1. We sought to identify genetic alterations in cardiac ion channels in patients with micro-ischemic disease. Genetic analysis with Sanger technology and posterior bioinformatic assessment identified two rare variations with potential pathogenic effects (RyR2_p.M4019T and SCN5A_p.H445D) in two individuals. PMID: 28086167
2. Genetic analysis of the index case identified only one rare novel variant p.Ile11Ser (c.32T>G) in the RyR2 gene. Subsequent familial analysis identified segregation of the genetic variant with the disease. To our knowledge, there has been no previous case report of catecholaminergic polymorphic ventricular tachycardia associated to this missense variant. PMID: 27988446
3. Our findings provided evidence that Indel polymorphism rs10692285 might contribute to sudden unexplained death (SUD) susceptibility through affecting the expression of RYR2, which suggest that abnormal ion channel activity is very likely to be the underlying mechanism of SUD. PMID: 27987400
4. Five of the 19 patients (26.3%) had either a pathogenic variant or a likely pathogenic variant in MYBPC3 (n=1), MYH7 (n=1), RYR2 (n=2), or TNNT2 (n=1). All five variants were missense variants that have been reported previously in patients with channelopathies or cardiomyopathies PMID: 28202948

This RYR2 gene mutation is a novel rare genetic variant as it was not present in any of the international databases consulted. PMID: 28405885
12. Data suggest that post-translational modifications (phosphorylation, oxidation, and nitrosylation) of RyR2 (ryanodine receptor 2) occur downstream of production of amyloid beta-peptides through ADRB2 (beta2-adrenergic receptor) Ca2+ signaling cascade that activates PKA (protein kinase A).

15. These results also suggest that altered cytosolic Ca(2+) activation of RyR2 represents a common defect of RyR2 mutations associated with catecholaminergic polymorphic ventricular tachycardia and atrial fibrillation, which could potentially be suppressed by carvedilol or (R)-carvedilol.
