Interleukin-12B gene rs6887695 and rs2288831 polymorphisms are associated with an increased risk of ulcerative colitis development in Chinese Han population: A case-control study.

ABSTRACT:

Background

The association of the interleukin (IL)-12B gene rs6887695 and rs2288831 polymorphisms with ulcerative colitis (UC) risk has been extensively investigated, but results are conflicting. In this study, we investigated potential link between the IL-12B gene rs6887695 and rs2288831 polymorphisms and UC development in Chinese Han population.

Material and methods

Genotyping was performed in 367 patients and 456 controls through polymerase chain reaction-restriction fragment length polymorphism analysis. Plasma levels of IL-12B were tested using an enzyme-linked immunosorbent assay.

Results

We found that the IL-12B gene rs6887695 and rs2288831 polymorphisms were related to a significantly increased risk of UC. Subgroup analyses revealed significant associations of the IL-12B gene rs6887695 and rs2288831 polymorphisms with UC risk among females, consumers of alcohol, and those aged <40 years. Additionally, the rs6887695 and rs2288831 polymorphisms were associated with lesion location and UC treatment. Last, we found that these two polymorphisms were associated with IL-12B levels.

Conclusions

The IL-12B gene rs6887695 and rs2288831 polymorphisms were associated with a higher risk, and the clinical characteristics, of UC.
