RCV003581953 | SCV004245013 | pathogenic | Charcot-Marie-Tooth Neuropathy X | 2023-05-23 | criteria provided, single submitter | clinical testing | For these reasons, this variant has been classified as Pathogenic. This variant disrupts a region of the GJB1 protein in which other variant(s) (p.Arg220*) have been determined to be pathogenic (PMID: 7477983, 8162049, 9364054, 21291455). 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 GJB1-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change creates a premature translational stop signal (p.Asp169Glufs*27) in the GJB1 gene. While this is not anticipated to result in nonsense mediated decay, it is expected to disrupt the last 115 amino acid(s) of the GJB1 protein. |
