| Outline of Final Research Achievements |
The purpose of this study was to identify genetic background and genotype-phenotype correlation, and then to develop personalized medicine based on genotypes and phenotypes in various arrhythmia syndromes. We found that mutations in SCN5A promoter were associated with Brugada syndrome, early repolarization syndrome, idiopathic ventricular fibrillation, sinus node dysfunction, atrioventricular block, and atrial fibrillation. With our original next generation sequencing assay, which screens about 550 genes that regulate cardiac electrophysiology, we identified multiple candidate genes in arrhythmia syndromes (Circ Arrhythmia 2014). We contributed international genome-wide association study and identified novel loci associated with Brugada syndrome (Nature Genetics 2013). The result of this study have already been clinically used for personalized medicine and life style modification in order to decrease arrhythmia events and to prevent sudden cardiac death.
