Potassium calcium-activated channel subfamily N member 2 (KCNN2) encodes an integral
membrane protein that forms smallconductance calcium-activated potassium (SK) channels.
Recent studies in animal models show that SK channels are important in atrial and
ventricular repolarization and arrhythmogenesis. However, the importance of SK channels in
human arrhythmia remains unclear. The purpose of the present study was to test the
association between genetic polymorphism of the SK2 channel and the occurrence of …
