Color Diagnostics, LLC DBA Color Health RCV001179725 SCV001344452 uncertain significance Cardiomyopathy 2023-11-09 criteria provided, single submitter clinical testing This missense variant replaces aspartic acid with valine at codon 2796 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). To our knowledge, functional studies have not been reported for this variant. This variant has been reported in an individual suspected to be affected with dilated cardiomyopathy (PMID: 30847666). 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.
Labcorp Genetics (formerly Invitae), Labcorp RCV001875948 SCV002134309 uncertain significance Arrhythmogenic cardiomyopathy with wooly hair and keratoderma; Arrhythmogenic right ventricular dysplasia 8 2023-11-05 criteria provided, single submitter clinical testing This sequence change replaces aspartic acid, which is acidic and polar, with valine, which is neutral and non-polar, at codon 2796 of the DSP protein (p.Asp2796Val). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with DSP-related conditions. ClinVar contains an entry for this variant (Variation ID: 920770). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be disruptive. 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.
