Polymorphisms of the cytokine genes TGFB1 and IL10 in a mixed-race population with Crohn's disease.

Background: Most Crohn's disease (CD) genes discovered in recent years are associated with biological systems critical to the development of this disease. TGFB1 and IL10 are cytokines with important roles in CD. The aim of this study was to evaluate the association between CD, its clinical features and TGFB1 and IL10 gene polymorphisms.
