GeneDx RCV000213932 SCV000279214 uncertain significance not provided 2016-01-05 criteria provided, single submitter clinical testing The G3657D variant has not been published as a pathogenic variant, nor has it been reported as a benign variant to our knowledge. The G3657D variant was not observed in approximately 5,900 individuals of European and African American ancestry in the NHLBI Exome Sequencing Project, indicating it is not a common benign variant in these populations. The G3657D 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. However, this substitution occurs at a position that is not conserved across species. In silico analysis predicts this variant likely does not alter the protein structure/function. Additionally, no missense variants in nearby residues have been reported in the Human Gene Mutation Database in association with arrhythmia (Stenson et al., 2014), indicating that this region of the gene is not known to harbor disease-causing variants. Finally, the G3657D 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).
