Labcorp Genetics (formerly Invitae), Labcorp RCV003801411 SCV004594230 pathogenic Epilepsy, childhood absence, susceptibility to, 1; Epilepsy, childhood absence, susceptibility to, 5 2023-07-27 criteria provided, single submitter clinical testing For these reasons, this variant has been classified as Pathogenic. 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. This missense change has been observed in individual(s) with GABRB3-related conditions (Invitae). 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 alanine, which is neutral and non-polar, with threonine, which is neutral and polar, at codon 273 of the GABRB3 protein (p.Ala273Thr).
