项目摘要

Alcohol Use Disorder (AUD) is substantially heritable syndrome with high public-health impact the etiology of which remains poorly understood. Over the last decade, genome-wide association studies (GWAS) have been successfully applied to an increasing number of complex biomedical and neuropsychiatric syndromes leading to important insights into biological causal pathways. Results have uniformly shown these disorders to be higher polygenic with small effect-size risk variants. However, progress in the molecular genetic dissection of AUD has been slow due to lack of adequate sample sizes of well-characterized severely ill cases. In response to this concern, NIAAA issued on 4/3/17 NOT-AA-17-002 “Submission of Applications Containing Genome- Wide Association Studies.” This proposal was designed to meet the goals laid out by NIAAA in this announcement. Because of low recruitment costs, the viability of which have been tested by pilot studies, we can, within the confines of an R0-1 budget, assess and genotype 12,000 cases of severe DSM-5 AUD. However, this application should not be viewed as only a “stand-alone” project, but as part of NIAAA’s plan to combine results across multiple studies funded under this initiative and ongoing efforts of the Psychiatric Genomics Consortium (PGC) to gain sufficient aggregate sample size for molecular analysis. Assessment of complete DSM-5 criteria for AUD, associated key co-morbidities (depression, drug abuse, antisocial personality) and other risk factors (e.g. personality) will be performed by an avatar aided tablet/web program. We will collect a severe and ethnically diverse sample from two clinical data collection networks (Hazelden- Betty Ford and Baltimore Treatment Network) and via the web from the Faces and Voices of Recovery. Scientific aims include i) identification, from public sources, of ethnically matched screened alcohol-exposed controls with GWAS, ii) complete imputation and quality control checks of genotype data, iii) performance of GWAS analyses of each super-population and a meta-analysis across ethnic samples, iv) establishment of collaborative links with the PGC and other NIAAA projects to implement cross-samples analyses, v) performance of gene and geneset analyses to seek further insights into risk pathways to AUD, vi) examination of phenotypic heterogeneity within AUD using our rich measures of symptomatology, personality, and comorbidity and attempted molecular validation of these subtypes and vii) use of polygenic risk scores (with our study serving as both a test and training sample) and genetic correlations to better understand the commonality of genetic risk between AUD and other key psychiatric and substance using disorders. With this and parallel similar projects, sufficient sample sizes of AUD cases and associated controls will be ascertained to identify risk SNPs, trace these to their relevant risk genes and use these aggregate findings to provide insight into biological etiologic pathways to AUD risk. Such pathways can then lead to new potential treatment and prevention strategies for the critical but poorly understood syndrome of AUD.

酒精使用障碍（AUD）是基本可遗传的综合症，具有很高的公共卫生影响这仍然很少理解。成功地应用于越来越多的复杂的生物肾上腺素化和神经精神综合征对生物因果途径的重要见解。较高的多基因具有较小的效应大小的风险变异。由于缺乏足够的样本量，因此AUD的响应不足。这种担忧，NIAAA在4/3/17 not-aa-17-002上进行了iSSeed。广泛的协会研究。宣布，由于招聘成本低，其生存能力已通过试点研究进行了测试在R0-1预算的范围内，可以评估和基因型12,000例严重DSM-5 AUD。但是，此应用程序不被视为“独立”项目，而是NIAA计划的一部分结合多个研究基金会基金会基金会的结果和精神病的持续努力基因组合联盟（PGC）获得足够的样本量来评估完整的DSM-5 AUD，相关关键合并症的标准（抑郁，药物ABSE，反社会个性）和其他风险因素（例如个性）将由头像辅助平板电脑/网络程序执行。我们将从两个临床数据收集网络（Hazelden- 贝蒂·福特（Betty Ford）和瓦尔蒂莫尔（Valtimore）的治疗网络）以及通过恢复的脸和声音通过网络。科学目的包括i）从公共来源识别种族匹配的筛查酒精暴露使用GWAS的控制，ii）基因型数据的计算和质量控制检查，iii） GWAS分析每个超级人群和跨种族样本的荟萃分析，iv）建立与PGC和其他的协作链接基因和基因组分析的性能进一步寻求通往AUD的风险途径，VI）检查使用我们丰富的症状，人格和D的表型异质性这些亚型和VII的合并症和尝试的分子验证验证）使用多基因风险评分（与我们的研究既可以作为测试和训练样本）和遗传相关性，以更好地了解您 AUD和其他关键的精神病和物质之间的遗传风险和平行的类似项目，AUD案例和相关控件的足够样本大小将是屈服要识别风险SNP，请追踪其相关风险基因基因Anese这些tosindings以提供洞悉此类途径的生物学病因学途径。以及对AUD的关键但贫困综合症的预防策略。
