Long QT syndrome 1

Common Name(s)

Long QT syndrome 1

Romano-Ward syndrome is the most common form of inherited long QT syndrome. Symptoms include arrhythmia, fainting, cardiac arrest, and sudden death. There are six different types of this syndrome, long QT 1 through 6. Each type is caused by a change in a different gene. The most prevalent form of long QT syndrome is long QT type 1. Long QT type 1 is caused by changes in the KCNQ1 gene. Romano-Ward syndrome is inherited in an autosomal dominant fashion.

Journal:

 

Type 1 long QT syndrome (LQT1) is a common type of cardiac channelopathy associated with loss-of-function mutations of KCNQ1. Currently there is a lack of drugs that target the defected slowly activating delayed rectifier potassium channel (IKs). With LQT1 patient-specific human induced ...
