DESCRIPTION (provided by applicant): This proposal responds to Request for Applications RFA-MH-08-131, which seeks Collaborative R01 applications that propose to enrich pre-existing resources for schizophrenia in the NIMH Human Genetics Initiative and to apply genomic methods to further our understanding of the molecular etiology of the disorder. The overarching aims of this proposal are to quickly and cost-effectively ascertain a large sample of trio families affected by schizophrenia, and to discover causal variants for the disorder in the first family-based genome-wide association study (GWAS) of the illness. In our recently completed NIMH-funded Genetic Linkage Study of Schizophrenia (R01MH059624; PI: Ming T. Tsuang), we established a large and efficient ascertainment network and infrastructure in Taiwan, which will again be utilized and expanded in the proposed study. Through additional ascertainment within this framework, we will collect an aggregate sample of 5,000 trios with adequate power for detecting in a GWAS those variants that make even small contributions to the risk for the disorder. We will meet the overarching goals of this project by accomplishing several Specific Aims, as follows: 1) Supplement our previously collected sample of 1,200 Han Chinese schizophrenia-affected nuclear families from Taiwan by rapidly screening and collecting an additional 3,800 trios from ten ascertainment sites in Taiwan; 2) Assess the association of schizophrenia with a genome-wide panel of single-nucleotide polymorphisms and their constituent haplotypes; 3) Perform a genome-wide survey for copy-number variations related to schizophrenia; 4) Test for gene-gene interactions (epistasis); 5) Test for gene-environment interactions, such as the well-established effect of season of birth; 6) Analyze quantitative schizophrenia phenotypes, such as symptom scores and age at onset; and 7) Enhance the NIMH Genetics Initiative collections by sending all clinical data, biomaterials, and genotypes to the appropriate repositories. The project would achieve the goals of the RFA by enriching the existing resources of the NIMH Human Genetics Initiative and by applying the latest genomic research methods to further our understanding of the molecular etiology of the disorder. Also, by capitalizing on an existing clinical infrastructure and an efficient screening and assessment protocol, we will obtain a well-powered sample in a very rapid and cost-effective manner.

描述（由申请人提供）：本提案回应了申请请求RFA-MH-08-131，该申请寻求合作R 01申请，该申请旨在丰富NIMH人类遗传学倡议中精神分裂症的现有资源，并应用基因组方法来进一步了解该疾病的分子病因。该提案的总体目标是快速和具有成本效益地确定受精神分裂症影响的三个家庭的大样本，并在第一个以家庭为基础的全基因组关联研究（GWAS）中发现该疾病的因果变异。在我们最近完成的NIMH资助的精神分裂症遗传连锁研究（R 01 MH 059624; PI：Ming T. Tsuang），我们在台湾建立了一个庞大而有效的探测网络和基础设施，这将再次被利用和扩大在拟议的研究。通过在此框架内进行额外的确认，我们将收集5,000个具有足够功效的trios的汇总样本，用于在GWAS中检测那些对疾病风险贡献很小的变异。我们将透过完成以下几个特定目标来达成本计画的总体目标：1）从台湾的十个确定点快速筛选并收集额外的3，800个三人组，以补充我们先前从台湾收集的1，200个汉族精神分裂症核心家庭的样本; 2）评估精神分裂症与全基因组单核苷酸多态性及其组成单倍型的关联; 3）对与精神分裂症相关的拷贝数变异进行全基因组调查; 4）测试基因-基因相互作用（上位性）; 5）测试基因-环境相互作用，例如出生季节的明确影响; 6）分析定量精神分裂症表型，例如症状评分和发病年龄; 7）通过将所有临床数据，生物材料和基因型发送到适当的存储库来加强NIMH遗传学计划的收集。该项目将通过丰富NIMH人类遗传学倡议的现有资源，并通过应用最新的基因组研究方法来进一步了解该疾病的分子病因，从而实现RFA的目标。此外，通过利用现有的临床基础设施和有效的筛选和评估方案，我们将以非常快速和具有成本效益的方式获得具有良好功效的样本。
