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]

The c.13329-11T>G variant in RYR2 has not been previously reported in individuals with cardiomyopathy, but has been identified in 5/98830 European chromosomes by gnomAD (http://gnomad.broadinstitute.org). This variant is located in the 3' splice region. Computational tools do not suggest an impact to splicing. However, this information is not predictive enough to rule out pathogenicity. In summary, the clinical significance of the c.13329-11T>G variant is uncertain. ACMG/AMP criteria applied: BP4. -
