Notes

From SNPedia

One defective copy. This affects the formation of the heart and gives a higher risk of Atrial Fibrillation (quivering of the top part of the heart), and Cardioembolic and Ischemic strokes (blocked blood flow to the brain). Based on several quality studies, and confirmed for Europeans and Asians. It's recommended to eat a heart-healthy diet, and only drink alcohol in moderation, to lower the risk.
