Laboratory for Molecular Medicine, Mass General Brigham Personalized Medicine RCV000217409 SCV000271705 uncertain significance not specified 2015-03-24 criteria provided, single submitter clinical testing The p.Leu195Ser variant in DSC2 has not been previously reported in individuals with cardiomyopathy and was absent from large population studies. Computational prediction tools and conservation analyses do not provide strong support for or against an impact to the protein. In summary, the clinical significance of the p .Leu195Ser variant is uncertain.
GeneDx RCV002508200 SCV002817705 uncertain significance not provided 2022-07-01 criteria provided, single submitter clinical testing Not observed at significant frequency in large population cohorts (gnomAD); In silico analysis supports that this missense variant has a deleterious effect on protein structure/function; Has not been previously published as pathogenic or benign to our knowledge
Invitae RCV003114380 SCV003784193 uncertain significance Arrhythmogenic right ventricular dysplasia 11 2023-10-11 criteria provided, single submitter clinical testing This sequence change replaces leucine, which is neutral and non-polar, with serine, which is neutral and polar, at codon 195 of the DSC2 protein (p.Leu195Ser). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with DSC2-related conditions. ClinVar contains an entry for this variant (Variation ID: 228622). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is expected to disrupt DSC2 protein function. 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.
