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]

All of Us Research Program, National Institutes of Health

Significance:Likely pathogenic

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This missense variant replaces arginine with histidine at codon 614 of the RYR1 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 RYR1-related disorders in the literature. This variant has been identified in 7/282870 chromosomes in the general population by the Genome Aggregation Database (gnomAD). Two different missense variants occurring at the same codon, p.Arg614Cys and p.Arg614Leu, are well established as disease-causing variants (ClinVar variation ID: 12964 and 172641), indicating that arginine at this position may be important for RYR2 protein function. Based on the available evidence, this variant is classified as Likely Pathogenic. -

Significance:Likely pathogenic

Review Status:criteria provided, single submitter

Collection Method:clinical testing

ClinVar contains an entry for this variant (Variation ID: 635268). 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 RYR1 protein function. This variant disrupts the p.Arg614 amino acid residue in RYR1. Other variant(s) that disrupt this residue have been determined to be pathogenic (PMID: 1774074, 8602662, 10352931, 11493496, 11668625, 12411788). This suggests that this residue is clinically significant, and that variants that disrupt this residue are likely to be disease-causing. In summary, the currently available evidence indicates that the variant is pathogenic, but additional data are needed to prove that conclusively. Therefore, this variant has been classified as Likely Pathogenic. This variant has not been reported in the literature in individuals affected with RYR1-related conditions. This sequence change replaces arginine, which is basic and polar, with histidine, which is basic and polar, at codon 614 of the RYR1 protein (p.Arg614His). This variant is present in population databases (rs193922772, gnomAD 0.03%). -
