GeneDx RCV000182829 SCV000235216 uncertain significance not provided 2014-07-14 criteria provided, single submitter clinical testing This variant is denoted c.13057 C>T p.Pro4353Ser (P4353S) NM_001035.2. The P4353S variant has not been published as a mutation or as a benign polymorphism to our knowledge. The P4353S variant was not observed in approximately 6,000 individuals of European and African American ancestry in the NHLBI Exome Sequencing Project, indicating it is not a common benign variant in these populations. In addition, the P4353S 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. Nevertheless, this substitution occurs at a position that is not conserved across species. Moreover, in silico analysis predicts this variant likely does not alter the protein structure/function. Furthermore, no missense mutations in nearby residues have been reported in association with cardiomyopathy, 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).
