Clcn3−/− mice display severe neurodegeneration, whereas heterozygous Clcn3+/− mice appear normal.

Patch-clamp studies were used to investigate four of the missense variants. These suggested a gain of function in two variants with increased current in HEK cells, however they also showed reduced rectification of voltage and a loss of transient current, plus decreased current amplitude, glycosylation and surface expression when expressed in oocytes, and were suspected to interfere with channel gating and a negative feedback mechanism. These effects were also shown to vary depending on pH levels. The current of the remaining two variants did not differ from WT. For heterozygous missense variants, the disruption induced may be at least partially conferred to mutant/WT homodimers and mutant/ClC-4 heterodimers.

Both loss and gain of function in this gene resulted in the same phenotype.

Green for mono-allelic variants, Amber/Red for bi-allelic.

Added comment: Biallelic variants in 5 unrelated families with early onset (median 21 years , range 13-22 years) with ataxia with variable additional hyper- and hypokinetic movement disorders, and severe early-onset cerebellar atrophy (seen on MRI), and involvement of the brainstem, medullary olive and parietal cortex.

Evolution of the disease was gait ataxia leading to upper limb ataxia, then dysarthria and then dysphagia, all within a decade. For some of these patients, the phenotype included myoclonus, dystonia and / or tremor. Mild classical mitochondrial features were seen in one of the patients, namely ptosis and COX-negative fibres.

The variants were homozygous nonsense, homozygous frameshift, homozygous missense, and a compound heterozygote with a splice variant and missense, all leading to complete loss of the protein. Oxidative stress and mitochondrial dysfunction was indicated as the disease mechanism.

The families originated from Germany, France, India and two from eastern Turkey. The two families from Turkey were seemingly unrelated to each other but had the same homozygous missense, suggestive of founder effect.

Patient fibroblasts from each of the five probands showed lack of protein (via Western blot) and decreased glutathione peroxidase activity and decreased mitochondrial maximal respiratory capacity.

PRDX3 encodes peroxiredoxin 3, a mitochondrial antioxidant protein, that catalyses the reduction of hydrogen peroxide. It localises in the mitochondria, where most hydrogen peroxide is generated.

Functional studies: PRDX3 knockdown (induced by silencing RNA against PRDX3) in cerebellar medulloblastoma cells showed significantly decreased cell viability, increased hydrogen peroxide levels and increased susceptibility to apoptosis triggered by reactive oxygen species.

In addition, induced knockdown drosophila (in vivo animal model) had aberrant locomotor phenotypes and reduced lifespans, while immunolabelling of the brain showed increased cell death after exposure to oxidative stress.

Added comment: 6 unrelated individuals
1x individual in a dystonia cohort index case with infancy-onset dystonia and other neurological manifestations with a de-novo missense variant, c.338G>A (p.Gly113Glu) in IMPDH2, predicted to disrupt an invariant residue within the cystathionine-β-synthase (CBS) domain pair of the encoded protein.
IMPDH2 encodes IMPDH2, a key enzyme in the purine biosynthetic pathway, expressed throughout the brain and not linked previously to any human Mendelian condition.
1x individual with a de-novo substitution, c.337G>A (p.Gly113Arg), was found in in-house whole-exome sequencing data from 500 individuals with neurodevelopmental disorders. Through GeneMatcher, de novo variants identified:
3 x missense: c.729G>C (p.Gln243His), c.619G>C (p.Gly207Arg), and c.619G>A (p.Gly207Arg)
1 x deletion: c.478_480delTCC (p.Ser160del)
The six variants were predicted to be deleterious and none of them seen in control databases. All affected conserved amino acids and resided in and around the cystathionine-β-synthase domain pair.
The described variants are situated in and around the CBS domain pair, a regulatory element in which clustering of pathogenic missense variants has already been shown for the homologue of IMPDH2, IMPDH1.

All individuals shared similar neurodevelopmental phenotypes. Apart from the dystonia cohort index case, one participant had evidence of dystonic posturing.

Modelling of the variants on 3D protein structures revealed spatial clustering near specific functional sites, predicted to result in deregulation of IMPDH2 activity. Additionally, thermal-shift assays showed that the c.619G>A (p.Gly207Arg) variant, identified as within the CBS domain pair, and c.729G>C (p.Gln243His), which is in close vicinity, affected the stability or folding behaviour of IMPDH2.

Added comment: KIF1A is associated HSP type 30 (MIM# 610357) which can be inherited recessively or dominantly, as well as NESCAV syndrome (MIM# 614255) caused by heterozygous variants in this gene.

Cerebellar signs including: ataxia; dysmetria; and saccadic ocular pursuit, associated with mild cerebellar atrophy, were reported in 2/4 families with recessive HSP (PMID: 21487076; 22258533; 28332297).

Variable ataxic features, cerebellar signs and cerebellar atrophy have been described in multiple cases with the complex forms of dominant KIF1A-related HSP (PMID: 31805580; 32737135), but these features are even more prominent in individuals with NESCAV syndrome (PMID: 25265257; 26125038; 26354034; 32096284; 34121983).

Of note, at least 11 heterozygous cases have been described in which congenital or early onset ataxia with cerebellar signs was the presenting clinical feature (PMID: 26354034; 32737135; 32746806; https://doi.org/10.1016/j.ejpn.2017.04.926)

Familial dysautonomia v1.13 KIF1A Arina Puzriakova Added comment: Comment on mode of inheritance: Changed MOI from 'biallelic' to 'both mono- and biallelic' - features of dysautonomia are observed in multiple KIF1A-related phenotypes, including an autonomic-sensory neuropathy (MIM# 614213) associated with biallelic inheritance and NESCAV syndrome (MIM# 614255) caused by monoallelic variants in this gene. Therefore, both MOIs are pertinent to this panel.

Hereditary neuropathy or pain disorder v1.35 KIF1A Arina Puzriakova Added comment: Comment on mode of inheritance: Biallelic variants are associated with autonomic-sensory neuropathy (MIM# 614213). KIF1A is also associated HSP type 30 (MIM# 610357) which can be inherited recessively or dominantly, as well as NESCAV syndrome (MIM# 614255) caused by heterozygous variants in this gene - both monoallelic conditions have been shown to include peripheral sensorimotor neuropathy.

For this reason, the MOI could be changed from 'biallelic' to 'both mono- and biallelic' if it is decided to include genes on this panel that cause neuropathy as part of a more complex phenotype (tagged for GMS review)
