Our previous work implied that interleukin 6 (IL6) may be a biological marker for major depressive disorder (MDD). In this study, we performed a comprehensive genetic study to determine the association between the gene encoding IL6 (IL6) and MDD in Han Chinese. There were 50 drug-naïve MDD patients and 50 healthy controls undergoing an mRNA expression study. A sample of 772 patients with MDD and 759 healthy controls were used for genetic analysis. Next, we performed an eQTL analysis to identify whether risk SNP(s) is associated withIL6expression in brain. Our results showed that patients with MDD have higher levels ofIL6than healthy controls (P= 0.008). The SNP rs1800797 has a significant association with MDD (P= 0.01) in a dominant model. The eQTL analysis showed a marginally significant association between the rs1800797 andIL6expression in the frontal cortex (P= 0.087). Our preliminary findings are suggestive of an association between rs1800797 and the risk of MDD. Further investigations are required to evaluate this association in larger samples to increase statistical power and to examine the correlation between rs1800797 andIL6methylation patterns.
