Labcorp Genetics (formerly Invitae), Labcorp RCV003793992 SCV004582663 uncertain significance Atrial standstill 1; Atrial fibrillation, familial, 11 2023-12-01 criteria provided, single submitter clinical testing This sequence change results in a frameshift in the GJA5 gene (p.Ser260Alafs*124). While this is not anticipated to result in nonsense mediated decay, it is expected to disrupt the last 99 amino acid(s) of the GJA5 protein and extend the protein by 24 additional amino acid residues. This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with GJA5-related conditions. Experimental studies and prediction algorithms are not available or were not evaluated, and the functional significance of this variant is currently unknown. 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.
