Labcorp Genetics (formerly Invitae), Labcorp RCV003801566 SCV004595052 pathogenic Epilepsy, childhood absence 2; Febrile seizures, familial, 8 2023-05-01 criteria provided, single submitter clinical testing For these reasons, this variant has been classified as Pathogenic. This variant disrupts a region of the GABRG2 protein in which other variant(s) (p.Trp429*) have been determined to be pathogenic (PMID: 18566737). This suggests that this is a clinically significant region of the protein, and that variants that disrupt it are likely to be disease-causing. This variant has not been reported in the literature in individuals affected with GABRG2-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change creates a premature translational stop signal (p.Asn393Lysfs*10) in the GABRG2 gene. While this is not anticipated to result in nonsense mediated decay, it is expected to disrupt the last 75 amino acid(s) of the GABRG2 protein.
