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 p.Arg3510Cys variant in RYR2 has been identified by our laboratory in 1 indi vidual with ARVC, but has also been identified in 0.01% (17/126310) of European chromosomes by the Genome Aggregation Database (gnomAD, http://gnomad.broadinsti tute.org; dbSNP rs201749277). Computational prediction tools and conservation an alysis suggest that the p.Arg3510Cys variant may impact the protein, though this information is not predictive enough to determine pathogenicity. In summary, th e clinical significance of the p.Arg3510Cys variant is uncertain. ACMG/AMP Crite ria applied: PP3. -

This variant is located in the RYR2 protein. Computational prediction is inconclusive regarding the impact of this variant on protein structure and function (internally defined REVEL score threshold 0.5 < inconclusive < 0.7, PMID: 27666373). To our knowledge, functional studies have not been reported for this variant. This variant has been reported in an individual affected with hypertrophic cardiomyopathy (PMID: 28771489). This variant has been identified in 20/279572 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. -

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This sequence change replaces arginine, which is basic and polar, with cysteine, which is neutral and slightly polar, at codon 3510 of the RYR2 protein (p.Arg3510Cys). This variant is present in population databases (rs201749277, gnomAD 0.01%). This variant has not been reported in the literature in individuals affected with RYR2-related conditions. ClinVar contains an entry for this variant (Variation ID: 179247). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) indicates that this missense variant is not expected to disrupt RYR2 protein function with a negative predictive value of 95%. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The p.R3510C variant (also known as c.10528C>T), located in coding exon 73 of the RYR2 gene, results from a C to T substitution at nucleotide position 10528. The arginine at codon 3510 is replaced by cysteine, an amino acid with highly dissimilar properties. This alteration has been detected in a hypertrophic cardiomyopathy cohort, but clinical details were limited (Mademont-Soler I et al. PLoS ONE. 2017;12:e0181465). This amino acid position is well conserved in available vertebrate species. In addition, this alteration is predicted to be deleterious by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. -
