Invitae RCV000525849 SCV000641342 uncertain significance Arrhythmogenic cardiomyopathy with wooly hair and keratoderma; Arrhythmogenic right ventricular dysplasia 8 2017-03-26 criteria provided, single submitter clinical testing In summary, this variant is a novel missense change with uncertain impact on protein function. It has been classified as a Variant of Uncertain Significance. Algorithms developed to predict the effect of missense changes on protein structure and function do not agree on the potential impact of this missense change (SIFT: "Tolerated"; PolyPhen-2: "Possibly Damaging"; Align-GVGD: "Class C0"). This variant is not present in population databases (ExAC no frequency) and has not been reported in the literature in individuals with a DSP-related disease. This sequence change replaces lysine with asparagine at codon 2435 of the DSP protein (p.Lys2435Asn). The lysine residue is moderately conserved and there is a moderate physicochemical difference between lysine and asparagine.
Color Diagnostics, LLC DBA Color Health RCV001186302 SCV001352685 uncertain significance Cardiomyopathy 2020-03-03 criteria provided, single submitter clinical testing This missense variant replaces lysine with asparagine at codon 2435 of the DSP protein. Computational prediction suggests that this variant may not impact protein structure and function (internally defined REVEL score threshold <= 0.5, PMID: 27666373). Splice site prediction tools suggest that this variant may not impact RNA splicing. 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.
