项目摘要

PROJECT ABSTRACT The discovery of genetic risk factors for alcohol and tobacco use and dependence has largely focused on the contribution of individual genetic markers, such as single nucleotide polymorphisms (SNPs). While this approach has been useful in mapping the genetic liability of rare diseases with a Mendelian pattern of inheritance, the approach has had limited success with complex diseases characterized by a more polygenetic architecture. The identification of a set of genetic factors that account for individual differences in the liability to use and misuse alcohol and tobacco/nicotine will be a major step in understanding mechanisms of undercontrolled use. Moreover, the development of novel resources to predict or infer risk for problematic use of alcohol and tobacco based on genetic factors that largely explain individual differences in alcohol and tobacco use/problems, as well as other behavioral or neurocognitive phenotypes, will be a major step in translating research discoveries into prevention strategies. The current proposal addresses the problem of limited predictive power in alcohol and tobacco/nicotine genetic studies by proposing novel research that uses an integrative approach and existing data and bioinformatics resources to: (1) localize genetic variants that comprise the additive genetic effects on alcohol and tobacco use and dependence, and (2) developing a novel and freely-available resource that enhances the way existing genetically informed samples are used for alcohol and tobacco risk prediction. The current application assembles a multidisciplinary team of molecular genetics and computational and statistical geneticists to execute these project aims.

项目摘要酒精和烟草使用和依赖的遗传风险因素的发现主要集中在单个遗传标记的贡献，如单核苷酸多态性（SNP）。虽然这种方法在绘制具有孟德尔遗传模式的罕见疾病的遗传易感性方面很有用，这种方法在以多基因结构为特征的复杂疾病中取得的成功有限。的确定一组遗传因素，说明使用和滥用倾向的个体差异酒精和烟草/尼古丁将是了解控制不足的使用机制的一个重要步骤。此外，开发新的资源来预测或推断酒精和烟草使用问题的风险，遗传因素在很大程度上解释了酒精和烟草使用/问题的个体差异，作为其他行为或神经认知表型，将是将研究发现转化为预防战略。目前的提案解决了酒精预测能力有限的问题，烟草/尼古丁遗传研究，提出新的研究，使用综合方法和现有的数据和生物信息学资源，以：（1）本地化遗传变异，包括加性遗传效应酒精和烟草的使用和依赖，以及（2）开发一种新的和免费提供的资源，增强了现有基因信息样本用于酒精和烟草风险预测的方式。的目前的申请汇集了一个多学科的团队，分子遗传学和计算和统计遗传学家执行这些项目的目标。
