Human hereditary long QT syndrome is a cardiac disease characterized by prolongation of the QT interval and increased susceptibility to ventricular arrhythmias and sudden cardiac death. Mutations in the human-ether-a-go-go-related gene (hERG), encoding the protein underlying the repolarizing cardiac I(Kr) potassium current, cause chromosome 7-linked long QT syndrome 2. Loss of function of mutant hERG channels may be caused by several mechanisms, including altered current kinetics, altered ion selectivity, or defective intracellular protein trafficking. Especially the latter category has become a focus of particular interest recently, because some of the mutant subunits display wild type current properties when normal trafficking is restored and channels are inserted in the cell membrane in vitro. This review summarizes the current knowledge on hERG channel trafficking under physiological and pathological conditions. In addition, therapeutic approaches to restore normal hERG trafficking in vitro and in vivo are discussed.
