Description

For these reasons, this variant has been classified as Pathogenic. 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. This sequence change replaces arginine, which is basic and polar, with glutamine, which is neutral and polar, at codon 3903 of the RYR1 protein (p.Arg3903Gln). This variant is present in population databases (rs148399313, gnomAD 0.003%). This missense change has been observed in individual(s) with autosomal dominant malignant hyperthermia and central core disease (PMID: 16835904, 30236257, 30611313). This variant has been reported in individual(s) with autosomal recessive RYR1-related conditions (PMID: 35428369); however, the role of the variant in this condition is currently unclear. ClinVar contains an entry for this variant (Variation ID: 133017).
