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]

Review Status: no assertion criteria provided

Collection Method: clinical testing

Note this variant was found in clinical genetic testing performed by one or more labs who may also submit to ClinVar. Thus any internal case data may overlap with the internal case data of other labs. The interpretation reviewed below is that of the Stanford Center for Inherited Cardiovascular Disease. p.Ser1400Gly in the RYR2 gene. This variant is present in the 1000 Genomes browser with an overall allele frequency of 0.96% (http://browser.1000genomes.org/index.htm). This means that it is present in some 2% of individuals. In some ethnic subgroups the allele frequency is as high as 2-3%. This amino acid location is not conserved across paralog proteins RYR1-RYR3, suggesting that it is not important for channel function (https://cardiodb.org/Paralogue_Annotation/residue.php?gene=RYR2&position=1400). Yano et al. (2006) have reported that disease-causing variants in RYR2 cluster within 3 hotspot regions: the N-terminal domain (residues 77-433), the central domain (residues 2246-2534), and the C-terminal domain (residues 3778-4959). This variant falls outside of those 3 hotspots. No variation at nearby residues has been reported in HGMD in association with CPVT or ARVC (HGMD professional version as of January 17, 2014). ClinVar lists it as “Benign”, as submitted by Harvard’s Laboratory for Molecular Medicine. As of 2/2/2015 it has been reported in 14/1897 (0.74%) of African American individuals and 178/4126 (4.31%) of Caucasian individuals in the NHLBI Exome Sequencing Project dataset (for overall prevalence of 3.19%; http://evs.gs.washington.edu/EVS/), and two of the Caucasians with the variant were homozygous for it. The phenotype of the ESP individuals is not publicly available, however the cohorts that were merged to create this dataset were all either general population samples or samples recruited for common cardiovascular disease such as hypertension. It is listed in dbSNP (http://www.ncbi.nlm.nih.gov/projects/SNP) as rs56229512. -

Significance: Benign

Review Status: criteria provided, single submitter

Collection Method: clinical testing

This variant was observed in the ICSL laboratory as part of a predisposition screen in an ostensibly healthy population. It had not been previously curated by ICSL or reported in the Human Gene Mutation Database (HGMD: prior to June 1st, 2018), and was therefore a candidate for classification through an automated scoring system. Utilizing variant allele frequency, disease prevalence and penetrance estimates, and inheritance mode, an automated score was calculated to assess if this variant is too frequent to cause the disease. Based on the score and internal cut-off values, a variant classified as benign is not then subjected to further curation. The score for this variant resulted in a classification of benign for this disease. -

This alteration is classified as 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. -
