GeneDx RCV000182777 SCV000235163 uncertain significance not provided 2013-01-11 criteria provided, single submitter clinical testing p.Tyr3138His (TAT>CAT): c.9412 T>C in exon 66 of the RYR2 gene (NM_001035.2). The Tyr3138His variant in the RYR2 gene has not been reported as a disease-causing mutation or as a benign polymorphism to our knowledge. Tyr3138His results in a non-conservative amino acid substitution of a neutral polar Tyrosine with a positively charged Histidine at a position that is conserved across species. In silico analysis predicts Tyr3138His is probably damaging to the protein structure/function. The NHLBI ESP Exome Variant Server reports Tyr3138His 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. Nevertheless, Tyr3138His does not occur in one of the mutation hot spot regions of the RYR2 gene (Medeiros-Domingo A et al., 2009), and no mutations in nearby codons have been reported in association with arrhythmia. We cannot definitively determine if Tyr3138His is a disease-causing mutation or a rare benign variant. The variant is found in ARVC panel(s).
