Variant summary
Our verdict is Likely pathogenic. Variant got 7 ACMG points: 7P and 0B. PM1PM2PP2PP3_Moderate
The NM_001035.3(RYR2):c.6934A>G(p.Ser2312Gly) variant causes a missense change involving the alteration of a conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Synonymous variant affecting the same amino acid position (i.e. S2312S) has been classified as Likely benign.

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]

Catecholaminergic polymorphic ventricular tachycardia 1 Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Sep 26, 2016 | This sequence change replaces serine with glycine at codon 2312 of the RYR2 protein (p.Ser2312Gly). The serine residue is highly conserved and there is a small physicochemical difference between serine and glycine. This variant is not present in population databases (ExAC no frequency) and has not been reported in the literature in individuals with a RYR2-related disease. Algorithms developed to predict the effect of missense changes on protein structure and function do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Benign"; Align-GVGD: "Class C55"). In summary, this variant is a novel missense change with uncertain impact on protein function. It has been classified as a Variant of Uncertain Significance. This variant does not occur within one of the three regions of the RYR2 gene (N-terminal domain, central domain, or channel region) where other pathogenic variants have been reported to cluster (PMID: 19926015). - |
