Color Diagnostics, LLC DBA Color Health RCV001524697 SCV001734633 uncertain significance Cardiomyopathy 2021-07-15 criteria provided, single submitter clinical testing This missense variant replaces tyrosine with cysteine at codon 2874 of the RYR2 protein. Computational prediction suggests that this variant may have deleterious impact on protein structure and function (internally defined REVEL score threshold >= 0.7, 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.
Invitae RCV002568793 SCV003455268 uncertain significance Catecholaminergic polymorphic ventricular tachycardia 1 2022-03-27 criteria provided, single submitter clinical testing 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. 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 RYR2 protein function. ClinVar contains an entry for this variant (Variation ID: 1171511). This variant has not been reported in the literature in individuals affected with RYR2-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change replaces tyrosine, which is neutral and polar, with cysteine, which is neutral and slightly polar, at codon 2874 of the RYR2 protein (p.Tyr2874Cys).
