This is a resubmission of the Collaborative Genetic study of Nicotine Dependence (COGEND), a new five-year Program Project Grant to detect and evaluate familial and non-familial causes of nicotine dependence. The goals of the program are the identification of biological mechanisms, genes and environmental features that determine nicotine consumption and predispose or protect individuals from the onset and persistence of the disorder. Improved understanding of these factors will suggest novel, powerful strategies for reducing or eliminating nicotine dependence and the massive health burden it places on all societies. Subjects and families will be recruited from comparable HMOs at three sites; The Henry Ford Hospital (Detroit), The University of Minnesota (Minneapolis-St. Paul) and Washington University (St. Louis). There are three interrelated studies: (1) a genetic epidemiology study of the families of nicotine dependent individuals, (2) a genetic linkage and candidate gene study of nicotine of nicotine dependence and related phenotypes and (3) a neuropharmacology study of the relationship between nicotine dependence and related phenotypes and (3) a neuropharmacology study of the relationship between nicotine metabolism and tobacco consumption and dependence. Candidate gene studies include case- control and family based designs to maximize power and minimize bias due to ethnic stratification. African-Americans will be over-sampled to provide a sufficient sample for statistical consumption, nicotine metabolism and assessment of familial and non-familial variables in multiple domains that are correlated with the disorder. Data management and administrative cores support these studies. Each project contributes thematically to the program. The family epidemiology project elucidates environmental and familial factors from which informative quantitative and qualitative phenotypes are derived. The linkage and candidates gene studies include a genome-wide survey, fine mapping and case-control and family based candidate gene studies to identify genes that determine nicotine consumption, and susceptibility or protection from nicotine dependence. Their effect on the incidence and familial distribution of nicotine dependence and tobacco consumption will be studied in the large of probands, controls and relatives metabolism providing biological insight into disorder and endophenotypes and candidate genes for the genetic study. Metabolic variables will be used as co-variables in the family, population and linkage studies. A team of investigators from three centers will work together to unravel this disorder. Our team includes epidemiologists, geneticists, statisticians, psychiatrists, psychologists, and pharmacologists. We hope to translate these basic biological and environmental studies into strategies to reduce the massive health burden of nicotine dependence.

这是尼古丁依赖的协作遗传研究（COGEND）的重新提交，这是一项新的五年计划项目资助，旨在检测和评估尼古丁依赖的家族和非家族原因。该计划的目标是确定生物机制，基因和环境特征，决定尼古丁的消费和易感性或保护个人从疾病的发作和持续。对这些因素的进一步了解将为减少或消除尼古丁依赖及其给所有社会带来的巨大健康负担提出新的、强有力的战略。将从三个研究中心的可比HMO招募受试者和家庭;亨利福特医院（底特律）、明尼苏达大学（明尼阿波利斯-圣保罗）和华盛顿大学（圣路易斯）。有三项相互关联的研究：（1）尼古丁依赖者家庭的遗传流行病学研究，（2）尼古丁依赖和相关表型的尼古丁遗传连锁和候选基因研究;（3）尼古丁依赖和相关表型之间关系的神经药理学研究;（3）尼古丁代谢与烟草消费和依赖之间关系的神经药理学研究。候选基因研究包括病例对照和基于家族的设计，以最大限度地提高功效并最大限度地减少由于种族分层引起的偏倚。将对非裔美国人进行过采样，以提供足够的样本用于统计消费、尼古丁代谢以及评估与该疾病相关的多个领域中的家族和非家族变量。数据管理和行政核心支持这些研究。每个项目都对该计划有主题贡献。家庭流行病学项目阐明了环境和家庭因素，从这些因素中获得了信息量和质量表型。连锁和候选基因研究包括全基因组调查，精细定位和病例对照以及基于家族的候选基因研究，以确定决定尼古丁摄入量的基因，以及对尼古丁依赖的易感性或保护。将在大量先证者、对照者和亲属代谢中研究它们对尼古丁依赖和烟草消费的发病率和家族分布的影响，为遗传研究提供对疾病和内表型以及候选基因的生物学见解。代谢变量将用作家族、人群和关联研究中的协变量。来自三个中心的一个调查小组将共同努力解开这种疾病。我们的团队包括流行病学家、遗传学家、统计学家、精神病学家、心理学家和药理学家。我们希望将这些基本的生物和环境研究转化为战略，以减少尼古丁依赖带来的巨大健康负担。
