GeneDx RCV000414323 SCV000491834 uncertain significance not specified 2016-11-18 criteria provided, single submitter clinical testing A variant of uncertain significance has been identified in the RYR2 gene. The L1505V variant has not been published as a pathogenic variant, nor has it been reported as a benign variant to our knowledge. This variant was not observed in approximately 6,300 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 L1505V variant is a conservative amino acid substitution, which is not likely to impact secondary protein structure as these residues share similar properties. In addition, the L1505V variant is not located in one of the three hot-spot regions of the RYR2 gene, where the majority of pathogenic missense variants occur (Medeiros-Domingo et al., 2009). Furthermore, in silico analysis is inconsistent in its predictions as to whether or not the variant is damaging to the protein structure/function.Therefore, based on the currently available information, it is unclear whether this variant is pathogenic or benign.
