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 F4306S variantin the RYR2 gene has been identified in one individual with arrhythmogenic right ventricular cardiomyopathy (ARVC) (Akdis et al., 2016), and it has been identified in conjunction with additional cardiogenetic variants in one other individual referred for cardiomyopathy genetic testing at GeneDx. However, thus far, segregation data is limited or absent for this individual. The F4306S variant is observed in 7/111,248 (0.006%) alleles from individuals of European (non-Finnish) ancestry in large population cohorts (Lek et al., 2016). The F4306S variant is a non-conservative amino acid substitution, which is likely to impact secondary protein structure as these residues differ in polarity, charge, size and/or other properties. Moreover, In-silico analyses, including protein predictors and evolutionary conservation, support a deleterious effect. -

This sequence change replaces phenylalanine, which is neutral and non-polar, with serine, which is neutral and polar, at codon 4306 of the RYR2 protein (p.Phe4306Ser). This variant is present in population databases (rs776091285, gnomAD 0.006%). This missense change has been observed in individual(s) with arrhythmogenic ventricular dysplasia/cardiomyopathy (PMID: 26569459). ClinVar contains an entry for this variant (Variation ID: 201186). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae 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. -

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. -
