| Intellectual disability syndromic and non-syndromic v0.5549 | SMARCA4 |
Claire Fryer-Smith changed review comment from: Coffin-Siris syndrome is a congenital malformation syndrome characterized by developmental delay, intellectual disability, coarse facial features, feeding difficulties, and hypoplastic or absent fifth fingernails and fifth distal phalanges. Missense and an in-frame deletion in SCARCA4 have been observed across 15 CSS patients in the literature (22426308, 23637025, 23929686), suggesting a dominant negative GoF effect. LoF variants in SMARCA4 result in Rhabdoid tumor predisposition syndrome, which does not exhibit ID.; to: Coffin-Siris syndrome is a congenital malformation syndrome characterized by developmental delay, intellectual disability, coarse facial features, feeding difficulties, and hypoplastic or absent fifth fingernails and fifth distal phalanges.

| Intellectual disability syndromic and non-syndromic v0.5198 | CRIPT |
Karina Sandoval commented on gene: CRIPT: PMID: 37013901 identified 6 individuals with Rothmund-Thomson syndrome characterised by poikiloderma, sparse hair, small stature, skeletal defects, cancer, cataracts, resembling features of premature aging. Two new variants identified and 4 were already published. 5 were hom, 1 was chet, all with different variants. All CRIPT individuals fulfilled the diagnostic criteria for RTS, and additionally had neurodevelopmental delay and seizures. CRIPT-deficient fibroblasts showed an unremarkable mitotic progression and unremarkable number of mitotic errors, c.132del p.(Ala45Glyfs*82), hom c.227G>A, p.(Cys76Tyr), hom c.133_134insGG,p.(Ala45Glyfs*82),hom c.141del p.(Phe47Leufs*84), hom c.8G>A p.(Cys3Tyr), 1,331 bp del exon 1, chet c.7_8del; p.(Cys3Argfs*4), hom |

All individuals had global developmental delay and intellectual disability. Consistent facial dysmorphisms included coarse facies, prominent forehead, board depressed nasal root, tented mouth, long smooth philtrum, and low-set ears. In vitro studies of missense variants demonstrated accelerated protein degradation via the autophagy-lysosomal pathway, while analysis of primary fibroblasts and granulocytes provided functional evidence of ER and nuclear envelope dysfunction.

Konstantinos Varvagiannis gene: CDC42BPB was added gene: CDC42BPB was added to Intellectual disability syndromic and non-syndromic. Sources: Literature Mode of inheritance for gene: CDC42BPB was set to MONOALLELIC, autosomal or pseudoautosomal, imprinted status unknown Publications for gene: CDC42BPB were set to 32031333 Phenotypes for gene: CDC42BPB were set to Central hypotonia; Global developmental delay; Intellectual disability; Seizures; Autistic behavior; Behavioral abnormality Penetrance for gene: CDC42BPB were set to unknown Review for gene: CDC42BPB was set to GREEN Added comment: Chilton et al (2020 - PMID: 32031333) report on 14 individuals with missense and loss-of-function CDC42BPB variants. Features included hypotonia (8/11), DD (12/13 - the 14th was a fetus), ID (7/13), ASD (8/12), clinical seizures (in 3 - a 4th had abnormal EEG without seizures), behavioral abnormalities. Variable non-specific dysmorphic features were reported in some (sparse hair being the most frequent - 4/8). Additional features were observed in few (=<4) incl. cryptorchidism, ophthalmological issues, constipation, kidney abnormalities, micropenis, etc. All individuals had non-diagnostic prior genetic testing (incl. CMA, FMR1, MECP2, Angelman/Prader-Willi methylation studies, autism gene panel - suggesting relevance to the current panel) or metabolic testing. Variants were identified following clinical exome sequencing with Sanger confirmation. Most occurred as de novo events (11/14) while inheritance was not available for few (3/14). Missense variants did not display (particular) clustering. Almost all variants were absent from gnomAD and were predicted to be deleterious in silico (among others almost all had CADD scores >25). As the authors comment, CDC42BPB encodes myotonic dystrophy-related Cdc42-binding kinase β (MRCKβ) a serine/threonine protein kinase playing a role in regulation of cytoskeletal reorganization and cell migration in nonmuscle cells (through phosporylation of MLC2). Previous studies have demonstrated that it is ubiquitously expressed with prenatal brain expression. The gene appears to be intolerant to pLoF (pLI of 1) as well as to missense variants (Z-score of 3.66). CDC42BPB is a downstream effector of CDC42. Mutations of the latter cause Takenouchi-Kosaki syndrome with DD/ID and some further overlapping features (with CDC42BPB-associated phenotypes). Homozygous Cdc42bpb KO in mouse appears to be nonviable (MGI:2136459). Loss of gek in the eyes of Drosophila results in disrupted growth cone targeting to the lamina (gek is the fly CDC42BPB ortholog). Please consider inclusion with amber / green rating in the ID panel (>=4 relevant individuals / variants) and other panels (e.g. for epilepsy, ASD). Sources: Literature |
