GIRALDO, Alejandra M; LOANGO, Nelsy; CASTANO, Hugo  and  LANDAZURI, Patricia. Activity of cholesteryl ester transfer protein. Gene polymorphism in colombian patients with coronary artery disease. Rev. Colomb. Cardiol. [online]. 2012, vol.19, n.4, pp.172-179. ISSN 0120-5633.

Introduction: literature links the activity of cholesteryl ester transfer protein (CETP) with coronary heart disease by lowering cholesterol in high density lipoproteins. Additionally, recent studies have identified variations in the CETP gene, although the functional role of some of these variants on enzyme activity and coronary heart disease is unknown. Objective: to examine the association of polymorphisms TaqIB, MspI and RsaI in CETP gene, and the enzyme activity with coronary disease. Methods: we assessed the association between enzyme activity and polymorphisms TaqIB, MspI and RsaI in patients with coronary obstruction documented by angiography. Results: angiography allowed classification of patients into two groups: one (213 patients) with no significant coronary obstruction (CO <50%) and one (346 patients) with significant coronary obstruction (> 50% CO). Age was significantly higher in the latter group compared to the first. CETP activity was 95.8 and 94.7 pmol/μL.h for groups CO <50% and > 50% CO, respectively. Significant difference was found only between the alleles M1 and M2 in the general population. Conclusion: no association was found between the activity of CETP, TaqIB, MspI, RsaI polymorphisms and coronary obstruction. In this paper we describe for the first time CETP levels in TaqIB polymorphisms, MspI, RsaI for a group of Colombian patients. The description of the coronary event, the metabolic context of patients and the study of haplotypes must be improved in order to find relations with coronary disease.
