| Invitae | RCV000532219 | SCV000645014 | uncertain significance | Arrhythmogenic right ventricular dysplasia 11 | 2023-11-17 | criteria provided, single submitter | clinical testing | This sequence change falls in intron 3 of the DSC2 gene. It does not directly change the encoded amino acid sequence of the DSC2 protein. It affects a nucleotide within the consensus splice site. This variant is present in population databases (no rsID available, gnomAD 0.007%). This variant has not been reported in the literature in individuals affected with DSC2-related conditions. ClinVar contains an entry for this variant (Variation ID: 468382). 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 is not likely to affect RNA splicing. 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. |
| Ambry Genetics | RCV002341375 | SCV002618760 | uncertain significance | Cardiovascular phenotype | 2020-01-06 | criteria provided, single submitter | clinical testing | The c.355-3G>T intronic variant results from a G to T substitution 3 nucleotides upstream from coding exon 4 in the DSC2 gene. This nucleotide position is not well conserved in available vertebrate species. Using the BDGP and ESEfinder splice site prediction tools, this alteration is not predicted to have any deleterious effect on this splice acceptor; however, direct evidence is unavailable. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. |
