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 p.Val3711Glu variant in RYR2 has not been previously reported in individuals with cardiomyopathy or in large population studies. Computational prediction to ols and conservation analysis do not provide strong support for or against an im pact to the protein. In summary, the clinical significance of the p.Val3711Glu v ariant is uncertain. -

This sequence change replaces valine, which is neutral and non-polar, with glutamic acid, which is acidic and polar, at codon 3711 of the RYR2 protein (p.Val3711Glu). This variant is not present in population databases (gnomAD no frequency). This missense change has been observed in individual(s) with left ventricular noncompaction (PMID: 33500567). ClinVar contains an entry for this variant (Variation ID: 505023). 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. -

The p.V3711E variant (also known as c.11132T>A), located in coding exon 80 of the RYR2 gene, results from a T to A substitution at nucleotide position 11132. The valine at codon 3711 is replaced by glutamic acid, an amino acid with dissimilar properties. This alteration has been reported in a left ventricular non-compaction (LVNC) cohort; however, clinical details were limited (Mazzarotto F et al. Genet Med, 2021 05;23:856-864). 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. -
