GeneDx RCV000182873 SCV000235261 uncertain significance not provided 2018-02-07 criteria provided, single submitter clinical testing This variant is denoted c.6523 A>G at the cDNA level or p.Met2175Val (M2175V) at the protein level. The Met2175Val variant in the RYR2 gene has not been reported previously as a disease-causing mutation or as a benign polymorphism, to our knowledge. Met2175Val results in a conservative amino acid substitution of one non-polar amino acid for another. Although the Met2175 residue is conserved across species, it is not located in a mutation hot spot region of the RYR2 gene. In silico analysis predicts Met2175Val to be possibly damaging to protein structure or function (Adzhubei et al. 2010; Kumar et al. 2009; Schwarz et al. 2011). The NHLBI ESP Exome Variant Server reports Met2175Val was not observed in approximately 5,000 samples from individual of European and African American backgrounds, indicating it is not a common benign variant in these populations. In summary, with the clinical and molecular information available at this time, we cannot determine if the Met2175Val variant is a disease-causing mutation or a benign variant. The variant is found in CPVT panel(s).
