Whether Crohn's disease (CD) and ulcerative colitis (UC) represent distinct disorders or comprise a continuum is a key question in inflammatory bowel disease (IBD). Recently, genome-wide association studies (GWAS) have identified several susceptibility loci, particularly for CD. This progress has enabled attempts to define the molecular similarity of IBD subtypes by specifically testing CD loci in UC. Here we extend this approach by genotyping a Swedish sample of 736 CD patients (age 49.4 ± 15.9 SD, 50.9% males), 935 UC patients (age 51.6 ± 13.1 SD, 54.2% males) and 1460 common controls (age 49.8 ± 15.6 SD, 35.6% males) for 39 of 40 loci nominally associated with CD in a recent GWAS meta-analysis.
