Labcorp Genetics (formerly Invitae), Labcorp RCV001996684 SCV002220253 pathogenic not provided 2023-03-18 criteria provided, single submitter clinical testing This sequence change creates a premature translational stop signal (p.Leu10Trpfs*4) in the GJB2 gene. While this is not anticipated to result in nonsense mediated decay, it is expected to disrupt the last 217 amino acid(s) of the GJB2 protein. This variant is present in population databases (no rsID available, gnomAD 0.007%). This premature translational stop signal has been observed in individual(s) with GJB2-related conditions (PMID: 16380907). ClinVar contains an entry for this variant (Variation ID: 1446999). This variant disrupts a region of the GJB2 protein in which other variant(s) (p.Cys211Leufs*5) have been determined to be pathogenic (PMID: 9529365, 12910486, 20863150). This suggests that this is a clinically significant region of the protein, and that variants that disrupt it are likely to be disease-causing. For these reasons, this variant has been classified as Pathogenic.
