Variant summary: RYR2 c.7689A>G alters a conserved nucleotide resulting in a synonymous change. Several computational tools predict a significant impact on normal splicing: Two predict the variant abolishes a cryptic 3' acceptor site. Two predict the variant creates a 3' acceptor site. However, these predictions have yet to be confirmed by functional studies. The variant allele was found at a frequency of 7.2e-05 in 249284 control chromosomes, predominantly at a frequency of 0.00015 within the Non-Finnish European subpopulation in the gnomAD database. The observed variant frequency within Non-Finnish European control individuals in the gnomAD database is approximately 4 fold of the estimated maximal expected allele frequency for a pathogenic variant in RYR2 causing Catecholaminergic Polymorphic Ventricular Tachycardia phenotype (3.4e-05), strongly suggesting that the variant is a benign polymorphism found primarily in populations of Non-Finnish European origin. To our knowledge, no occurrence of c.7689A>G in individuals affected with Catecholaminergic Polymorphic Ventricular Tachycardia and no experimental evidence demonstrating its impact on protein function have been reported. Co-occurrences with other pathogenic variant(s) have been reported (MYH7 c.2717A>G, p.D906G), providing supporting evidence for a benign role. Four submitters have cited clinical-significance assessments for this variant to ClinVar after 2014. All submitters classified the variant as likely benign. Based on the evidence outlined above, the variant was classified as benign. -

RYR2-related disorder Benign:1
This variant is classified as likely benign based on ACMG/AMP sequence variant interpretation guidelines (Richards et al. 2015 PMID: 25741868, with internal and published modifications). -
Cardiovascular phenotype Benign:1
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. -
