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]

Catecholaminergic polymorphic ventricular tachycardia Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | All of Us Research Program, National Institutes of Health | Feb 24, 2023 | This missense variant replaces histidine with arginine at codon 4396 of the RYR2 protein. Computational prediction suggests that this variant may have deleterious impact on protein structure and function (internally defined REVEL score threshold >= 0.7, PMID: 27666373). To our knowledge, functional studies have not been reported for this variant. This variant has not been reported in individuals affected with RYR2-related disorders in the literature. This variant has been identified in 1/244202 chromosomes in the general population by the Genome Aggregation Database (gnomAD). The available evidence is insufficient to determine the role of this variant in disease conclusively. Therefore, this variant is classified as a Variant of Uncertain Significance. - |
Catecholaminergic polymorphic ventricular tachycardia 1 Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Sep 02, 2016 | In summary, this variant is a novel missense change with uncertain impact on protein function. It has been classified as a Variant of Uncertain Significance. This variant occurs within one of the three regions of the RYR2 gene (N-terminal domain, central domain, or channel region) where other pathogenic variants have been reported to cluster (PMID: 19926015) Algorithms developed to predict the effect of missense changes on protein structure and function do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Benign"; Align-GVGD: "Class C25"). This variant is not present in population databases (ExAC no frequency) and has not been reported in the literature in individuals with a RYR2-related disease. This sequence change replaces histidine with arginine at codon 4396 of the RYR2 protein (p.His4396Arg). The histidine residue is highly conserved and there is a small physicochemical difference between histidine and arginine. - |
