Brugada syndrome (BrS) is a condition characterized by a distinct ST-segment elevation in the right precordial leads of the electrocardiogram and, clinically, by an increased risk of cardiac arrhythmia and sudden death. The condition predominantly exhibits an autosomal dominant pattern of inheritanc

The long QT syndrome (LQTS) is a cardiac disorder characterized by prolongation of the QT interval on electrocardiograms (ECGs), syncope and sudden death caused by a specific ventricular tachyarrhythmia known as torsade de pointes. LQTS is caused by mutations in ion channel genes including the cardi
The long QT syndrome (LQT) is an inherited cardiac disorder that can cause sudden cardiac death among apparently healthy young individuals due to malignant ventricular arrhythmias. LQT was found to be caused by mutations in four genes LQT1, LQT2, LQT3 and LQT5, and linkage was reported for an additi
## Abstract A large Australian family affected with long QT syndrome (LQTS) was studied. The medical characteristics of the 16 clinically affected members were consistent with LQT1. A previously identified mutation in __KCNQ1__ was found in 12 affected individuals and 1 unaffected infant but absent
