T−455C; in Apo CIII gene (Dammerman, Sandkuijl, Halaas, Chung, & Breslow,1993; Groenendijk et al., 1999), PstI polymorphism in the Apo AI-CIII intragenic region (Vavatsi et al., 1995) and Gln360His in Apo AIV gene (Kretowski et al., 2006) have been studied for their effect on various lipid traits and contribution to CAD. The gene discussed is APOA4; the disease is coronary artery disorder.
