    Description: Crohn's disease and ulcerative colitis, the two common forms of inflammatory bowel disease (IBD), affect over 2.5 million people of European ancestry, with rising prevalence in other populations. Genome-wide association studies and subsequent meta-analyses of these two diseases as separate phenotypes have implicated previously unsuspected mechanisms, such as autophagy, in their pathogenesis and showed that some IBD loci are shared with other inflammatory diseases. Here we expand on the knowledge of relevant pathways by undertaking a meta-analysis of Crohn's disease and ulcerative colitis genome-wide association scans, followed by extensive validation of significant findings, with a combined total of more than 75,000 cases and controls. We identify 71 new associations, for a total of 163 IBD loci, that meet genome-wide significance thresholds. Most loci contribute to both phenotypes, and both directional (consistently favouring one allele over the course of human history) and balancing (favouring the retention of both alleles within populations) selection effects are evident. Many IBD loci are also implicated in other immune-mediated disorders, most notably with ankylosing spondylitis and psoriasis. We also observe considerable overlap between susceptibility loci for IBD and mycobacterial infection. Gene co-expression network analysis emphasizes this relationship, with pathways shared between host responses to mycobacteria and those predisposing to IBD.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3491803/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3491803/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Jostins, Luke -- Ripke, Stephan -- Weersma, Rinse K -- Duerr, Richard H -- McGovern, Dermot P -- Hui, Ken Y -- Lee, James C -- Schumm, L Philip -- Sharma, Yashoda -- Anderson, Carl A -- Essers, Jonah -- Mitrovic, Mitja -- Ning, Kaida -- Cleynen, Isabelle -- Theatre, Emilie -- Spain, Sarah L -- Raychaudhuri, Soumya -- Goyette, Philippe -- Wei, Zhi -- Abraham, Clara -- Achkar, Jean-Paul -- Ahmad, Tariq -- Amininejad, Leila -- Ananthakrishnan, Ashwin N -- Andersen, Vibeke -- Andrews, Jane M -- Baidoo, Leonard -- Balschun, Tobias -- Bampton, Peter A -- Bitton, Alain -- Boucher, Gabrielle -- Brand, Stephan -- Buning, Carsten -- Cohain, Ariella -- Cichon, Sven -- D'Amato, Mauro -- De Jong, Dirk -- Devaney, Kathy L -- Dubinsky, Marla -- Edwards, Cathryn -- Ellinghaus, David -- Ferguson, Lynnette R -- Franchimont, Denis -- Fransen, Karin -- Gearry, Richard -- Georges, Michel -- Gieger, Christian -- Glas, Jurgen -- Haritunians, Talin -- Hart, Ailsa -- Hawkey, Chris -- Hedl, Matija -- Hu, Xinli -- Karlsen, Tom H -- Kupcinskas, Limas -- Kugathasan, Subra -- Latiano, Anna -- Laukens, Debby -- Lawrance, Ian C -- Lees, Charlie W -- Louis, Edouard -- Mahy, Gillian -- Mansfield, John -- Morgan, Angharad R -- Mowat, Craig -- Newman, William -- Palmieri, Orazio -- Ponsioen, Cyriel Y -- Potocnik, Uros -- Prescott, Natalie J -- Regueiro, Miguel -- Rotter, Jerome I -- Russell, Richard K -- Sanderson, Jeremy D -- Sans, Miquel -- Satsangi, Jack -- Schreiber, Stefan -- Simms, Lisa A -- Sventoraityte, Jurgita -- Targan, Stephan R -- Taylor, Kent D -- Tremelling, Mark -- Verspaget, Hein W -- De