RCV001229113 | SCV001401549 | uncertain significance | Idiopathic generalized epilepsy; Epilepsy, idiopathic generalized, susceptibility to, 13; Epilepsy, childhood absence 4 | 2023-11-15 | criteria provided, single submitter | clinical testing | This sequence change replaces glutamic acid, which is acidic and polar, with glycine, which is neutral and non-polar, at codon 201 of the GABRA1 protein (p.Glu201Gly). This variant is present in population databases (rs765292293, gnomAD 0.002%). 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: 956330). 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 not expected to disrupt GABRA1 protein function with a negative predictive value of 95%. 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. |
