Labcorp Genetics (formerly Invitae), Labcorp RCV002815084 SCV003203200 uncertain significance Epilepsy, childhood absence, susceptibility to, 1; Epilepsy, childhood absence, susceptibility to, 5 2022-05-25 criteria provided, single submitter clinical testing This sequence change replaces tyrosine, which is neutral and polar, with serine, which is neutral and polar, at codon 467 of the GABRB3 protein (p.Tyr467Ser). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with GABRB3-related conditions. 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 GABRB3 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.
