Variant summary
Our verdict is Likely benign. Variant got -5 ACMG points: 3P and 8B. PM2PP2BP6_Very_Strong
The NM_000540.3(RYR1):c.10100A>G(p.Lys3367Arg) variant causes a missense change involving the alteration of a conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. Variant has been reported in ClinVar as Likely benign (★★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. K3367N) has been classified as Uncertain significance.

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]

Likely benign, reviewed by expert panel | curation | ClinGen Malignant Hyperthermia Susceptibility Variant Curation Expert Panel, ClinGen | Apr 20, 2021 | This pathogenicity assessment is relevant only for malignant hyperthermia susceptibility (MHS) inherited in an autosomal dominant pattern. Variants in RYR1 can also cause other myopathies inherited in an autosomal dominant pattern or in an autosomal recessive pattern. Some of these disorders may predispose individuals to malignant hyperthermia. RYR1 variants may also contribute to a malignant hyperthermia reaction in combination with other genetic and non-genetic factors and the clinician needs to consider such factors in making management decisions. This sequence variant predicts a substitution of lysine with arginine at codon 3367 of the RYR1 protein, p.(Lys3367Arg). This variant was not present in a large population database (gnomAD) at the time this variant was interpreted. This variant has been reported in an individual with a personal or family history of an MH episode without an in vitro contracture test (IVCT) or caffeine halothane contracture test (CHCT) result (PMID:16732084). Functional studies in HEK293 cells do not show an increased sensitivity to RYR1 agonists, BS3_Supporting (PMID:32535660). A REVEL score of 0.632 supports neither a pathogenic nor a benign status for this variant. Based on using Bayes to combine criteria this variant is assessed as Likely Benign, (PMID: 29300386).
