| Invitae | RCV001920082 | SCV002161420 | uncertain significance | Arrhythmogenic right ventricular dysplasia 11 | 2023-09-03 | criteria provided, single submitter | clinical testing | This variant has not been reported in the literature in individuals affected with DSC2-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change replaces isoleucine, which is neutral and non-polar, with threonine, which is neutral and polar, at codon 475 of the DSC2 protein (p.Ile475Thr). ClinVar contains an entry for this variant (Variation ID: 1396941). 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. 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 not expected to disrupt DSC2 protein function. |
| Ambry Genetics | RCV002388789 | SCV002697387 | likely benign | Cardiovascular phenotype | 2024-03-11 | criteria provided, single submitter | clinical testing | This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. |

RCV004010803 | SCV004821684 | uncertain significance | Familial isolated arrhythmogenic right ventricular dysplasia | 2023-02-24 | criteria provided, single submitter | clinical testing | This missense variant replaces isoleucine with threonine at codon 475 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. |
