Ulcerative colitis (UC) is a complex polygenic disease in which gene-environment interactions are important. Some studies have reported that proinflammatory polymorphisms in tumor necrosis factor-alpha-308 (TNF-alpha-308) gene promoter (substitution G-->A, designated as TNF1 and TNF2) is associated with increased UC risk. However, the results of individual studies have been inconsistent.
