A lack of association between the CRP rs2794520 polymorphism and coronary artery disease.

Coronary artery disease (CAD) is mainly caused by atherosclerosis, which is closely associated with the C-reactive protein (CRP), a systemic inflammatory mediator. The aim of the present study was to examine whether the CRP rs2794520 polymorphism played a role in the risk of CAD. A total of 459 CAD patients and 432 non-CAD controls were recruited in the case-control study. Genotyping was performed on the SEQUENOM® Mass-ARRAY iPLEX® platform according to the manufacturer's instructions. The results showed that CRP rs2794520 was not associated with CAD. A further breakdown analysis by age or gender also indicated a lack of association between rs2794520 and CAD. In addition, the CRP rs2794520 polymorphism was not associated with the severity of CAD, which was represented by the number of coronary arteries with stenosis. In conclusion, there was no contribution of the CRP rs2794520 polymorphism to the risk of CAD.
