Fetal anomalies v1.977 AP1S2 Arina Puzriakova changed review comment from: 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.; to: Comment on mode of inheritance: Review of literature did not reveal any confirmed affected females.

Fetal anomalies v1.705 PRKD1 Arina Puzriakova Added comment: Comment on mode of inheritance: MOI was reassessed following a recent review by Zornitza Stark highlighting the potential involvement of biallelic variants. Currently the evidence for biallelic inheritance only suffices for an Amber rating and so I have kept the MOI as monoallelic but with a 'watchlist_MOI' tag to monitor for additional evidence. The Genomics England pipeline would still pick up biallelic cases under the current MOI.

Fetal anomalies v1.40 TUBA8 Rebecca Foulger commented on gene: TUBA8: In 4 affected members of 2 consanguineous Pakistani families with MIM:613180, Abdollahi et al. (2009, PMID:19896110) identified a homozygous 14-bp deletion 11 bp upstream of the exon 2 splice site junction in TUBA8. The families may have common ancestory. All obligate carriers were heterozygous. The patients had neonatal hypotonia, profound mental retardation, essentially no psychomotor development, optic nerve hypoplasia, and thickened cortex with polymicrogyria and absent corpus callosum. BUT due to lack of a mouse TUBA8 phenotype, the authors in PMID:28388629 (Diggle et al 2017) reanalysed their patients from PMID:19896110 and found an additional LOF variant in SNAP29 (p.Ser163Lysfs*6). The authors suggest that SNAP29 deficiency, rather than TUBA8 deficiency, may be responsible for the patient phenotypes.
Fetal anomalies v0.357 CRYBB1 Rebecca Foulger Added comment: Comment on mode of inheritance: Although the 'confirmed' disorder in DDG2P has 'monoallelic' inheritance (and 'probable' rating for the biallelic disorders), have kept the MOI as 'both AD and AR' on the fetal panel so all cataract cases are picked up.
Fetal anomalies v0.328 SLC4A4 Rebecca Foulger commented on gene: SLC4A4: SLC4A4 was re-reviewed by Anna de Burca (Genomics England clinical team) to determine if patients presented with cataracts. Anna notes that there aren’t very many published cases and not all had cataracts. Of those that did, PMID:16636648 cataracts were definitely not congenital and in PMID:11131345 they were only picked up at 4 years so probably not congenital either. Therefore appropriate to remain Red.
Fetal anomalies v0.328 VDR Rebecca Foulger Added comment: Comment on list classification: Demoted rating from Green to Amber following discussions with Anna de Burca (Genomics England Clinical Team) and Rhiannon Mellis (Great Ormond Street). As Anna and Rhiannon note: rickets due to VDR could theoretically present in a fetus of a homozygous mother, as Melita suggested, but it would actually be caused by the mother’s vitamin D status irrespective of the baby’s genotype. Therefore, rather than performing a fetal exome, it would be better investigating the mother, who would have clinical signs and biochemical abnormalities in her own right.
Fetal anomalies v0.311 ABCC8 Rebecca Foulger edited their review of gene: ABCC8: Added comment: This gene was reviewed by Anna de Burca (Genomics England Clinical Team) and Karen Temple. Outcome of review: Growth restriction is less marked but queried whether hyperinsulinaemia might cause features that would be picked up on scan. Rate as Red.; Changed rating: RED
Fetal anomalies v0.311 MRPS22 Rebecca Foulger edited their review of gene: MRPS22: Added comment: This gene was re-reviewed in a consistency check by Anna de Burca (Genomics England Clinical Team). Outcome of review: Yates et al study (PMID:28425981) pulled out a pathogenic variant in MRPS22 in a deceased fetal case with Hydrops, CNS malformations and cardiomyopathy picked up on U/S scan. Additional info from OMIM: A boy with oxidative phosphorylation defect in PMID:21189481 who had microcephaly, dysmorphic features etc at birth. 3 siblings in PMID:17873122. Therefore if include Yates et al, there are 3 cases. ; Changed rating: GREEN; Changed publications: 17873122, 21189481
