Genes affected

RYR1 (HGNC:10483): (ryanodine receptor 1) This gene encodes a ryanodine receptor found in skeletal muscle. The encoded protein functions as a calcium release channel in the sarcoplasmic reticulum but also serves to connect the sarcoplasmic reticulum and transverse tubule. Mutations in this gene are associated with malignant hyperthermia susceptibility, central core disease, and minicore myopathy with external ophthalmoplegia. Alternatively spliced transcripts encoding different isoforms have been described. [provided by RefSeq, Jul 2008]

This sequence change is predicted to replace valine with methionine at codon 3088 of the RYR1 protein, p.(Val3088Met). The valine residue is highly conserved (100 vertebrates, UCSC), and is not present in a known functional domain. There is a small physicochemical difference between valine and methionine. The variant is present in a large population cohort at a frequency of 0.05% (rs145044872, 152/282,802 alleles, 1 homozygote in gnomAD v2.1.1). It has been identified in the homozygous state in a control age 70-75 (gnomAD v2.1.1), a patient with recessive congenital core myopathy (PMID: 26994242), and a case with multiple anatomical abnormalities (Mygene2.org), and compound heterozygous with a RYR1 VUS (p.Val4547Met) in a malformed foetus with pulmonary hypoplasia (CGC genetics, Portugal). Additionally, it has been identified heterozygous in a case with exertional heat stroke and a positive in vitro muscle contracture test (PMID: 26994242), a case with exercise induced rhabdomyolysis (UCL Institute of Neurology, London), and as an incidental finding in an individual with advanced terminal cancer (PMID: 28003660). The variant is not present on the European Malignant Hyperthermia Group database and has previously been reported as likely benign (ClinVar ID: 201158). Multiple lines of computational evidence predict a deleterious effect for the missense substitution (6/7 algorithms). Based on the classification scheme RMH ACMG Guidelines v1.1.1, this variant is classified as a VARIANT of UNCERTAIN SIGNIFICANCE. Following criteria are met: PP3. -

Review Status:no assertion criteria provided

Collection Method:clinical testing

The RYR1 c.9262G>A variant is predicted to result in the amino acid substitution p.Val3088Met. This variant was reported in a patient with exertional heat stroke who was also positive for an in vitro muscle contraction test. In addition, it was mentioned in the same report that the p.Val3088Met variant was previously identified in the same laboratory in the homozygous state in a patient with recessive congenital core myopathy (Roux-Buisson et al. 2016. PubMed ID: 26994242). We have detected this variant at PreventionGenetics previously in one Malignant Hyperthermia (MH) patient. This variant is reported in 0.20% of alleles in individuals of Ashkenazi Jewish descent in gnomAD. At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -

Collection Method:clinical testing

This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). No publications were found based on this search. Allele frequency data from public databases did not allow this variant to be ruled in or out of causing disease. Therefore, this variant is classified as a variant of unknown significance. -
