项目摘要
PROJECT SUMMARY
Schizophrenia is a heritable psychiatric disease affecting approximately 1% of the population. The
disease is associated with high morbidity and mortality and is a leading cause of disability. Genomewide
association studies (GWAS) have identified >100 genetic loci associated with schizophrenia. However
standard GWAS are largely limited to detecting simple point mutations, or single nucleotide polymorphisms
(SNPs), consisting of single base pair substitutions. Thus, GWAS is unable to capture complex variants such
as copy number variants (CNVs) and tandem repeats (TRs) that are not well tagged by SNPs.
Multiple lines of evidence support the hypothesis that TRs play a role in psychiatric disease. TRs are
one of the largest sources of genetic variation, are weakly tagged by SNPs, and play a significant role in
regulating gene expression and splicing. Intriguingly, >30 Mendelian disorders are caused by TR expansions.
Nearly all repeat disorders involve neurological phenotypes, many have psychiatric components, and some
implicated genes have also been identified in schizophrenia GWAS.
I hypothesize that tandem repeats play a significant role in schizophrenia risk and drive a subset of
GWAS signals. I propose to develop an array of computational techniques to integrate TRs into psychiatric and
other GWAS. In Aim 1 we will develop algorithms to accurately genotype long TR polymorphisms in large
nextgeneration sequencing cohorts. In Aim 2 we will generate a high quality reference haplotype panel for a
targeted set of TRs using traditional familybased phasing methods combined with long range phasing from
novel singlemolecule sequencing technologies. In Aim 3 we will deeply characterize medically relevant TRs in
psychiatric disease by imputing TRs into large existing GWAS cohorts. Finally, in Aim 4 we will develop a novel
haplotype test capturing genomewide TR associations from existing GWAS datasets. Taken together, these
innovations will provide a powerful framework for interrogating the role of TRs in human disease.
Genomewide scans for association (Aim 4) can be combined with targeted methods of Aims 13 for
genotyping or imputing TRs, fine mapping against other variant types, and performing functional follow up.
Technologies for high throughput TR genotyping and imputation will revolutionize our ability to discover
diseaseassociated TRs and enable unprecedented study of TRs in broad applications including GWAS,
Mendelian genetics, and cancer.
项目概要
精神分裂症是一种遗传性精神疾病,影响约 1% 的人口。
该疾病与高发病率和死亡率相关,是全基因组残疾的主要原因。
然而,关联研究 (GWAS) 已发现超过 100 个与精神分裂症相关的基因位点。
标准 GWAS 在很大程度上仅限于检测简单的点突变或单核苷酸多态性
(SNP),由单碱基对取代组成。因此,GWAS 无法捕获此类复杂的变异。
例如,未被 SNP 很好标记的拷贝数变异 (CNV) 和串联重复序列 (TR)。
多项证据支持 TR 在精神疾病中发挥作用的假设。
遗传变异的最大来源之一,被 SNP 弱标记,并在
有趣的是,超过 30 种孟德尔疾病是由 TR 扩展引起的。
几乎所有的重复性疾病都涉及神经表型,许多有精神成分,还有一些
精神分裂症 GWAS 中也发现了相关基因。

在目标 1 中,我们将开发算法来准确地对大样本中的长 TR 多态性进行基因分型。
在目标 2 中,我们将为下一代测序队列生成高质量的参考单倍型面板。
使用传统的基于家庭的分阶段方法与远程分阶段相结合的目标 TR 集
在目标 3 中,我们将深入描述医学相关 TR 的特征。
最后,在目标 4 中,我们将开发一种新颖的方法,将 TR 归入现有的大型 GWAS 队列中。
单倍型测试从现有 GWAS 数据集中捕获全基因组 TR 关联。
创新将为探究 TR 在人类疾病中的作用提供强大的框架。
全基因组关联扫描(目标 4)可以与目标 13 的靶向方法相结合
基因分型或估算 TR,针对其他变异类型进行精细映射,并执行功能跟进。
高通量 TR 基因分型和插补技术将彻底改变我们发现的能力
疾病相关的 TR 并使 TR 能够在广泛的应用中进行前所未有的研究,包括 GWAS、
孟德尔遗传学和癌症。
