Ambry Genetics RCV000621658 SCV000738176 uncertain significance Cardiovascular phenotype 2017-09-15 criteria provided, single submitter clinical testing The p.E782K variant (also known as c.2344G>A), located in coding exon 15 of the DSC2 gene, results from a G to A substitution at nucleotide position 2344. The glutamic acid at codon 782 is replaced by lysine, an amino acid with similar properties. This amino acid position is well conserved in available vertebrate species. In addition, this alteration is predicted to be tolerated by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear.
Color Diagnostics, LLC DBA Color Health RCV000772663 SCV000905922 uncertain significance Cardiomyopathy 2023-06-14 criteria provided, single submitter clinical testing This missense variant replaces glutamic acid with lysine at codon 782 of the DSC2 protein. Computational prediction suggests that this variant may not impact protein structure and function (internally defined REVEL score threshold <= 0.5, PMID: 27666373). To our knowledge, functional studies have not been reported for this variant. This variant has not been reported in individuals affected with DSC2-related 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.
Invitae RCV001868115 SCV002123780 uncertain significance Arrhythmogenic right ventricular dysplasia 11 2023-11-27 criteria provided, single submitter clinical testing This sequence change replaces glutamic acid, which is acidic and polar, with lysine, which is basic and polar, at codon 782 of the DSC2 protein (p.Glu782Lys). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with DSC2-related conditions. ClinVar contains an entry for this variant (Variation ID: 519515). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is expected to disrupt DSC2 protein function with a positive predictive value of 80%. 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.
