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 E4361K variant of uncertain significance in the RYR2 gene has notbeen published as pathogenic or been reported as benign to our knowledge. However, this variant hasbeen observed in one other unrelated individual referred for ARVC genetic testing at GeneDx. This variant is not observed in large population cohorts(Lek et al., 2016; 1000 Genomes Consortium et al., 2015; Exome Variant Server). The E4361Kvariant is a non-conservative amino acid substitution, which is likely to impact secondary proteinstructure as these residues differ in polarity, charge, size and/or other properties. This substitutionoccurs at a position that is conserved in mammal. Furthermore, the E4361K variant is located in oneof the three hot-spot regions of the RYR2 gene, where the majority of pathogenic missense variantsoccur (Medeiros-Domingo et al., 2009). However, in silico analysis is inconsistent in its predictions asto whether or not the variant is damaging to the protein structure/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. 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. ClinVar contains an entry for this variant (Variation ID: 201343). This variant has not been reported in the literature in individuals affected with RYR2-related conditions. This variant is present in population databases (rs794728795, gnomAD 0.0009%). This sequence change replaces glutamic acid, which is acidic and polar, with lysine, which is basic and polar, at codon 4361 of the RYR2 protein (p.Glu4361Lys). -

The p.E4361K variant (also known as c.13081G>A), located in coding exon 90 of the RYR2 gene, results from a G to A substitution at nucleotide position 13081. The glutamic acid at codon 4361 is replaced by lysine, an amino acid with similar properties. This amino acid position is well conserved in available vertebrate species. In addition, the in silico prediction for this alteration is inconclusive. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. -
