Two SNPs from chromosome 4q25, rs2200733 and rs10033464, were found to be associated with atrial fibrillation in a study of both European and Asian populations. The odds ratio associated with one or more copies of either risk allele was ~1.4x.[PMID 17603472]

[PMID 18931155] The results derived from a study of 78 Italians with atrial fibrillation (AF) and atrial flutter (AFL) agree with previously reported findings from the Icelandic study ([PMID 17603472]), which also found that the rs2200733(T) was associated with AF/AFL disease.

[PMID 18991354] In 1,661 Icelandic ischemic stroke samples and two large European replication sets combined, rs2200733 was associated with cardioembolic stroke (CES) (odds ratio 1.54, p = 8.05 x 10e-9). rs2200733 even showed association to ischemic stroke that was not classified as cardioembolic stroke.

[PMID 19141561OA-icon.png] rs2200733 and rs10033464 are strongly associated with AF in four cohorts of European descent.

[PMID 21414601OA-icon.png] A study of 1,166 Caucasian patients following coronary artery bypass grafting concluded that rs2200733(T) carriers had increased long-term mortality (hazard ratio 1.57, CI: 1.10 - 2.24) and higher risk for postoperative atrial fibrillation (odds ratio 1.41, CI: 1.04 - 1.91).

[PMID 24270849OA-icon.png] rs2200733 was found to be associated with atrial fibrillation based on a study by the eMERGE network in which electronic medical records were searched to find clinical associations associated with selected SNPs.
