GeneDx RCV000441089 SCV000535283 uncertain significance not provided 2016-12-22 criteria provided, single submitter clinical testing The L4769S variant of uncertain significance in the RYR2 gene has not been published as a pathogenic variant, nor has it been reported as a benign variant to our knowledge. L4769S was not observed in approximately 6,000 individuals of European and African American ancestry in the NHLBI Exome Sequencing Project, nor was it observed in the Exome Aggregation Consortium, indicating it is not a common benign variant in these populations. The L4769S 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. Moreover, this substitution occurs at a position that is conserved across species, and in silico analysis predicts this variant is probably damaging to the protein structure/function. L4769S is also 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).
