Invitae RCV001045161 SCV001208996 uncertain significance RYR1-Related Disorders 2022-08-30 criteria provided, single submitter clinical testing This sequence change replaces glutamic acid, which is acidic and polar, with lysine, which is basic and polar, at codon 1443 of the RYR1 protein (p.Glu1443Lys). This variant is present in population databases (rs747311834, gnomAD 0.01%). 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. 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. ClinVar contains an entry for this variant (Variation ID: 842701). This variant has not been reported in the literature in individuals affected with RYR1-related conditions.
