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]

Variant classified as Uncertain Significance - Favor Benign. The 463+6C>T varian t in RYR2 has not been reported in the literature nor previously identified by o ur laboratory. This variant is located in the 5' splice region. Computational to ols do not suggest an impact to splicing, although this information is not predi ctive enough to rule out pathogenicity. Additional information is needed to full y assess the clinical significance of this variant. -
