Laboratory for Molecular Medicine, Mass General Brigham Personalized Medicine RCV000220729 SCV000271737 uncertain significance not specified 2015-06-11 criteria provided, single submitter clinical testing The p.Ala2092Val variant in DSP has not been previously reported in individuals with cardiomyopathy or in large population studies. Computational prediction too ls and conservation analysis suggest that this variant may impact the protein, t hough this information is not predictive enough to determine pathogenicity. In s ummary, the clinical significance of the p.Ala2092Val variant is uncertain.
Mayo Clinic Laboratories, Mayo Clinic RCV001509262 SCV001715875 uncertain significance not provided 2019-07-08 criteria provided, single submitter clinical testing
Color Diagnostics, LLC DBA Color Health RCV001804950 SCV002053374 uncertain significance Cardiomyopathy 2023-02-28 criteria provided, single submitter clinical testing This missense variant replaces alanine with valine at codon 2092 of 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 been reported in one individual affected with primary electrical disease in the literature (PMID: 28341588). This variant has been identified in 1/251428 chromosomes 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 RCV002517545 SCV003455680 uncertain significance Arrhythmogenic cardiomyopathy with wooly hair and keratoderma; Arrhythmogenic right ventricular dysplasia 8 2022-05-28 criteria provided, single submitter clinical testing This sequence change replaces alanine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 2092 of the DSP protein (p.Ala2092Val). This variant is present in population databases (no rsID available, gnomAD 0.002%). 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: 228645). 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. 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.
