GeneDx RCV000182714 SCV000235096 uncertain significance not provided 2014-08-12 criteria provided, single submitter clinical testing p.Glu1189Lys (GAA>AAA): c.3565 G>A in exon 29 of the RYR2 gene (NM_001035.2). The E1189K variant has not been published as a mutation, nor has it been reported as a benign polymorphism to our knowledge. The E1189K variant was not observed in approximately 6,200 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 E1189K 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. Additionally, 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. However, missense mutations in nearby residues have not been reported, indicating this region of the protein may be tolerant of change. Therefore, based on the currently available information, it is unclear whether this variant is a pathogenic mutation or a rare benign variant. The variant is found in ARRHYTHMIA panel(s).
