GeneDx RCV000182812 SCV000235198 likely pathogenic not provided 2012-12-03 criteria provided, single submitter clinical testing p.Gly4095Ser (GGC>AGC): c.12283 G>A in exon 90 of the RYR2 gene (NM_001035.2). The Gly4095Ser variant in the RYR2 gene has not been reported as a disease-causing mutation or as a benign polymorphism to our knowledge. Gly4095Ser results in a non-conservative amino acid substitution of a non-polar Glycine with a polar Serine at a position that is conserved across species, and it is located in a mutation hot spot" in the RYR2 gene (Medeiros-Domingo A et al., 2009). Mutations in nearby residues (Ala4091Thr, Ala4091Val, Asn4097Ser) have been reported in association with CPVT, further supporting the functional importance of this region of the protein. In silico analysis predicts Gly4095Ser is probably damaging to the protein structure/function. Furthermore, the NHLBI ESP Exome Variant Server reports Gly4095Ser was not observed in approximately 6,000 samples from individuals of European and African American backgrounds, indicating it is not a common benign variant in these populations. In summary, while Gly4095Ser is a good candidate for a disease-causing mutation, we cannot unequivocally determine the clinical significance of this variant. The variant is found in ARVC panel(s)."
