Labcorp Genetics (formerly Invitae), Labcorp RCV003756912 SCV004530788 uncertain significance RYR1-related disorder 2023-08-17 criteria provided, single submitter clinical testing 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. This variant disrupts the p.Met2120 amino acid residue in RYR1. Other variant(s) that disrupt this residue have been determined to be pathogenic (PMID: 30611313). This suggests that this residue is clinically significant, and that variants that disrupt this residue are likely to be disease-causing. 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. This variant has not been reported in the literature in individuals affected with RYR1-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change replaces methionine, which is neutral and non-polar, with isoleucine, which is neutral and non-polar, at codon 2120 of the RYR1 protein (p.Met2120Ile).
