GeneDx RCV000255613 SCV000322024 likely pathogenic not provided 2015-07-07 criteria provided, single submitter clinical testing The S4583Y variant that is likely pathogenic has not been published as a pathogenic variant, nor has it been reported as a benign polymorphism to our knowledge. The S4583Y variant was not observed in approximately 6300 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 S4583Y variant is a semi-conservative amino acid substitution, which may impact secondary protein structure as these residues differ in some properties. This substitution occurs at a position that is conserved across species. In silico analysis predicts this variant is probably damaging to the protein structure/function. Missense variants in nearby residues (H4579Y, I4587V) have been reported in the Human Gene Mutation Database in association with CPVT (Stenson et al., 2014), supporting the functional importance of this region of the protein. Finally, the S4583Y variant is located in one of the three hot-spot regions of the RYR2 gene, where the majority of pathogenic missense variatns occur (Medeiros-Domingo et al., 2009). Therefore, this variant is a strong candidate for a pathogenic variant, however the possibility that it is a benign variant cannot be excluded.
