Fetal anomalies v1.836 CRIPT Arina Puzriakova Tag for-review was removed from gene: CRIPT.
Fetal anomalies v1.836 CRIPT Arina Puzriakova commented on gene: CRIPT: The rating of this gene has been updated following NHS Genomic Medicine Service approval.
Fetal anomalies v1.835 CRIPT Arina Puzriakova Source Expert Review Green was added to CRIPT.
Rating Changed from Amber List (moderate evidence) to Green List (high evidence)
Fetal anomalies v1.727 SCUBE3 Sarah Leigh changed review comment from: Associated with relevant phenotype in OMIM and as probable Gen2Phen gene. At least 5 variants reported in 5 unrelated cases, together with supportive functional and mouse model studies (PMID 33308444).; to: Associated with relevant phenotype in OMIM and as probable Gen2Phen gene. PMID 33308444 reports eight SCUBE variants in nine unrelated families, including eighteen affected members. In vtro studies demonstrated a variable impact of disease-causing variants on transcript processing, protein secretion and function, resulting in dysregulation on bone morphogenetic protein (BMP) signaling and a Scube3−/− mouse showed shared phenotypic features with OMIM:619184. Prenatal growth retardation was evident in 8/11 relevant cases.
Fetal anomalies v1.357 CRIPT Arina Puzriakova Classified gene: CRIPT as Amber List (moderate evidence)
Fetal anomalies v1.357 CRIPT Arina Puzriakova Added comment: Comment on list classification: New gene added by Rhiannon Mellis (GOSH). Following curation and clinical review it has been agreed that the associated phenotype is fetally-relevant and therefore this gene should be promoted to Green at the next GMS panel update (added 'for-review' tag)
Fetal anomalies v1.357 CRIPT Arina Puzriakova Gene: cript has been classified as Amber List (Moderate Evidence).
Fetal anomalies v1.356 CRIPT Arina Puzriakova Tag for-review tag was added to gene: CRIPT.
Fetal anomalies v1.228 CRIPT Rhiannon Mellis gene: CRIPT was added
gene: CRIPT was added to Fetal anomalies. Sources: Expert list
Mode of inheritance for gene: CRIPT was set to BIALLELIC, autosomal or pseudoautosomal
Phenotypes for gene: CRIPT were set to Short stature with microcephaly and distinctive facies, 615789
Review for gene: CRIPT was set to GREEN
Added comment: This gene and phenotype were reviewed during meetings at Great Ormond Street hospital in October 2020. This gene has a Green evidence rating on at least one other related PanelApp panel. Clinical review and curation was performed by Lyn Chitty, Rhiannon Mellis, and Richard Scott. Outcome of review: Confirmed that phenotype is fetally-relevant: add to the Fetal anomalies panel as a Green gene.

Copied from rare multisystem ciliopathies panel:
PMID: 24285566 - Adly et al 2014 - 1 case with index patient with consanguineous Saudi parents and a severe ciliopathy phenotype. He had severe midline cleft lip and palate, microcephaly and choanal atresia. He also had significant eye involvement in the form of severe coloboma, and congenital heart disease (ASD and VSD). He had micropenis. Brain imaging revealed pachygyria and absent corpus callosum. He had abnormal inner ear structures. A splicing mutation was identified in SCLT1 (, NM_144643.2:exon5:c.290+2T>C). This mutation completely abolishes the consensus donor site of exon 5 as confirmed by RTPCR, which showed complete skipping of exon 5 resulting in a frameshift and introduction of a premature stop codon (p.Lys79Valfs*4),

PMID: 28005958 - de Castro-Miró et al 2016 - A cohort of 33 pedigrees affected with a variety of retinal disorders was analysed by WES. 1 case with compound heterozygosity (one missense and one splicing altering mutations) in SCLT1 that segregates with the condition in the family (2 affected siblings). Proposed to be causative of early-onset Retinitis Pigmentosa. SCLT1 is a member of the centrosomal/ciliary protein family.

PMID: 28486600 - Li et al 2017 - report a mouse model with mutated Sclt1 gene. The Sclt1-/- mice exhibit typical ciliopathy phenotypes, including cystic kidney, cleft palate and polydactyly.

PMID: 30425282 - Katagiri et al 2018 - a patient with Senior Løken syndrome and her unaffected parents revealed that the patient had infantile-onset retinal dystrophy and juvenile-onset nephronophthisis. Other systemic abnormalities included hepatic dysfunction, megacystis, mild learning disability, autism, obesity, and hyperinsulinemia. Whole-exome sequencing identified compound heterozygous SCLT1 variants (c.1218 + 3insT and c.1631A > G) in the patient. The unaffected parents were heterozygous for each variant. Transcript analysis using reverse transcription PCR demonstrated that the c.1218 + 3insT variant leads to exon 14 skipping (p.V383_M406del), while the other variant (c.1631A > G) primarily leads to exon 17 skipping (p.D480EfsX11) as well as minor amounts of two transcripts. Immunohistochemical analysis demonstrated that the Sclt1 protein was localized to the distal appendage of the photoreceptor basal body, indicating a ciliary protein.

= 3 cases plus a mouse model and functional evidence that the protein is a ciliary protein.

Fetal anomalies v1.155 MN1 Arina Puzriakova Added comment: Comment on list classification: New gene added by Rhiannon Mellis (GOSH). Multiple unrelated individuals (>20) described with a complex developmental disorder and de novo truncating MN1 variants. This gene will be flagged for review to determine whether the phenotype is fetally-relevant and there is enough evidence to include as Green.

Plausible that some features of the disorder, such as craniofacial abnormalities and structural brain anomalies may be detected prenatally. However based on published clinical descriptions, antenatal history was uneventful in most cases - but reports did include fetal brain anomalies (1), NICU admission (1) and IUGR (2). Similarly, neonatal problems were only reported in a few patients but included respiratory issues (3), abnormal ABR (1), congenital diaphragmatic hernia (1), perinatal hypoxia (1), congenital hypothyroidism (1), hearing impairment (1) and SCBU admission (1) (see Supplementary material in PMID: 31834374)
Fetal anomalies v0.197 SPTBN2 Rebecca Foulger Added comment: Comment on phenotypes: Added more informative phenotype description from OMIM (Spinocerebellar ataxia, autosomal recessive 14, 615386) as Gene2Phenotype names the disorder as SCA14.