Fetal anomalies v0.290 KIAA1109 Rebecca Foulger commented on gene: KIAA1109: PMID:30485398: Filatova et al. 2019 report a Russian family with fetal anomalies detected upon ultrasound scans of three pregnancies. The first pregnancy resulted in a miscarriage. The second and third pregnancies were terminated because of ultrasound fetal abnormalities. In the third pregnancy, anomalies included bilateral ventriculomegaly, arthrogryposis (radial clubhand, bilateral clubfoot, flexed deformity of hip, knee and ankle joints), bilateral pyelectasis, increased thickness of the nuchal‐fold, hypoplastic and low set ears- Sanger sequencing revealed that the polymalformative fetus had compound heterozygous KIAA1109 variants. One of the dichorionic twins in the 4th pregnancy had similar phenotype and biallelic KIAA1109 variants (the healthy twin had only one variant c.1932‐3A>G).
Fetal anomalies v0.222 TBX22 Rebecca Foulger commented on gene: TBX22: This gene and phenotype were reviewed during meetings at Great Ormond Street hospital in March and April 2019. Clinical review and curation was performed by Lyn Chitty, Anna de Burca, Rhiannon Mellis, Richard Scott, Ellen McDonagh and Rebecca Foulger. Outcome of review: Phenotype is fetally-relevant but limited evidence: include on the Fetal anomalies panel as an Amber gene. Additional notes from clinical review: Amber for Abruzzo-Erickson syndrome (MIM: 302905) due to the limited evidence. The clefting phenotype has sufficient cases but is isolated cleft palate so unlikely to be seen prenatally (confirmed by Lyn Chitty, 26th April 2019). Therefore demote from Green to Amber.
Fetal anomalies v0.222 ABCD1 Rebecca Foulger edited their review of gene: ABCD1: Added comment: This gene and phenotype were reviewed during meetings at Great Ormond Street hospital in March and April 2019. Clinical review and curation was performed by Lyn Chitty, Anna de Burca, Rhiannon Mellis, Richard Scott, Ellen McDonagh and Rebecca Foulger. Originally rated Amber based on DDG2P Disease confidence of 'both DD and IF' for at least one disorder. Outcome of review: Phenotype is not fetally-relevant. Additional notes from clinical review: Childhood onset and progressive- Nothing would be picked up fetally. Action taken: Demoted ABCD1 gene rating from Amber to Red.; Changed rating: RED
Fetal anomalies v0.158 TBX22 Rebecca Foulger Added comment: Comment on phenotypes: Added '?Abruzzo-Erickson syndrome, 302905' based on OMIM and clinical review that Abruzzo-Erickson syndrome phenotype is clinically relevant. Kept the question-mark because evidence for this gene:disease association is limited (1 family reported in Pauws et al., 2013 (PMID:22784330).

Additional notes from clinical review: An unpublished case presented with IUGR, Microcephaly, hydronephrosis, echogenic kidney, hypoplastic nasal bone. Long bones short and bowed, ambigious genitalia, megalourethra, thickened bladder wall. OMIM phenotypes include IUGR, microcephaly, long bone bowing and agenesis of the corpus callosum (ACC).; Changed rating: GREEN
Fetal anomalies v0.146 IKBKG Rebecca Foulger Added comment: Comment on mode of inheritance: Set mode of inheritance to X-linked dominant after clinical review so that both X-linked dominant and X-linked recessive inheritance would be picked up.
Fetal anomalies v0.134 ELAC2 Rebecca Foulger edited their review of gene: ELAC2: Added comment: This gene and phenotype were reviewed during meetings at Great Ormond Street hospital in March 2019. Clinical review and curation was performed by Lyn Chitty, Anna de Burca, Rhiannon Mellis, Richard Scott, Ellen McDonagh and Rebecca Foulger. Outcome of review: Confirmed that phenotype is fetally-relevant: keep on the Fetal anomalies panel as Green.
