| Intellectual disability syndromic and non-syndromic v0.2525 | CACNB4 |
Bryony Thompson gene: CACNB4 was added gene: CACNB4 was added to Intellectual disability syndromic and non-syndromic. Sources: Literature Mode of inheritance for gene: CACNB4 was set to BIALLELIC, autosomal or pseudoautosomal Publications for gene: CACNB4 were set to 32176688 Phenotypes for gene: CACNB4 were set to intellectual disability; psychomotor retardation; blindness; epilepsy; movement disorder; cerebellar atrophy Review for gene: CACNB4 was set to AMBER Added comment: A homozygous missense variant (Leu126Pro) was identified in two siblings with intellectual disability, psychomotor retardation, blindness, epilepsy, movement disorder and cerebellar atrophy. In vitro functional assays of the variant identify three potential pathomechanisms: impairs the formation of synaptic P/Q-type calcium channel complexes; prevents activity-dependent nuclear targeting and thus β4-dependent nuclear functions; disturbs complex formation between β4b and the TRAF2 and NCK interacting kinase TNIK.

| Intellectual disability syndromic and non-syndromic v0.1298 | SMARCC2 |
Chirag Patel gene: SMARCC2 was added gene: SMARCC2 was added to Intellectual disability, syndromic and non-syndromic_GHQ_VCGS. Sources: Literature Mode of inheritance for gene: SMARCC2 was set to MONOALLELIC, autosomal or pseudoautosomal, NOT imprinted Publications for gene: SMARCC2 were set to PMID: 30580808 Phenotypes for gene: SMARCC2 were set to Coffin-Siris syndrome 8; OMIM #618362 Review for gene: SMARCC2 was set to GREEN Added comment: 15 individuals with variable degrees of neurodevelopmental delay, growth retardation, prominent speech impairment, hypotonia, feeding difficulties, behavioral abnormalities, and dysmorphic features. They found heterozygous de novo SMARCC2 variants, but no functional evidence of specific variants. Transcriptomic analysis of fibroblasts from affected individuals highlighted a group of differentially expressed genes with possible roles in regulation of neuronal development and function, namely H19, SCRG1, RELN, and CACNB4.
