GeneDx RCV000182882 SCV000235270 uncertain significance not provided 2016-12-07 criteria provided, single submitter clinical testing p.Lys3054Arg (AAA>AGA): c.9161 A>G in exon 65 of the RYR2 gene (NM_001035.2). The K3054R variant has not been published as a mutation, nor has it been reported as a benign polymorphism to our knowledge. The K3054R 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. This substitution occurs at a position that is conserved across species. However, the K3054R variant is a conservative amino acid substitution, which is not likely to impact secondary protein structure as these residues share similar properties. In silico analysis predicts this variant likely does not alter the protein structure/function. Furthermore, no missense mutations in nearby residues have been reported, indicating that 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).
