IL-6-174G/C and IL-6-572C/G polymorphisms are associated with increased risk of coronary artery disease

Abstract

We conducted this case-control study to investigate the genetic role of IL-1β+3954C/T, IL-6-174G/C, IL-6-572C/G, IL-10-1082A/G, and IL-10-819C/T in the development of coronary artery disease (CAD) in a Chinese population. Polymorphisms IL-1β+3954C/T, IL-6-174G/C, IL-6-572C/G, IL-10-1082A/G, and IL-10-819C/T were determined by polymerase chain reaction restriction fragment length polymorphism assay. The CAD patients were more likely to be cigarette smokers, have a history of hypertension, have a higher value of total cholesterol, triglycerides, and low-density lipoprotein cholesterol, and have a lower value of high-density lipoprotein cholesterol. Conditional logistic regression analyses showed that the CC genotype of IL-6-174G/C and IL-6-572C/G gene polymorphisms are associated with an increased risk of CAD.
