Abstract
Multiple studies have shown that IL23 cytokine plays an essential role in the development of autoimmune diseases by activating IL17-producing helper T (Th17) cells. Given that the susceptibility loci in IL23R for Crohn's disease (CD) is present in Western population and not in Asian population; we screened the IL23R gene by DNA sequencing to identify susceptibility loci in a selected CD cohort and confirmed it in all our subjects (134 CD and 131 controls). A novel nonsynonymous SNP (p.Gly149Arg, c.445G>A) and 35 single nucleotide polymorphisms (SNPs) were identified. Among them, only rs11465788 was implicated in CD susceptibility (P = 4.9 x 10(-4), OR = 0.30). Genotype-phenotypic interaction analysis showed that rs11465788 is associated with nonstricturing and nonpenetrating disease behaviour in CD patients (P = 0.015). Our results provide the evidence that rs11465788 may influence the susceptibility and clinical features of CD in Chinese population.Entities:
