GeneDx RCV000181175 SCV000233452 uncertain significance not provided 2014-08-29 criteria provided, single submitter clinical testing p.Val119Asp (GTC>GAC): c.356 T>A in exon 4 of the DSC2 gene (NM_024422.3). A variant of unknown significance has been identified in the DSC2 gene. The V119D variant has not been published as a mutation, nor has it been reported as a benign polymorphism to our knowledge. The V119D variant was not observed in approximately 6,500 individuals of European and African American ancestry in the NHLBI Exome Sequencing Project, indicating it is not a common benign variant in these populations. The V119D variant is a non-conservative amino acid substitution, which is likely to impact secondary protein structure as these residues differ in polarity, charge, size and/or other properties. Additionally, this substitution occurs at a position that is class conserved among mammals. However, in silico analysis is inconsistent in its predictions as to whether or not the variant is damaging to the protein structure/function. Furthermore, no mutations in nearby residues have been reported in association with ARVC, indicating this region of the protein may be tolerant of change. Therefore, based on the currently available information, it is unclear whether this variant is a pathogenic mutation or a rare benign variant. The variant is found in CARDIOMYOPATHY panel(s).
