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]

This missense variant replaces glycine with serine at codon 3225 of 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 two individuals affected with unexplained sudden cardiac death (PMID: 29181379, 27332903). This variant has been identified in 4/249094 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. -

Has not been previously published as pathogenic or benign to our knowledge; Not observed at a significant frequency in large population cohorts (gnomAD); 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); In silico analysis supports that this missense variant has a deleterious effect on protein structure/function -

This sequence change replaces glycine, which is neutral and non-polar, with serine, which is neutral and polar, at codon 3225 of the RYR2 protein (p.Gly3225Ser). This variant is present in population databases (rs780484631, gnomAD 0.006%). This missense change has been observed in individual(s) with unexplained sudden cardiac death (PMID: 27332903). ClinVar contains an entry for this variant (Variation ID: 519478). 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) has been performed at Invitae for this missense variant, however the output from this modeling did not meet the statistical confidence thresholds required to predict the impact of this variant on RYR2 protein function. 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. -

The p.G3225S variant (also known as c.9673G>A), located in coding exon 68 of the RYR2 gene, results from a G to A substitution at nucleotide position 9673. The glycine at codon 3225 is replaced by serine, an amino acid with similar properties. This alteration was seen in one individual from a sudden cardiac death cohort, who also carried a missense alteration in MYBPC3 (Bagnall RD et al. N. Engl. J. Med., 2016 Jun;374:2441-52). This amino acid position is highly 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. -
