Labcorp Genetics (formerly Invitae), Labcorp RCV002514572 SCV003439308 pathogenic Idiopathic generalized epilepsy; Epilepsy, idiopathic generalized, susceptibility to, 13; Epilepsy, childhood absence 4 2022-11-08 criteria provided, single submitter clinical testing For these reasons, this variant has been classified as Pathogenic. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. Experimental studies have shown that this missense change affects GABRA1 function (PMID: 24623842). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is expected to disrupt GABRA1 protein function. ClinVar contains an entry for this variant (Variation ID: 127073). This missense change has been observed in individual(s) with Dravet syndrome (PMID: 24623842). In at least one individual the variant was observed to be de novo. This variant is not present in population databases (gnomAD no frequency). This sequence change replaces glycine, which is neutral and non-polar, with serine, which is neutral and polar, at codon 251 of the GABRA1 protein (p.Gly251Ser).
