Genome-wide association studies of cardiac electrical phenotypes.

abstract：AIMS:Atrial fibrillation (AF) is the most common cardiac arrhythmia, and early-onset lone AF has been linked to mutations in genes encoding ion channels. Mutations in the pore forming subunit KV4.3 leading to an increase in the transient outward potassium current (Ito) have previously been associated with the Brugada S...
