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]

Identified in an individual with a sudden cardiac arrest who later received a heart transplant and an individual with facioscapulohumeral muscular dystrophy and hypertrophic cardiomyopathy in the published literature; however, both individuals harbored additional cardiogenetic variants that may explain their phenotypes (Cuenca et al., 2016; Lima et al., 2017); 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: 23861362, 26899768, 28697927, 19926015, 28404607) -

The RYR2 c.2711A>G; p.Tyr904Cys variant (rs201131315) is reported in the literature in an individual affected with arrhythmogenic right ventricular cardiomyopathy (Forleo 2017). This variant was also found in an individual with hypertrophic cardiomyopathy that had other cardiac disease-related variants that may contribute to the phenotype (Lima da Silva 2018). The p.Tyr904Cys variant is reported in ClinVar (Variation ID: 179436) and is found in the general population with an overall allele frequency of 0.0146% (41/280,054 alleles) in the Genome Aggregation Database. Computational analyses predict that this variant is deleterious (REVEL: 0.956). Due to limited information, the clinical significance of this variant is uncertain at this time.

The Tyr904Cys variant in RYR2 has not been previously reported in individuals wi th cardiomyopathy but has been identified in 0.1% (2/1500) chromosomes by the Cl inSeq Project (Ng 2013 and dbSNP rs201131315). Computational analyses (amino aci d biochemical properties, conservation, SIFT, AlignGVGD, PolyPhen-2) suggest tha t the Tyr904Cys variant may impact the protein, though this information is not p redictive enough to determine pathogenicity. Additional information is needed to fully assess its clinical significance. -

Significance: Likely benign
Review Status: criteria provided, single submitter
Collection Method: clinical testing

This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -
