GeneDx RCV000182738 SCV000235122 uncertain significance not provided 2012-01-10 criteria provided, single submitter clinical testing This variant is denoted c.5836 G>A at the cDNA level or p.Glu1946Lys (E1946K) at the protein level. The Glu1946Lys variant in the RYR2 gene has not been reported previously as a disease-causing mutation or as a benign polymorphism, to our knowledge. Glu1946Lys results in a non-conservative amino acid substitution of a negatively charged Glutamic acid with a positively charged Lysine at a residue that is conserved across species. The Glu1946Lys variant was not detected in up to 600 alleles from control individuals of Caucasian and African American ancestry tested at GeneDx. The NHLBI ESP Exome Variant Server reports Glu1946Lys was not observed in approximately 4,500 samples from individuals of European and African American backgrounds. However, no disease-causing mutations have been reported in surrounding residues and Glu1946Lys is not located within any of the three mutation hot spot regions in the RYR2 gene. In summary, with the clinical and molecular information available at this time, the clinical significance of the Glu1946Lys variant in the RYR2 gene remains unknown. The variant is found in CPVT panel(s).
