Invitae RCV000655532 SCV000777463 uncertain significance RYR1-Related Disorders 2018-11-27 criteria provided, single submitter clinical testing This sequence change replaces arginine with histidine at codon 3366 of the RYR1 protein (p.Arg3366His). The arginine residue is moderately conserved and there is a small physicochemical difference between arginine and histidine. This variant is present in population databases (rs137932199, ExAC 0.1%). Three missense variants, p.Ile1571Val, p.Arg3366His, and p.Tyr3933Cys, which includes this variant (p.Arg3366His), have been reported together in multiple individuals and families affected with RYR1-related disorders including malignant hyperthermia (MH) syndrome, congenital myopathy, central core disease (CCD), and multi minicore disease (MmD). In some cases, the phase of the three variants along with additional RYR1 variants was established, while in other cases it could not be determined. It is therefore unclear if one of the three variants or the additive effect of some or all of these mutations are causative for the RYR1-associated diseases in reported individuals (PMID: 25958340, 25735680, 25214167, 24950660, 25960145, 25658027, 21674524). ClinVar contains an entry for this variant (Variation ID: 132990). Algorithms developed to predict the effect of missense changes on protein structure and function do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0"). 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.
