Keyword - Long QT syndrome (KW-0454)

Definition

Protein which, if defective, causes the long QT syndrome, a heart disease which manifests itself by a prolonged QT interval on the ECG and, clinically, by a propensity for tachyarrhythmias, causing syncopes and sudden cardiac death. LQTS may be drug-induced, but mutations in genes coding for cardiac ion-channels are the cause of the hereditary forms: Romano-Ward syndrome (RWS), and Jervell and Lange-Nielsen Syndrome (JLNS).
