The RYR2 gene is associated with autosomal dominant catecholaminergic polymorphic ventricular tachycardia (CPVT) (MedGen UID: 351513), arrhythmogenic right ventricular cardiomyopathy (ARVC) (MedGen UID: 318748) and left ventricular noncompaction (LVNC) (PMID: 24394973).

Invitae tests that include this gene:
Pathogenic RYR2 variants are associated with 50%-60% of cases of CPVT and are a rare cause of ARVC and LVNC.
The RYR2 gene encodes ryanodine receptor 2, which is a large ion channel protein located in the cardiac sarcoplasmic reticulum. It regulates cardiac contraction and the release of intracellular calcium from the sarcoplasmic reticulum to the cytosol.
Invitae is a College of American Pathologists (CAP)-accredited and Clinical Laboratory Improvement Amendments (CLIA)-certified clinical diagnostic laboratory performing full-gene sequencing and deletion/duplication analysis using next-generation sequencing technology (NGS).
Our sequence analysis covers clinically important regions of each gene, including coding exons, +/- 10 base pairs of adjacent intronic sequence, and select noncoding variants. Our assay provides a Q30 quality-adjusted mean coverage depth of 350x (50x minimum, or supplemented with additional analysis). Variants classified as pathogenic or likely pathogenic are confirmed with orthogonal methods, except individual variants that have high quality scores and previously validated in at least ten unrelated samples.
Our analysis detects most intragenic deletions and duplications at single exon resolution. However, in rare situations, single-exon copy number events may not be analyzed due to inherent sequence properties or isolated reduction in data quality. If you are requesting the detection of a specific single-exon copy number variation, please contact Client Services before placing your order.
