Labcorp Genetics (formerly Invitae), Labcorp RCV001771936 SCV000814485 pathogenic not provided 2022-06-04 criteria provided, single submitter clinical testing For these reasons, this variant has been classified as Pathogenic. This variant disrupts the p.Asp197 amino acid residue in SCN5A. Other variant(s) that disrupt this residue have been determined to be pathogenic (PMID: 31477192; Invitae). This suggests that this residue is clinically significant, and that variants that disrupt this residue are likely to be disease-causing. Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be disruptive. ClinVar contains an entry for this variant (Variation ID: 566986). This missense change has been observed in individual(s) with clinical features of SCN5A-related conditions (Invitae). In at least one individual the variant was observed to be de novo. This variant is not present in population databases (gnomAD no frequency). This sequence change replaces aspartic acid, which is acidic and polar, with glycine, which is neutral and non-polar, at codon 197 of the SCN5A protein (p.Asp197Gly).
GeneDx RCV001771936 SCV001994013 uncertain significance not provided 2019-07-02 criteria provided, single submitter clinical testing Has not been previously published as pathogenic or benign to our knowledge; Reported in ClinVar but additional evidence is not available (ClinVar Variant ID# 566986; Landrum et al., 2016); Not observed in large population cohorts (Lek et al., 2016); In silico analysis, which includes protein predictors and evolutionary conservation, supports a deleterious effect
