We studied markers in the genes for NRAMP1 and two mutations in the interferon-gamma receptor in relation to inflammatory bowel disease (IBD) in the following groups: 270 healthy individuals, 74 patients with Crohn's disease, 72 patients with ulcerative colitis, and 40 patients with primary sclerosing cholangitis.
The -237C-->T promoter polymorphism of the SLC11A1 gene is associated with a protective effect in relation to inflammatory bowel disease in the South African population.
five hundred and seven Crohn's disease (CD) patients, 474 ulcerative colitis (UC) patients, and 569 healthy controls were genotyped for SLC11A1 1730G>A and SLC11A1 469+14G>C using pre-designed TaqMan SNP assays.
