Abstract

Evidence from four independent linkage studies and two meta-analyses of genome-wide data support the existence of a locus conferring susceptibility to inflammatory bowel diseases (IBD) in chromosomal region 19p. Identification of a susceptibility allele in this approximately 28.5 Mb region with over 600 genes is a formidable task. To tackle this problem, we undertook two approaches: (1) haplotype-based candidate-gene screen, and (2) evaluation of previously reported associations. For the former, we selected genes with potential implication in IBD pathogenesis based on published functional and expression data, typed SNPs, constructed haplotypes, screened for association in 180 IBD trios, and followed up preliminary associations in 343 IBD patients and 207 control individuals. Overall, we analyzed 465 SNPs, and 260 haplotypes distributed across 56 candidate genes. We found suggestive evidence of association (nominal P
