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]

Has not been previously published as pathogenic or benign to our knowledge; In silico analysis supports that this missense variant has a deleterious effect on protein structure/function; Not located in one of the three hot-spot regions of the RYR2 gene, where the majority of pathogenic missense variants occur (Medeiros-Domingo et al., 2009); This variant is associated with the following publications: (PMID: 19926015) -

Cardiovascular phenotype Uncertain:1

Significance: Uncertain significance
Review Status: criteria provided, single submitter
Collection Method: clinical testing

The p.R1133H variant (also known as c.3398G>A), located in coding exon 28 of the RYR2 gene, results from a G to A substitution at nucleotide position 3398. The arginine at codon 1133 is replaced by histidine, an amino acid with highly similar properties. This alteration has been reported in a whole exome sequencing cohort (Landstrom AP et al. Circ Arrhythm Electrophysiol, 2017 Apr;10:). This amino acid position is poorly 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. -
