RCV001185710 | SCV001351963 | uncertain significance | Cardiomyopathy | 2022-05-11 | criteria provided, single submitter | clinical testing | This missense variant replaces glycine with aspartic acid at codon 505 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 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. |
Invitae | RCV001862919 | SCV002209358 | uncertain significance | Arrhythmogenic right ventricular dysplasia 11 | 2021-06-12 | 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 output the following: SIFT: "Deleterious"; PolyPhen-2: "Possibly Damaging"; Align-GVGD: "Class C65". The aspartic acid amino acid residue is found in multiple mammalian species, suggesting that this missense change does not adversely affect protein function. 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 DSC2-related conditions. ClinVar contains an entry for this variant (Variation ID: 924420). This variant is not present in population databases (ExAC no frequency). This sequence change replaces glycine with aspartic acid at codon 505 of the DSC2 protein (p.Gly505Asp). The glycine residue is highly conserved and there is a moderate physicochemical difference between glycine and aspartic acid. |
