Invitae RCV001365526 SCV001561799 uncertain significance Atrial standstill 1; Atrial fibrillation, familial, 11 2022-10-17 criteria provided, single submitter clinical testing 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. This variant has not been reported in the literature in individuals affected with GJA5-related conditions. This variant is present in population databases (no rsID available, gnomAD 0.006%). This sequence change creates a premature translational stop signal (p.Arg342*) in the GJA5 gene. While this is not anticipated to result in nonsense mediated decay, it is expected to disrupt the last 17 amino acid(s) of the GJA5 protein. Experimental studies and prediction algorithms are not available or were not evaluated, and the functional significance of this variant is currently unknown. ClinVar contains an entry for this variant (Variation ID: 1056660).
GeneDx RCV001751722 SCV002005002 uncertain significance not provided 2019-08-08 criteria provided, single submitter clinical testing Has not been previously published as pathogenic or benign to our knowledge; Not observed at a significant frequency in large population cohorts (Lek et al., 2016); Nonsense variant predicted to result in protein truncation; however, no loss-of-function variants have been reported downstream of this position in the protein (Stenson et al., 2014)
