Invitae RCV002534827 SCV000946449 uncertain significance Catecholaminergic polymorphic ventricular tachycardia 1 2022-05-03 criteria provided, single submitter clinical testing This sequence change replaces arginine, which is basic and polar, with histidine, which is basic and polar, at codon 2806 of the RYR2 protein (p.Arg2806His). The frequency data for this variant in the population databases is considered unreliable, as metrics indicate poor data quality at this position in the gnomAD database. This variant has not been reported in the literature in individuals affected with RYR2-related conditions. ClinVar contains an entry for this variant (Variation ID: 651150). 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 not expected to disrupt RYR2 protein function. 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.
Ambry Genetics RCV002442692 SCV002677773 uncertain significance Cardiovascular phenotype 2020-08-13 criteria provided, single submitter clinical testing The p.R2806H variant (also known as c.8417G>A), located in coding exon 56 of the RYR2 gene, results from a G to A substitution at nucleotide position 8417. The arginine at codon 2806 is replaced by histidine, an amino acid with highly similar properties. This amino acid position is highly conserved in available vertebrate species. In addition, this alteration is predicted to be tolerated by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear.
