Achchuthan Shanmugasundram gene: SNF8 was added gene: SNF8 was added to Optic neuropathy. Sources: Literature Mode of inheritance for gene: SNF8 was set to BIALLELIC, autosomal or pseudoautosomal Publications for gene: SNF8 were set to 38423010 Phenotypes for gene: SNF8 were set to neurodevelopmental disorder, MONDO:0700092; optic atrophy, MONDO:0003608 Review for gene: SNF8 was set to AMBER Added comment: PMID:38423010 reported nine individuals from six families presenting with a spectrum of neurodevelopmental/ neurodegenerative features caused by biallelic variants in SNF8. The phenotypic spectrum included four individuals with severe developmental and epileptic encephalopathy with leukoencephalopathy and early death in three of those cases. Two individuals died too young to develop epilepsy. A second cohort shows a milder phenotype with intellectual disability, childhood-onset optic atrophy, or ataxia. All mildly affected individuals shared the same hypomorphic variant, c.304G>A (p.Val102Ile) as compound heterozygous. Three of the patients (from two families) with the milder phenotype also have optic atrophy. Functional studies using fibroblasts derived from patients and zebrafish model showed loss of function as the disease mechanism. This gene has not yet been associated with any phenotypes either in OMIM or in Gene2Phenotype. Sources: Literature |
