Invitae RCV001855964 SCV002201023 uncertain significance Idiopathic generalized epilepsy; Epilepsy, idiopathic generalized, susceptibility to, 13; Epilepsy, childhood absence 4 2022-05-06 criteria provided, single submitter clinical testing This sequence change replaces glycine, which is neutral and non-polar, with arginine, which is basic and polar, at codon 78 of the GABRA1 protein (p.Gly78Arg). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with GABRA1-related conditions. ClinVar contains an entry for this variant (Variation ID: 625850). Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Possibly Damaging"; Align-GVGD: "Class C0"). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may create or strengthen a splice site. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance.
Institute of Human Genetics, University of Goettingen RCV000767857 SCV000864210 uncertain significance Sensorineural hearing loss disorder; Seizure; Intellectual disability 2019-01-09 no assertion criteria provided clinical testing The variant has not been previously described in association with disease, but segregates with the disorder in this family.
