Invitae RCV000641788 SCV000763437 uncertain significance Arrhythmogenic cardiomyopathy with wooly hair and keratoderma; Arrhythmogenic right ventricular dysplasia 8 2021-07-01 criteria provided, single submitter clinical testing 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 has not been reported in the literature in individuals with DSP-related disease. This variant is not present in population databases (ExAC no frequency). This sequence change replaces tryptophan with arginine at codon 2717 of the DSP protein (p.Trp2717Arg). The tryptophan residue is highly conserved and there is a moderate physicochemical difference between tryptophan and arginine.
Color Diagnostics, LLC DBA Color Health RCV001176628 SCV001340664 uncertain significance Cardiomyopathy 2023-08-31 criteria provided, single submitter clinical testing This variant is located in the DSP protein. Computational prediction is inconclusive regarding the impact of this variant on protein structure and function (internally defined REVEL score threshold 0.5 < inconclusive < 0.7, 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 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.
