GeneDx RCV000182769 SCV000235155 uncertain significance not provided 2014-04-15 criteria provided, single submitter clinical testing p.Ala2818Val (GCC>GTC): c.8453 C>T in exon 57 of the RYR2 gene (NM_001035.2). The A2818V variant has not been published as a mutation or as a benign polymorphism to our knowledge. The A2818V 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. However, the A2818V variant is a conservative amino acid substitution, which is not likely to impact secondary protein structure as these residues share similar properties. This substitution occurs at a position that is not conserved across species. In silico analysis is inconsistent in its predictions as to whether or not the variant is damaging to the protein structure/function. No missense mutations in nearby residues have been reported in association with arrhythmia and the variant is not located in any of the RYR2 mutation hot spots (Medeiros-Domingo A et al., 2009). 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 ARRHYTHMIA panel(s).
