According to findings of the previous studies (18, 21), carotid atherosclerosis was defined as presence of any carotid plaque or any carotid stenosis ≥15% or mean IMT > 0.9 mm in this study, and we found that there were significant associations between the polymorphisms of IL1A rs1609682, PPARA rs4253655, and HABP2 rs7923349 and carotid atherosclerosis. This evidence concerns the gene HABP2 and carotid atherosclerosis.
