Invitae RCV001870782 SCV002132017 uncertain significance Arrhythmogenic right ventricular dysplasia 11 2021-02-03 criteria provided, single submitter clinical testing This variant has not been reported in the literature in individuals with DSC2-related conditions. 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. 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, but these predictions have not been confirmed by published functional studies and their clinical significance is uncertain. This variant is not present in population databases (ExAC no frequency). This sequence change replaces proline with alanine at codon 241 of the DSC2 protein (p.Pro241Ala). The proline residue is highly conserved and there is a small physicochemical difference between proline and alanine.
