ClinGen Malignant Hyperthermia Susceptibility Variant Curation Expert Panel,ClinGen RCV001588936 SCV001816163 likely pathogenic Malignant hyperthermia, susceptibility to, 1 2021-03-18 reviewed by expert panel curation 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 cysteine at codon 44 of the RYR1 protein, p.(Arg44Cys). The maximum allele frequency for this variant among the six major gnomAD populations is AMR: 0.000029, a frequency consistent with pathogenicity for MHS. This variant has been reported in two unrelated individuals who have a personal or family history of a malignant hyperthermia reaction and a positive in vitro contracture test (IVCT) or caffeine halothane contracture test (CHCT) result (when the proband was unavailable for testing a positive diagnostic test result in a mutation positive relative was counted), PS4_Moderate (PMID:12709367, PMID:24433488). Functional studies in HEK293 cells show an increased sensitivity to RYR1 agonists, PS3_Moderate (PMID:23459219). This variant resides in a region of RYR1 considered to be a hotspot for pathogenic variants that contribute to MHS, PM1 (PMID: 21118704). A REVEL score > 0.85 supports pathogenicity, PP3_Moderate. For these reasons, this variant has been classified as Likely Pathogenic. Criteria implemented: PS4_Moderate, PS3_Moderate, PM1, PP3_Moderate.

Invitae RCV001238887 SCV001411720 pathogenic RYR1-Related Disorders 2021-10-29 criteria provided, single submitter clinical testing This sequence change replaces arginine, which is basic and polar, with cysteine, which is neutral and slightly polar, at codon 44 of the RYR1 protein (p.Arg44Cys). The frequency data for this variant in the population databases is considered unreliable, as metrics indicate poor data quality at this position in the gnomAD database. This missense change has been observed in individual(s) with clinical features of autosomal dominant RYR1-related conditions (PMID: 12709367, 24433488). It has also been observed to segregate with disease in related individuals. ClinVar contains an entry for this variant (Variation ID: 133045). 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. Experimental studies have shown that this missense change affects RYR1 function (PMID: 23459219). This variant disrupts the p.Arg44 amino acid residue in RYR1. Other variant(s) that disrupt this residue have been determined to be pathogenic (PMID: 16835904, 16917943). This suggests that this residue is clinically significant, and that variants that disrupt this residue are likely to be disease-causing. For these reasons, this variant has been classified as Pathogenic.
