Cardiomyopathy Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Color Diagnostics, LLC DBA Color Health | Feb 22, 2021 | This missense variant replaces proline with glutamine at codon 990 of the RYR2 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 cardiovascular disorders in the literature. This variant has not been identified 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. - |
Catecholaminergic polymorphic ventricular tachycardia 1 Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | May 02, 2017 | In summary, this variant is a novel 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 output the following: SIFT: "Deleterious"; PolyPhen-2: "Possibly Damaging"; Align-GVGD: "Class C65". The glutamine amino acid residue is found in multiple mammalian species, suggesting that this missense change does not adversely affect protein function. These predictions have not been confirmed by published functional studies. This variant is not present in population databases (ExAC no frequency) and has not been reported in the literature in individuals with a RYR2-related disease. This sequence change replaces proline with glutamine at codon 990 of the RYR2 protein (p.Pro990Gln). The proline residue is highly conserved and there is a moderate physicochemical difference between proline and glutamine. This variant does not occur within one of the three regions of the RYR2 gene (N-terminal domain, central domain, or channel region) where other pathogenic variants have been reported to cluster (PMID: 19926015). - |
