|Summary||Slightly increased risk (17.2% of white women) of Atrial Fibrillation in the 2 SNPs mentioned by 23andMe.|
The less important of the two atrial fibrillation SNPs mentioned by 23andMe has one defective copy. This slightly affects the formation of the heart and slightly increases risk of Atrial Fibrillation (quivering of the top part of the heart) that 23andMe reports. It also seems to slightly increase the risk of Cardioembolic ischemic stroke (blocked blood flow to the brain) although 23andMe doesn't mention that. For European women, 23andMe reports this as a 17.2% risk, compared to the 15.9% average. The risk is higher for men. Based on many quality studies, and confirmed for Europeans. It's recommended to eat a heart-healthy diet, and only drink alcohol in moderation, to lower the risk.
