The promoter region MIF gene focused on the -794 (CATT)5–8 microsatellite (rs5844572) and the -173 G/C (rs755622) polymorphisms have been extensively studied for its association with CAD (Lehmann et al., 2006; Tereshchenko et al., 2009; Valdes-Alvarado et al., 2014; Luo et al., 2016). The gene discussed is MIF; the disease is coronary artery disorder.
