Color Diagnostics, LLC DBA Color Health RCV001191174 SCV001358879 uncertain significance Cardiomyopathy 2023-09-13 criteria provided, single submitter clinical testing This missense variant replaces tyrosine with cysteine at codon 170 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 cardiovascular disorders in the literature. This variant has been identified in 2/251276 chromosomes 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 RCV001876237 SCV002282626 uncertain significance Arrhythmogenic right ventricular dysplasia 11 2022-02-05 criteria provided, single submitter clinical testing Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Tolerated"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C25"). 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. ClinVar contains an entry for this variant (Variation ID: 927709). This variant has not been reported in the literature in individuals affected with DSC2-related conditions. This variant is present in population databases (rs759910399, gnomAD 0.002%). This sequence change replaces tyrosine, which is neutral and polar, with cysteine, which is neutral and slightly polar, at codon 170 of the DSC2 protein (p.Tyr170Cys).
