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. ClinVar contains an entry for this variant (Variation ID: 1180698). This missense change has been observed in individual(s) with autosomal dominant RYR1-related myopathy (PMID: 22473935). In at least one individual the variant was observed to be de novo. This variant is not present in population databases (gnomAD no frequency). This sequence change replaces histidine, which is basic and polar, with tyrosine, which is neutral and polar, at codon 4813 of the RYR1 protein (p.His4813Tyr).