Vos, Martine -- Wijmenga, Cisca -- Wilson, David C -- Winkelmann, Juliane -- Xavier, Ramnik J -- Zeissig, Sebastian -- Zhang, Bin -- Zhang, Clarence K -- Zhao, Hongyu -- International IBD Genetics Consortium (IIBDGC) -- Silverberg, Mark S -- Annese, Vito -- Hakonarson, Hakon -- Brant, Steven R -- Radford-Smith, Graham -- Mathew, Christopher G -- Rioux, John D -- Schadt, Eric E -- Daly, Mark J -- Franke, Andre -- Parkes, Miles -- Vermeire, Severine -- Barrett, Jeffrey C -- Cho, Judy H -- 068545/Z/02/Wellcome Trust/United Kingdom -- 083948/Z/07/Z/Wellcome Trust/United Kingdom -- 085475/B/08/Z/Wellcome Trust/United Kingdom -- 085475/Z/08/Z/Wellcome Trust/United Kingdom -- 089120/Wellcome Trust/United Kingdom -- 090532/Wellcome Trust/United Kingdom -- 098051/Wellcome Trust/United Kingdom -- AI062773/AI/NIAID NIH HHS/ -- CA141743/CA/NCI NIH HHS/ -- CZB/4/540/Chief Scientist Office/United Kingdom -- DK043351/DK/NIDDK NIH HHS/ -- DK062413/DK/NIDDK NIH HHS/ -- DK062420/DK/NIDDK NIH HHS/ -- DK062422/DK/NIDDK NIH HHS/ -- DK062423/DK/NIDDK NIH HHS/ -- DK062429/DK/NIDDK NIH HHS/ -- DK062429-S1/DK/NIDDK NIH HHS/ -- DK062431/DK/NIDDK NIH HHS/ -- DK062432/DK/NIDDK NIH HHS/ -- DK063491/DK/NIDDK NIH HHS/ -- DK076984/DK/NIDDK NIH HHS/ -- DK084554/DK/NIDDK NIH HHS/ -- DK83756/DK/NIDDK NIH HHS/ -- ETM/137/Chief Scientist Office/United Kingdom -- ETM/75/Chief Scientist Office/United Kingdom -- G0000934/British Heart Foundation/United Kingdom -- G0600329/Medical Research Council/United Kingdom -- G0800675/Medical Research Council/United Kingdom -- G0800759/Medical Research Council/United Kingdom -- G1002033/Medical Research Council/United Kingdom -- K23 DK097142/DK/NIDDK NIH HHS/ -- M01-RR00425/RR/NCRR NIH HHS/ -- P01 DK046763/DK/NIDDK NIH HHS/ -- P01DK046763/DK/NIDDK NIH HHS/ -- P30 DK043351/DK/NIDDK NIH HHS/ -- R01 CA141743/CA/NCI NIH HHS/ -- R01 DK055731/DK/NIDDK NIH HHS/ -- T32 GM007205/GM/NIGMS NIH HHS/ -- T32GM07205/GM/NIGMS NIH HHS/ -- U01 DK062418/DK/NIDDK NIH HHS/ -- U01 DK062420/DK/NIDDK NIH HHS/ -- U01 DK062422/DK/NIDDK NIH HHS/ -- U01 DK062429/DK/NIDDK NIH HHS/ -- U01 DK062431/DK/NIDDK NIH HHS/ -- U01 DK062432/DK/NIDDK NIH HHS/ -- UL1 TR000005/TR/NCATS NIH HHS/ -- UL1 TR000124/TR/NCATS NIH HHS/ -- UL1 TR000124-01/TR/NCATS NIH HHS/ -- Medical Research Council/United Kingdom -- England -- Nature. 2012 Nov 1;491(7422):119-24. doi: 10.1038/nature11582.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Wellcome Trust Sanger Institute, Wellcome Trust Genome Campus, Hinxton, Cambridge CB10 1HH, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/23128233" target="_blank"〉PubMed〈/a〉

    Description / Table of Contents: Es wurde die Substitution von Halogenid durch Hydroxid bei einigen Halogenopentamminkobalt(III)- und -chrom(III)-Kationen in wäßrigem Dioxan bei Alkalikonzentrationen bis zu 0.1 M untersucht. Bei überschüssigem OH- (konstante Ionenstärke) wurden Geschwindigkeitskonstanten nach scheinbar erster Ordnung ermittelt. Es ist eine dem Gleichgewicht vorgelagerte Ionenpaar-Assoziation angezeigt, wobei aber nicht über die Art der Weiterreaktion des Ionenpaares - Direktaustausch oder Protonenabzug - entschieden werden kann. Bei CoIII ist die Ionenpaarbildung Stärker als bei CrIII; sie nimmt mit steigendem Dioxangehalt zu.
