Outline of Final Research Achievements

Variants of genes encoding a variety of ion channels or their associated proteins, determining the heart impulse conduction, excitation and contraction, were found to cause inherited arrhythmias, such as long QT syndrome, Brugada syndrome, catecholaminergic polymorphic ventricular tachycardia, progressive cardiac conduction defect, and short QT syndrome. This line of study offered a typical example that the scientific progress in genetics prompted the discovery of new genes responsible for human diseases and elucidated their specific molecular mechanisms of pathogenicity. By employing the multilateral approaches such as conventional patch-clamp and other physiological analyses in a heterologous expression system, patients-derived iPS-cardiomyocytes, and integrated computer simulation method, we investigated the pathological mechanisms underlying these inherited arrhythmias.
