RCV000222161 | SCV000271703 | uncertain significance | not specified | 2015-03-04 | criteria provided, single submitter | clinical testing | The p.Asp350Tyr variant in DSC2 has been reported in 1 Caucasian adult with prob able ARVC (diagnosed upon myocardial biopsy) as well as two siblings with abnorm al ECGs (Bhuiyan 2009). This variant has also been identified in 1/10436 African chromosomes by the Exome Aggregation Consortium (ExAC, http://exac.broadinstitu te.org). Computational prediction tools and conservation analysis suggest that i t may impact the protein, though this information is not predictive enough to de termine pathogenicity. In summary, the clinical significance of the p.Asp350Tyr variant is uncertain. |

RCV001524245 | SCV001734040 | uncertain significance | Cardiomyopathy | 2020-09-15 | criteria provided, single submitter | clinical testing | This missense variant replaces aspartic acid with tyrosine at codon 350 of the DSC2 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 an individual affected with probably arrhythmogenic right ventricular cardiomyopathy as well as two siblings with abnormal ECGs (PMID: 20031616). This variant has also been reported in an individual without a diagnosis of arrhythmogenic right ventricular cardiomyopathy (PMID: 28471438). This variant has been identified in 2/282446 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. |
