Abstract :
Inflammatory bowel diseases (IBDs), which include ulcerative colitis (UC) and Crohn’s disease
(CD), are inflammatory disorders that affect the gastrointestinal tract. A combination of inflammatory cytokines
has an important role in IBD development. Genome-wide association studies have shown that polymorphisms in
the interleukin-23R gene (IL-23R) increase susceptibility to IBD. The aim of this study was to investigate the IL-
23R 3' UTR SNP to determine a potential association between genotype distribution and IBD.
Methods: The case group included 102 IBD patients and the control group included 107 healthy individuals.
IL-23R polymorphisms rs10889677 were genotyped using PCR-RFLP analysis. RFLP results were confirmed
by direct sequencing.
Results: The allele and genotype frequencies in patients and controls were evaluated and compared, and no
significant association between this functional rs10889677 polymorphism and risk of IBD was observed
(P=0.587; adjusted OR: 0.89; 95% CI: 0.597-1.339). We also found no significant association between CD
(14.71%) and UC (85.29%) patients in allele or genotype levels (P>0.05).
Conclusions: Our results suggest that the rs10889677 A>C polymorphism is not a potential prognostic marker
in Iranian patients with IBD
