Genes affected

RYR2 (HGNC:10484): (ryanodine receptor 2) This gene encodes a ryanodine receptor found in cardiac muscle sarcoplasmic reticulum. The encoded protein is one of the components of a calcium channel, composed of a tetramer of the ryanodine receptor proteins and a tetramer of FK506 binding protein 1B proteins, that supplies calcium to cardiac muscle. Mutations in this gene are associated with stress-induced polymorphic ventricular tachycardia and arrhythmogenic right ventricular dysplasia. [provided by RefSeq, Jul 2008]

p.Ile3029Val (ATT>GTT): c.9085 A>G in exon 64 of the RYR2 gene (NM_001035.2). The Ile3029Val variant in the RYR2 gene has not been reported as a disease-causing mutation or as a benign polymorphism to our knowledge. Ile3029Val results in a conservative amino acid substitution of one non-polar amino acid with another at a position that is conserved across species. The Ile3029Val variant was not observed with any significant frequency in approximately 6,000 individuals of European and African American ancestry in the NHLBI Exome Sequencing Project. However, in silico analysis predicts Ile3029Val is benign to the protein structure/function. Also, no mutations in nearby codons have been reported in association with CPVT, and Ile3029Val does not occur in one of the mutation hotspot regions of the RYR2 gene (Medeiros-Domingo A et al., 2009). We cannot definitively determine if Ile3029Val is a disease-causing mutation or a rare benign variant. The variant is found in CPVT panel(s). -

The p.I3029V variant (also known as c.9085A>G), located in coding exon 64 of the RYR2 gene, results from an A to G substitution at nucleotide position 9085. The isoleucine at codon 3029 is replaced by valine, an amino acid with highly similar properties. This amino acid position is well conserved in available vertebrate species. In addition, this alteration is predicted to be tolerated by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. -
