Functional Effects of Mutations in KvLQT1 that Cause Long QT Syndrome

Mutations in KvLQT1. Introduction: The long QT syndrome (LQT) is caused by mutations in genes encoding ion channels that modulate the duration of ventricular action potentials. One of these genes, KVLQT1, encodes an α subunit that coassembles with another subunit, hminK, to form the cardiac slow delayed rectifier (IKs) K+ channel.
