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]

Uncertain significance, criteria provided, single submitter	clinical testing	GeneDx	May 29, 2024	Reported in one individual from a cohort of individuals not selected for cardiomyopathy, arrhythmia or family history of sudden cardiac death who underwent exome sequencing; however, a follow-up cardiac evaluation was not described (PMID: 23861362); Variant observed in unrelated individuals referred for cardiac genetic testing at GeneDx who had different genetic etiologies for their phenotypes; In silico analysis supports that this missense variant has a deleterious effect on protein structure/function; This variant is associated with the following publications: (PMID: 19926015, 23861362) -
Uncertain significance, criteria provided, single submitter	clinical testing	ARUP Laboratories, Molecular Genetics and Genomics, ARUP Laboratories	Nov 16, 2019	The RYR2 c.10680T>A; p.His3560Gln variant (rs727503404), to our knowledge, is not reported in the medical literature or gene specific databases. This variant is found in the general population with an overall allele frequency of 0.006 % (16/ 279,974 alleles) in the Genome Aggregation Database. The histidine at codon 3560 is highly conserved, but computational analyses (SIFT: tolerated PolyPhen-2: probably damaging) predict conflicting effects of this variant on protein structure / function. Due to limited information, the clinical significance of the p.His3560Gln variant is uncertain at this time. -

Uncertain:2

Uncertain significance, criteria provided, single submitter	clinical testing	Laboratory for Molecular Medicine, Mass General Brigham Personalized Medicine	Mar 12, 2014	The His3560Gln variant in RYR2 has been identified by our laboratory in 1 infant with DCM. It has also been detected in 1/948 chromosomes in a cohort that was not selected for cardiomyopathy by the ClinSeq study (Ng 2013). The affected ami no acid is conserved in evolution, suggesting that a change would not be tolerat ed. Other computational analyses do not provide strong support for or against a n impact to the protein. Additional information is needed to fully assess the cl inical significance of this variant. -
Uncertain significance, criteria provided, single submitter	clinical testing	Women's Health and Genetics/Laboratory Corporation of America, LabCorp	Mar 21, 2023	Variant summary: RYR2 c.10680T>A (p.His3560Gln) results in a non-conservative amino acid change in the encoded protein sequence. Four of five in-silico tools predict a damaging effect of the variant on protein function. The variant allele was found at a frequency of 5.7e-05 in 279974 control chromosomes (gnomAD), predominantly at a frequency of 0.00011 within the Non-Finnish European subpopulation in the gnomAD database. The observed variant frequency within Non-Finnish European control individuals in the gnomAD database is approximately 3 fold of the estimated maximal expected allele frequency for a pathogenic variant in RYR2 causing Catecholaminergic Polymorphic Ventricular Tachycardia phenotype (3.4e-05), strongly suggesting that the variant is a benign polymorphism found primarily in populations of Non-Finnish European origin. c.10680T>A has been reported in the literature in a study cohort of RYR2 positive individuals without a specific reported phenotype (Giudicessi_2019). This report does not provide unequivocal conclusions about association of the variant with Catecholaminergic Polymorphic Ventricular Tachycardia. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. Eight ClinVar submitters have assessed the variant since 2014: all classified the variant as uncertain significance. Based on the evidence outlined above, the variant was classified as VUS-possibly benign. -

Uncertain:2

Uncertain significance, criteria provided, single submitter	clinical testing	Color Diagnostics, LLC DBA Color Health	Mar 29, 2023	This missense variant replaces histidine with glutamine at codon 3560 of the RYR2 protein. Computational prediction suggests that this variant may have deleterious impact on protein structure and function (internally defined REVEL score threshold >= 0.7, PMID: 27666373). To our knowledge, functional studies have not been reported for this variant. This variant has not been reported in individuals affected with cardiovascular disorders in the literature. This variant has been identified in 16/279974 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. -

Uncertain significance, criteria provided, single submitter	clinical testing	Labcorp Genetics (formerly Invitae), Labcorp	Sep 20, 2022	This sequence change replaces histidine, which is basic and polar, with glutamine, which is neutral and polar, at codon 3560 of the RYR2 protein (p.His3560Gln). This variant is present in population databases (rs727503404, gnomAD 0.01%). This variant has not been reported in the literature in individuals affected with RYR2-related conditions. ClinVar contains an entry for this variant (Variation ID: 165117). 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 expected to disrupt 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. -

This missense variant replaces histidine with glutamine at codon 3560 of the RYR2 protein. Computational prediction tools and conservation analyses suggest that this variant may have deleterious impact on the protein function. Computational splicing tools suggest that this variant may not impact RNA splicing. To our knowledge, functional assays have not been performed for this variant nor has this variant been reported in individuals affected with cardiovascular disorders in the literature. This variant has been identified in 16/279974 chromosomes in the general population by the Genome Aggregation Database (gnomAD). 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. -

The c.10680T>A (p.H3560Q) alteration is located in exon 74 (coding exon 74) of the RYR2 gene. This alteration results from a T to A substitution at nucleotide position 10680, causing the histidine (H) at amino acid position 3560 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
