Chirag Patel gene: OTUD7A was added gene: OTUD7A was added to Intellectual disability syndromic and non-syndromic. Sources: Literature Mode of inheritance for gene: OTUD7A was set to BIALLELIC, autosomal or pseudoautosomal Publications for gene: OTUD7A were set to PMID: 31997314 Phenotypes for gene: OTUD7A were set to Epileptic encephalopathy, no OMIM# yet Review for gene: OTUD7A was set to RED Added comment: One patient with severe global developmental delay, language impairment and epileptic encephalopathy. Homozygous OTUD7A missense variant (c.697C>T, p.Leu233Phe), predicted to alter an ultraconserved amino acid, lying within the OTU catalytic domain. Its subsequent segregation analysis revealed that the parents, presenting with learning disability, and brother were heterozygous carriers. Biochemical assays demonstrated that proteasome complex formation and function were significantly reduced in patient‐derived fibroblasts and in OTUD7A knockout HAP1 cell line. We provide evidence that biallelic pathogenic OTUD7A variation is linked to early‐onset epileptic encephalopathy and proteasome dysfunction. Gene lies in the chromosome 15q13.3 region. Heterozygous microdeletions of chromosome 15q13.3 show incomplete penetrance and are associated with a highly variable phenotype that may include intellectual disability, epilepsy, facial dysmorphism and digit anomalies.
