Increased dietary ratios of ฯ6/ฯ3 polyunsaturated fatty acids have been implicated in the pathogenesis of Crohn's disease (CD), but epidemiologic data are limited. We investigated whether variants of genes that control polyunsaturated fatty acid metabolism (CYP4F3, FADS1, and FADS2), along with the dietary ratio of ฯ6/ฯ3, confers susceptibility to CD. Based on data from 182 children newly diagnosed with CD and 250 controls, we found that children who consumed a higher dietary ratio of ฯ6/ฯ3 were susceptible for CD if they were also carriers of specific variants of CYP4F3 and FADS2 genes. Our findings implicate diet-gene interactions in the pathogenesis of CD. Show less
