Malignant hyperthermia, susceptibility to, 1 Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | All of Us Research Program, National Institutes of Health | Oct 23, 2023 | This missense variant replaces serine with glycine at codon 3656 of the RYR1 protein. Computational prediction suggests that this variant may not impact protein structure and function (internally defined REVEL score threshold <= 0.5, PMID: 27666373). To our knowledge, functional studies have not been reported for this variant. This variant has not been reported in individuals affected with RYR1-related disorders in the literature. This variant has been identified in 1/251458 chromosomes in the general population by the Genome Aggregation Database (gnomAD). The available evidence is insufficient to determine the role of this variant in disease conclusively. Therefore, this variant is classified as a Variant of Uncertain Significance. - |
RYR1-related disorder Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Oct 31, 2016 | In summary, this variant is a rare missense change that is not predicted to affect protein function. There is no indication that it causes disease, but the available evidence is currently insufficient to prove that conclusively. Therefore, it has been classified as a Variant of Uncertain Significance. Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated, but these predictions have not been confirmed by published functional studies. This variant is present in population databases (rs774373483, ExAC 0.01%) but has not been reported in the literature in individuals with a RYR1-related disease. This sequence change replaces serine with glycine at codon 3656 of the RYR1 protein (p.Ser3656Gly). The serine residue is moderately conserved and there is a small physicochemical difference between serine and glycine. - |
