Research Abstract |
Gene analysis showed mutations were found in 27 out of 90 patients with long QT syndrome, 7 out of 58 patients with inherited bradyarrhythmia, 8 out of 90 patients with lone atrial fibrillation. We performed cellular electrophysiological study for detected mutations. Sixteen mutations were loss of function mutations and 2 mutations were gain of function mutations. Morpholino KCNH2 knockdown in zebrafish embryos displayed a AV block and WT hHERG RNA injection restored normal repolarization.
