RCV001934270 | SCV002215014 | uncertain significance | Arrhythmogenic right ventricular dysplasia 10 | 2023-07-07 | criteria provided, single submitter | clinical testing | This sequence change affects codon 27 of the DSG2 mRNA. It is a 'silent' change, meaning that it does not change the encoded amino acid sequence of the DSG2 protein. This variant also falls at the last nucleotide of exon 2, which is part of the consensus splice site for this exon. This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with DSG2-related conditions. ClinVar contains an entry for this variant (Variation ID: 1438399). Variants that disrupt the consensus splice site are a relatively common cause of aberrant splicing (PMID: 17576681, 9536098). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. 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. |

RCV004010950 | SCV004826074 | uncertain significance | Arrhythmogenic right ventricular cardiomyopathy | 2023-05-16 | criteria provided, single submitter | clinical testing | This variant is located in the DSG2 protein. To our knowledge, functional studies have not been reported for this variant. This variant has not been reported in individuals affected with DSG2-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. |
