Labcorp Genetics (formerly Invitae), Labcorp RCV001881188 SCV002143130 uncertain significance Idiopathic generalized epilepsy; Epilepsy, idiopathic generalized, susceptibility to, 13; Epilepsy, childhood absence 4 2023-10-12 criteria provided, single submitter clinical testing This sequence change replaces valine, which is neutral and non-polar, with methionine, which is neutral and non-polar, at codon 319 of the GABRA1 protein (p.Val319Met). 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: 1378537). 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. 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.
