A study among patients with type 2 diabetes by Lacquemant and colleagues on the rs2241766 polymorphism of the AdipoQ gene reported that this polymorphism is associated with increased risk of coronary artery disease in diabetic patients [34] but Bacci and team found that the rs1501299 polymorphism of this same gene is associated decreased coronary artery disease risk [27] – thus creating inconsistency as to the exact role of the AdipoQ in CHD. Here, ADIPOQ is linked to type 2 diabetes mellitus.
