Labcorp Genetics (formerly Invitae), Labcorp RCV001881468 SCV002152581 uncertain significance Arrhythmogenic cardiomyopathy with wooly hair and keratoderma; Arrhythmogenic right ventricular dysplasia 8 2021-10-12 criteria provided, single submitter clinical testing This sequence change replaces aspartic acid with glutamic acid at codon 1513 of the DSP protein (p.Asp1513Glu). The aspartic acid residue is moderately conserved and there is a small physicochemical difference between aspartic acid and glutamic acid. 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 output the following: SIFT: "Tolerated"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0". The glutamic acid amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. This variant has not been reported in the literature in individuals affected with DSP-related conditions. This variant is not present in population databases (ExAC no frequency).
