Invitae RCV001048927 SCV001212957 uncertain significance RYR1-related disorder 2022-03-29 criteria provided, single submitter clinical testing This sequence change replaces proline, which is neutral and non-polar, with leucine, which is neutral and non-polar, at codon 966 of the RYR1 protein (p.Pro966Leu). This variant is present in population databases (rs143179371, gnomAD 0.009%). This missense change has been observed in individual(s) with autosomal recessive myopathy and/or clinical features of RYR1-related conditions (PMID: 28357410, 31127727, 32528171). ClinVar contains an entry for this variant (Variation ID: 845794). 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. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance.

All of Us Research Program, National Institutes of Health RCV004004791 SCV004825350 uncertain significance Malignant hyperthermia, susceptibility to, 1 2023-11-20 criteria provided, single submitter clinical testing This missense variant replaces proline with leucine at codon 966 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 autosomal dominant malignant hyperthermia susceptibility, although it has been reported in individuals affected with myopathy (PMID: 28357410, 31127727). This variant has not been identified 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.
