Ambry Genetics | RCV000251340 | SCV000318241 | uncertain significance | Cardiovascular phenotype | 2013-02-18 | criteria provided, single submitter | clinical testing | ​The p.V79G variant (also known as c.236T>G) is located in coding exon 3 of the DSC2 gene. This alteration results from a T to G substitution at nucleotide position 236. The valine at codon 79 is replaced by glycine, an amino acid with dissimilar properties. This variant was observed with a PKP2 truncating alteration in a proband tested by our laboratory who is affected with sudden cardiac arrest, syncope and arrhythmia. This variant was not reported in population-based cohorts in the following databases: Database of Single Nucleotide Polymorphisms (dbSNP), NHLBI Exome Sequencing Project (ESP) and 1000 Genomes Project. Based on protein sequence alignment, this amino acid position is well conserved in available vertebrate species. In addition, the in silico prediction for this alteration is inconclusive. Since supporting evidence is limited at this time, the clinical significance of p.V79G remains unclear. |
