Congenital long QT syndrome is electrocardiographically characterized by a prolonged QT interval and polymorphic ventricular arrhythmias (torsade de pointes). These cardiac arrhythmias may result in recurrent syncope, seizure, or sudden death ({7:Jongbloed et al., 1999}).

Mechanistic basis for type 2 long QT syndrome caused by KCNH2 mutations that disrupt conserved arginine residues in the voltage sensor.
 

Author(s): Christie M McBride, Ashley M Smith, Jennifer L Smith, Allison R Reloj, Ellyn J Velasco, Jonathan Powell, Claude S Elayi, Daniel C Bartos, Don E Burgess, Brian P Delisle

Journal: J. Membr. Biol.. 2013 May;246(5):355-64.

 

KCNH2 encodes the Kv11.1 channel, which conducts the rapidly activating delayed rectifier K+ current (I Kr) in the heart. KCNH2 mutations cause type 2 long QT syndrome (LQT2), which increases the risk for life-threatening ventricular arrhythmias. LQT2 mutations are predicted to prolong ...
