Genes affected
RYR2 (HGNC:10484): (ryanodine receptor 2) This gene encodes a ryanodine receptor found in cardiac muscle sarcoplasmic reticulum. The encoded protein is one of the components of a calcium channel, composed of a tetramer of the ryanodine receptor proteins and a tetramer of FK506 binding protein 1B proteins, that supplies calcium to cardiac muscle. Mutations in this gene are associated with stress-induced polymorphic ventricular tachycardia and arrhythmogenic right ventricular dysplasia. [provided by RefSeq, Jul 2008]

Classification made for transcript
Verdict is Likely_pathogenic. Variant got 9 ACMG points.
PM1
?
In a hotspot region, there are 2 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 0 benign, 7 uncertain in NM_001035.3
PM2
?
Very rare variant in population databases, with high coverage;
PP2
?
Missense variant where missense usually causes diseases, RYR2
PP3
?
MetaRNN computational evidence supports a deleterious effect, 0.947
