Chirag Patel gene: GABRA5 was added gene: GABRA5 was added to Intellectual disability, syndromic and non-syndromic_GHQ_VCGS. Sources: Literature Mode of inheritance for gene: GABRA5 was set to MONOALLELIC, autosomal or pseudoautosomal, NOT imprinted Publications for gene: GABRA5 were set to PMID: 31056671; 29961870 Phenotypes for gene: GABRA5 were set to Epileptic encephalopathy, early infantile, 79; OMIM #618559 Review for gene: GABRA5 was set to GREEN Added comment: 3 unrelated patients with de novo heterozygous missense mutations in GABRA5 gene. In vitro functional expression studies in HEK293 cells showed that the mutant subunit was expressed at the surface and incorporated into the channel, but the mutant channel was 10 times more sensitive to GABA compared to wildtype. This increased sensitization resulted in increased receptor desensitization to GABA, with a reduced maximal GABA-evoked current and impaired capacity to pass GABAergic chloride current.
