ABCA1 and coronary artery disorder: Among them, G-395C, C-290T, and C-7T were reported to be negatively related to serum HDL levels, -14 > T positively correlated with HDL levels, and variations in the ABCA1 non-coding regions G-191C, C69T, C-17G, and InsG319 closely related to clinical outcomes but did not alter serum lipid levels in coronary artery disease (CAD) patients [54].
