Tsai et al. here utilize a multi-stage genome-wide association study in Taiwanese population to show a copy number variation in the intron of potassium interacting channel 1 gene (KCNIP1) to be strongly associated with atrial fibrillation. The study also examines the functionality of KCNIP1 in heart electrophysiological function using cultured myocytes and zebrafish.
