RCV001893639 | SCV002175327 | uncertain significance | RYR1-related disorder | 2022-10-23 | criteria provided, single submitter | clinical testing | This sequence change replaces threonine, which is neutral and polar, with methionine, which is neutral and non-polar, at codon 656 of the RYR1 protein (p.Thr656Met). This variant is present in population databases (rs4802472, gnomAD 0.006%). This variant has not been reported in the literature in individuals affected with RYR1-related conditions. ClinVar contains an entry for this variant (Variation ID: 1398835). 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) has been performed at Invitae for this missense variant, however the output from this modeling did not meet the statistical confidence thresholds required to predict the impact of this variant on 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. |

RCV004010816 | SCV004842023 | uncertain significance | Malignant hyperthermia, susceptibility to, 1 | 2023-12-13 | criteria provided, single submitter | clinical testing | This missense variant replaces threonine with methionine at codon 656 of the RYR1 protein. Computational prediction tool indicates that this variant may have an uncertain impact on protein structure and function. 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 2/251136 chromosomes 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. |
