Color Diagnostics, LLC DBA Color Health RCV001191764 SCV001359663 uncertain significance Cardiomyopathy 2023-02-08 criteria provided, single submitter clinical testing This missense variant replaces tyrosine with serine at codon 167 of the DSC2 protein. Computational prediction suggests that this variant may not impact protein structure and function (internally defined REVEL score threshold <= 0.5, PMID: 27666373). To our knowledge, functional studies have not been reported for this variant. This variant has not been reported in individuals affected with DSC2-related disorders in the literature. This variant has not been identified in the general population by the Genome Aggregation Database (gnomAD). The available evidence is insufficient to determine the role of this variant in disease conclusively. Therefore, this variant is classified as a Variant of Uncertain Significance.
Invitae RCV003517303 SCV004354082 uncertain significance Arrhythmogenic right ventricular dysplasia 11 2024-01-11 criteria provided, single submitter clinical testing This sequence change replaces tyrosine, which is neutral and polar, with serine, which is neutral and polar, at codon 167 of the DSC2 protein (p.Tyr167Ser). 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: 916449). 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 with a positive predictive value of 80%. 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.
