Abstract

Some genetic loci may affect susceptibility to multiple immune system-related diseases. In the current study, we investigated whether the known susceptibility loci for celiac disease (CelD) also associate with Crohn's disease (CD) and/or ulcerative colitis (UC), the two main forms of inflammatory bowel disease (IBD), in Finnish patients. A total of 45 genetic markers were genotyped in a Finnish data set comprising 699 IBD patients and 2482 controls. Single-marker association with IBD and its subphenotypes was tested. A meta-analysis with a Swedish UC data set was also performed. A total of 12 single-nucleotide polymorphisms associated with CD and/or UC (P<0.05). In the subphenotype analysis, rs6974491-ELMO1 (P=0.0002, odds ratio (OR): 2.20) and rs2298428-UBE2L3 (P=5.44×10^-5, OR: 2.59) associated with pediatric UC and CD, respectively. In the meta-analysis, rs4819388-ICOSLG (P=0.00042, OR: 0.79) associated with UC. In the subphenotype meta-analysis, rs1738074-TAGAP (P=7.40×10^-5, OR: 0.61), rs6974491-ELMO1 (P=0.00052, OR: 1.73) and rs4819388-ICOSLG (P=0.00019, OR: 0.75) associated with familial UC, pediatric UC and sporadic UC, respectively. Multiple CelD risk loci also confer susceptibility for CD and/or UC in the Finnish and Swedish populations. Certain genetic risk variants may furthermore predispose an individual for developing a particular disease phenotype.
