Interleukin-18 Gene Polymorphisms in Tunisian Patients with Inflammatory Bowel Disease

Abstract

The two SNPs at position -607 (C/A) and -137 (G/C) in the promoter region of the IL-18 gene was associated with the development of UC but not CD, providing a strong support for an IBD susceptibility gene in the region surrounding IL-18. It remains to be determined precisely how the IL-18 alleles influence the pathogenesis of IBD.
