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	Oct 30, 2015	p.Pro4534Ser (CCC>TCC): c.13600 C>T in exon 94 of the RYR2 gene (NM_001035.2). The Pro4534Ser variant in the RYR2 gene has not been reported as a disease-causing mutation or as a benign polymorphism to our knowledge. Pro4534Ser was not observed in approximately 6000 individuals of European and African American ancestry in the NHLBI Exome Sequencing Project, indicating it is not a common benign variant in these populations. Pro4534Ser results in a non-conservative amino acid substitution of a non-polar Proline with a polar Serine at a position that is not well conserved across species, but is located in one of three mutation hot spot regions in the RYR2 gene (Medeiros- Domingo A et al., 2009). Nevertheless, in-silico analysis programs predict Pro4534Ser is benign to the protein structure/function. We cannot definitively determine if Pro4534Ser is a disease-causing mutation or a rare benign variant. The variant is found in POSTMORTEM panel(s). -

Note this variant was found in clinical genetic testing performed by one or more labs who may also submit to ClinVar. Thus any internal case data may overlap with the internal case data of other labs. The interpretation reviewed below is that of the Stanford Center for Inherited Cardiovascular Disease. p.Pro4534Ser (c.13600C>T) in the RYR2 gene (NM_001035) Given the lack of case data and lack of ancestry-matched controls, we consider this variant a variant of uncertain significance. I could find no report of the variant in association with disease. It is not listed in ClinVar (as of July 8th, 2014). Per Ng et al (2013) it is not listed in HGMD or any LSDB they checked. In silico analysis with PolyPhen-2 predicts the variant to be benign. The proline at codon 4534 is conserved across species. In total the variant has been seen in 1 of 7009 individuals from publicly available population datasets. There is no variation at codon 4534 listed in the NHLBI Exome Sequencing Project dataset, which currently includes variant calls on ~6500 Caucasian and African American individuals (as of July 8th, 2014). The variant was seen in 1 of 509 individuals in the ClinSeq project (Ng et al 2013), a sample not selected for arrhythmia or family history of sudden death (3.7% were Hispanic). Note that this dataset does not match the patient's ancestry (Hispanic). The variant is listed in dbSNP with the only submission being the ClinSeq data (rs199624074). -

This missense variant replaces proline with serine at codon 4534 of the RYR2 protein. Computational prediction suggests that this variant may not impact protein structure and function (internally defined REVEL score threshold <= 0.5, PMID: 27666373). To our knowledge, functional studies have not been reported for this variant. This variant has been reported in an individual afflicted with unspecified cardiomyopathy (PMID: 30847666). This variant has been identified in 11/237172 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. -

This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -
