Many SNPs in the IL‐6 gene related to CAD risk have been reported, including IL‐6‐174G/C,12IL‐6‐572C/G,13IL‐6‐597G/A,14IL‐6‐634C/G 15 and IL‐6+2954G/C 16; however, some of them were not associated with CAD risk (IL6‐597G/A and +2954G/C) or only one study reported the increased risk of CAD (IL‐6‐634C/G). Here, IL6 is linked to coronary artery disorder.
