In addition, even mild alterations in thyroid function are associated with weight changes, atrial fibrillation, osteoporosis, and psychiatric disorders. To identify novel variants underlying thyroid function, we performed a large meta-analysis of genome-wide association studies for serum levels of the highly heritable thyroid function markers TSH and FT4, in up to 26,420 and 17,520 euthyroid subjects, respectively. Here we report 26 independent associations, including several novel loci for TSH (PDE10A, VEGFA, IGFBP5, NFIA, SOX9, PRDM11, FGF7, INSR, ABO, MIR1179, NRG1, MBIP, ITPK1, SASH1, GLIS3) and FT4 (LHX3, FOXE1, AADAT, NETO1/FBXO15, LPCAT2/CAPNS2). Notably, only limited overlap was detected between TSH and FT4 associated signals, in spite of the feedback regulation of their circulating levels by the hypothalamic-pituitary-thyroid axis. Five of the reported loci (PDE8B, PDE10A, MAF/LOC440389, NETO1/FBXO15, and LPCAT2/CAPNS2) show strong gender-specific differences, which offer clues for the known sexual dimorphism in thyroid function and related pathologies. Importantly, the TSH-associated loci contribute not only to variation within the normal range, but also to TSH values outside the reference range, suggesting that they may be involved in thyroid dysfunction. Overall, our findings explain, respectively, 5.64% and 2.30% of total TSH and FT4 trait variance, and they improve the current knowledge of the regulation of hypothalamic-pituitary-thyroid axis function and the consequences of genetic variation for hypo- or hyperthyroidism. ; Intramural Research Program of the NIH ; NCRR ; NHLBI ; MedStar Research Institute ; NINDS ; National Center of Advancing Translational Technologies CTSI ; National Institute of Diabetes and Digestive and Kidney Diseases ; Robert Dawson Evans Endowment ; Italian Ministry of Health ; University and Research of the Autonomous Province of Bolzano ; European Union's Seventh Framework Programme ; ENGAGE project ; EPIGENESYS ; BLUEPRINT ; Dutch Innovation-Oriented Research Program on Genomics ; Netherlands Organization for Scientific Research (NWO) ; South Tyrolean Sparkasse Foundation ; Radboud University Nijmegen Medical Centre ; University of Maryland General Clinical Research Center ; Johns Hopkins University General Clinical Research Center ; Baltimore Veterans Administration Geriatric Research and Education Clinical Center (GRECC) ; Netherlands Research Institute for Diseases in the Elderly ; Erasmus Medical Center and Erasmus University, Rotterdam ; Netherlands Organization for the Health Research and Development (ZonMw) ; Dutch Ministry for Health, Welfare and Sports ; European Commission ; Municipality of Rotterdam ; German Bundesministerium fuer Forschung und Technology ; Wellcome Trust ; English Department of Health, National Institute for Health Research (NIHR) Comprehensive Biomedical Research Centre ; Canadian Institutes of Health Research, Canadian Foundation for Innovation ; Fonds de la Recherche en Santé Québec, Ministère du Développement Économique, de l'Innovation et de l'Exportation ; Lady Davis Institute of the Jewish General Hospital (JBR) ; Australian National Health and Medical Research Council ; Sir Charles Gairdner Hospital Research Fund ; Italian "Compagnia di San Paolo" ; Italian "Fondazione Cariplo" ; Leiden University Medical Centre ; Dutch Arthritis Association ; Pfizer, Groton, CT, USA ; Dutch Centre of Medical System Biology ; Netherlands Genomics Initiative (NGI), Netherlands Consortium of Healthy Aging ; Academy of Finland ; Finnish Diabetes Research Society ; Folkhälsan Research Foundation ; Novo Nordisk Foundation ; Finska Läkaresällskapet, Signe and Ane Gyllenberg Foundation ; University of Helsinki ; European Science Foundation (EUROSTRESS) ; Finnish Ministry of Education ; Ahokas Foundation ; Emil Aaltonen Foundation ; Juho Vainio Foundation ; BBSRC ; EPSRC ; ESRC ; MRC ; AXA Research Fund ; Help the Aged/Research Into Ageing (Disconnected Mind) ; Economic Structure Enhancing Fund (FES) of the Dutch government ; Dutch Ministry of Economic Affairs ; Dutch Ministry of Education, Culture and Science ; Northern Netherlands Collaboration of Provinces (SNN) ; Province of Groningen ; University of Groningen ; Dutch Kidney Foundation ; Dutch Diabetes Research Foundation ; Bristol-Myers Squibb ; Netherlands Heart Foundation ; National Computing Facilities Foundation (NCF), Netherlands ; Endocrine Research Fund

Epidemiological studies established a higher prevalence of impaired fasting glucose in men and impaired glucose tolerance in women, however, the genetic component underlying this phenomenon is not established. We assess sex-dimorphic (73,089/50,404 women and 67,506/47,806 men) and sex-combined (151,188/105,056 individuals) fasting glucose/fasting insulin genetic effects via genome-wide association study meta-analyses in individuals of European descent without diabetes. Here we report sex dimorphism in allelic effects on fasting insulin at IRS1 and ZNF12 loci, the latter showing higher RNA expression in whole blood in women compared to men. We also observe sex-homogeneous effects on fasting glucose at seven novel loci. Fasting insulin in women shows stronger genetic correlations than in men with waist-to-hip ratio and anorexia nervosa. Furthermore, waist-to-hip ratio is causally related to insulin resistance in women, but not in men. These results position dissection of metabolic and glycemic health sex dimorphism as a steppingstone for understanding differences in genetic effects between women and men in related phenotypes. ; Academy of Finland ; ADA ; Biotechnology and Biological Sciences Research Council (BBSRC) ; BHF ; Clinical Translational Science Institute ; Croatian Ministry of Science ; Directorate C - Public Health and Risk Assessment, Health & Consumer Protection ; Dutch Kidney Foundation ; Estonian Research Council ; European Research Council (ERC) ; European Regional Development Fund (ERDF) ; European Union Horizon 2020 ; Federal Ministry of Education and Research (BMBF), Germany ; Finnish Funding Agency for Technology and Innovation ; German Research Foundation ; Greek General Secretary of Research and Technology ; Icelandic National Bioethics Committee ; IFB Adiposity Diseases ; IngaBritt och Arne Lundberg's Research Foundation ; Italian Ministry of Health ; Knut & Alice Wallenberg foundation ; Kuopio University Hospital from Ministry of Health and Social Affairs ; Affymetrix, Inc ; Lundberg Foundation ; Medical Research Council (MRC) ; Mid-Atlantic Nutrition Obesity Research Center ; Ministry of Education and Culture of Finland ; MRC-GSK pilot programme ; NHLBI ; NIA ; NIH ; Nordic Centre of Excellence on Systems biology in controlled dietary interventions and cohort studies, SYSDIET ; Novo Nordisk Foundation ; NWO/ZonMW ; Spinozapremie ; Rutgers University Cell and DNA Repository ; Stockholm County Council ; Swedish Foundation for Strategic Research ; Swedish Heart-Lung Foundation ; Swedish Research Council ; Swiss National Science Foundation ; TEKES ; Torsten och Ragnar Söderbergs Stiftelser ; Wellcome Trust ; Yrjö Jahnsson Foundation ; Note that the full list of funders and grant numbers is available in the online article and in the PDF in this record
