    Principal Component analysis for CD and UC. We obtained the first ten principal components from a reference sample of 2466 self-reported Europeans downloaded from the POPRES collection using 608,435 SNPs. The inferred ancestry of the samples agreed well with country of origin of the samples and therefore we reason that sample quality control was sufficient. a. The projected PC for CD gChip samples recruited from Belgium, The Children’s Hospitcal of Phildelphia (USA), Germany, National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK, USA), and WTCCC (UK). b. The projected PC for UC gChip samples from the Children’s Hospitcal of Phildelphia (USA), Germany, Norway, Sweden, and WTCCC (UK). c. The principal component coordinates for POPRES samples from countries similar to the IBD samples. (TIFF 3988 kb

    <p>(A) <i>RNF186</i> encodes a protein with RING domain and two transmembrane domains. E3 ubiquitin-protein ligase activity is intrinsic to the RING domain. This domain contains the disease-coding variant (A64T). (B) <i>RNF186</i> expression response to <i>S. flexneri</i> in young mice (see also <a href="http://www.plosgenetics.org/article/info:doi/10.1371/journal.pgen.1003723#pgen.1003723.s011" target="_blank">Figure S11</a>). (C) Network building steps. Network is generated by mining multiple sources of interaction databases in Metacore that span human protein-protein, protein-DNA, Protein-RNA and protein-compounds interactions. (D) Transcriptional regulation model for <i>RNF186</i>. IL1-beta and TGF-beta 1 decrease <i>HNF4A</i> mRNA expression <a href="http://www.plosgenetics.org/article/info:doi/10.1371/journal.pgen.1003723#pgen.1003723-Caja1" target="_blank">[39]</a>–<a href="http://www.plosgenetics.org/article/info:doi/10.1371/journal.pgen.1003723#pgen.1003723-Wang1" target="_blank">[41]</a>. Knockdown of retinoid X receptor, alpha (<i>RXRA</i>) down-regulates <i>HNF4A</i> gene expression; RXRA interacts with <i>HNF4A</i> gene <a href="http://www.plosgenetics.org/article/info:doi/10.1371/journal.pgen.1003723#pgen.1003723-Tomaru1" target="_blank">[24]</a>. <i>HNF4A</i> is a direct target gene of caudal type homeobox 2 (CDX2); CDX2 increases <i>HNF4A</i> mRNA expression in intestinal epithelial cells <a href="http://www.plosgenetics.org/article/info:doi/10.1371/journal.pgen.1003723#pgen.1003723-Boyd2" target="_blank">[42]</a>, <a href="http://www.plosgenetics.org/article/info:doi/10.1371/journal.pgen.1003723#pgen.1003723-McKinneyFreeman1" target="_blank">[43]</a>. HNF4A binds promoter region of <i>HNF1A</i> and up-regulates its expression. HNF1A interacts with <i>RNF186</i> and regulates its transcription.</p
