| Research Abstract |
We identified 4q25 as an atrial fibrillation (AF) associated locus. Functional analyses revealed that this genetic region has enhancer and silencer function, which indicates that the cis-regulatory elements make genes in the neighborhood activated or silent, and finally that they confer the AF susceptibility. Next, as clinical study, we investigated whether the efficacy rate of pulmonary vein isolation (namely, catheter ablation for AF) depended on this SNP allele. The risk allele homozygotic carriers recurred more frequently than others. These findings might lead to clinical practice in the near future.
