Ambry Genetics | RCV000246983 | SCV000320218 | likely pathogenic | Cardiovascular phenotype | 2015-09-10 | criteria provided, single submitter | clinical testing | The c.1521-1G>A intronic variant results from a G to A substitution one nucleotide upstream from coding exon 11 of the DSC2 gene. This nucleotide position is highly conserved in available vertebrate species. Using the BDGP and ESEfinder splice site prediction tools, this alteration is predicted to abolish the native acceptor site; however, direct evidence is unavailable. Alterations that disrupt the canonical splice site are expected to cause aberrant splicing, resulting in an abnormal protein or a transcript that is subject to nonsense-mediated mRNA decay, and splice and other loss-of-function variants have been previously described in the DSC2 gene (Heuser A, Am J Hum Genet. 2006; 79(6):1081-8). As such, the c.1521-1G>A variant is classified as likely pathogenic. |
