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]

RYR2 NM_001035.2 exon 31 p.Gln1293Glu (c.3877C>G): This variant has not been reported in the literature but is present in 2/23972 African alleles in the Genome Aggregation Database (http://gnomad.broadinstitute.org/variant/). Evolutionary conservation and computational predictive tools for this variant are unclear. In summary, data on this variant is insufficient for disease classification. Therefore, the clinical significance of this variant is uncertain. -
