Catecholaminergic polymorphic ventricular tachycardia 1 Pathogenic:1Uncertain:1
This sequence change replaces glycine, which is neutral and non-polar, with arginine, which is basic and polar, at codon 3118 of the RYR2 protein (p.Gly3118Arg). 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 missense change has been observed in individual(s) with autosomal recessive ventricular fibrillation and sudden death (PMID: 33686871, 35352813). It has also been observed to segregate with disease in related individuals. ClinVar contains an entry for this variant (Variation ID: 180499). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) has been performed for this missense variant. However, the output from this modeling did not meet the statistical confidence thresholds required to predict the impact of this variant on RYR2 protein function. Experimental studies have shown that this missense change affects RYR2 function (PMID: 33686871). For these reasons, this variant has been classified as Pathogenic. -