    Notes: The replacement, by hydroxide ion, of the coordinated halide from some halogenopentamminecobalt(III) and -Chromium(III) cations in aqueous dioxan has been studied over a range of alkali concentrations up to 0.1 M. With excess of hydroxide ion at constant ionic strength, pseudo first-order rate constants were obtained. The results support a pre-equilibrium association of complex and hydroxide ions in these media, but do not provide distinction as to whether the resulting ion-pair subsequently reacts by direct exchange or by proton removal. The extents of ion association are found to be greater for the cobalt(III) than for the chromium(III) system, increasing with the amount of dioxin in the solvent mixture.

    Description / Table of Contents: Darstellung, Säure-Hydrolyse und VIS-Spektren einiger Bromopentakis(alkylamin)-kobalt(III)-KomplexeKomplexe des Typs [Co(RNH2)5Br]2+ (R = Me, Et, n-Pr, n-Bu) wurden dargestellt. Die saure Hydrolyse wurde in wäßrigem Medium untersucht, abgesehen vom Butylaminkomplex, der auf Grund seiner geringen Löslichkeit in Wasser in Dioxan - Wasser untersucht wurde. Die saure Hydrolyse dieser Komplexe erfolgt nach pseudo-1. Ordnung und einem SN2-Mechanismus mit einem oktaedrischen Keiltyp-Übergangszustand.Die VIS-Spektren dieser Komplexe sowie des [Co(NH3)5Br]2+ wurden aufgenommen und die sich überlappenden Banden über Gauß-Kurven aufgelöst. Die Werte der Kristallfeldparameter Dq(RNH2), Dq(Br) und Dt wurden nach einer ursprünglich von Wentworth und Piper vorgeschlagenen Methode bestimmt. Die berechneten Werte stimmen gut überein mit denen anderer Autoren, und ein linearer Zusammenhang von Dq(RNH2) und ΔH° der Protonisation des RNH3+-Ions, wie er kürzlich von Mitzner u. a. beobachtet wurde, wird ebenfalls gefunden.
    Notes: Complexes of the [Co(RNH2)5Br]2+ type with R = Me, Et, n-Pr and n-Bu have been synthesized. The acid hydrolysis of these complexes have been studied in aqueous solution except for the butylamine complex, in which case the acid hydrolysis has been done in diocane-water medium because the complex is only slightly soluble in water. The acid hydrolysis of these complexes follow a pseudo-first-order reaction rate law and an SN2 mechanism with an octahedral wedge transition state has been assigned.The visible spectra of these complexes, together with [Co(NH3)5Br]2+, have been recorded and the overlapped bands have been resolved into Gaussian curves by least squares. Values of crystal field parameters Dq(RNH2), Dq(Br) and Dt in the complexes have been determined with a method originally devised by Wentworth and Piper. The calculated results agree well with those reported by other workers and a linear relationship previously observed by Mitzner et al. between Dq(RNH2) and ΔH° of proton ionization of RNH3+ ions is also found.

    Description: Crohn’s disease (CD), a form of inflammatory bowel disease, has a higher prevalence in Ashkenazi Jewish than in non-Jewish European populations. To define the role of nonsynonymous mutations, we performed exome sequencing of Ashkenazi Jewish patients with CD, followed by array-based genotyping and association analysis in 2066 CD cases and 3633 healthy controls. We detected association signals in the LRRK2 gene that conferred risk for CD (N2081D variant, P = 9.5 x 10 –10 ) or protection from CD (N551K variant, tagging R1398H-associated haplotype, P = 3.3 x 10 –8 ). These variants affected CD age of onset, disease location, LRRK2 activity, and autophagy. Bayesian network analysis of CD patient intestinal tissue further implicated LRRK2 in CD pathogenesis. Analysis of the extended LRRK2 locus in 24,570 CD cases, patients with Parkinson’s disease (PD), and healthy controls revealed extensive pleiotropy, with shared genetic effects between CD and PD in both Ashkenazi Jewish and non-Jewish cohorts. The LRRK2 N2081D CD risk allele is located in the same kinase domain as G2019S, a mutation that is the major genetic cause of familial and sporadic PD. Like the G2019S mutation, the N2081D variant was associated with increased kinase activity, whereas neither N551K nor R1398H variants on the protective haplotype altered kinase activity. We also confirmed that R1398H, but not N551K, increased guanosine triphosphate binding and hydrolyzing enzyme (GTPase) activity, thereby deactivating LRRK2. The presence of shared LRRK2 alleles in CD and PD provides refined insight into disease mechanisms and may have major implications for the treatment of these two seemingly unrelated diseases.
