Invitae RCV001052173 SCV001216370 uncertain significance Arrhythmogenic cardiomyopathy with wooly hair and keratoderma; Arrhythmogenic right ventricular dysplasia 8 2021-08-28 criteria provided, single submitter clinical testing This sequence change replaces threonine with lysine at codon 634 of the DSP protein (p.Thr634Lys). The threonine residue is moderately conserved and there is a moderate physicochemical difference between threonine and lysine. This variant is present in population databases (rs139964486, ExAC 0.01%). This variant has not been reported in the literature in individuals affected with DSP-related conditions. 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 tolerated. 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.
