RCV001181175 | SCV001346272 | uncertain significance | Cardiomyopathy | 2018-12-19 | criteria provided, single submitter | clinical testing | Variant of Uncertain Significance due to insufficient evidence: This missense variant is located in the extracellular cadherin domain 1 of the DSG2 protein. Computational prediction tools and conservation analyses are inconclusive regarding the impact of this variant on the protein function. Computational splicing tools suggest that this variant may not impact RNA splicing. To our knowledge, functional assays have not been performed for this variant nor has this variant been reported in individuals affected with cardiovascular disorders in the literature. This variant is rare in the general population and has been identified in 0/277264 chromosomes by the Genome Aggregation Database (gnomAD). Available evidence is insufficient to determine the role of this variant in disease conclusively. |

RCV001207058 | SCV001378397 | uncertain significance | Arrhythmogenic right ventricular dysplasia 10 | 2021-09-01 | criteria provided, single submitter | clinical testing | This sequence change replaces proline with serine at codon 123 of the DSG2 protein (p.Pro123Ser). The proline residue is highly conserved and there is a moderate physicochemical difference between proline and serine. This variant is not present in population databases (ExAC no frequency). This variant has not been reported in the literature in individuals affected with DSG2-related conditions. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Tolerated"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). 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. |
