IL6 and obesity disorder: Previous studies have shown that some of the SIRT1 SNPs are associated with BMI and obesity, glucose tolerance and diabetes, blood pressure, cholesterol metabolism and coronary artery calcification, all of which contribute to the CAD phenotype.15-19 We examined the possible association between rs1467568 and rs7895833 in SIRT1 and BMI, and levels of total cholesterol, LDL, HDL, triglycerides, fasting glucose, fasting insulin, HbA1c, hsCRP, or IL-6 in CAD patients and control groups, but did not observe any association.
