Causal Inference in Transcriptome-Wide Association Studies with Invalid Instruments and GWAS Summary Data
无效工具变量与 GWAS 汇总数据下的转录组关联研究因果推断
Transcriptome-wide association studies (TWAS) have recently emerged as a popular tool to discover (putative) causal genes by integrating an outcome GWAS dataset with another gene expression/transcriptome GWAS (called eQTL) dataset. In our motivating and target application, we'd like to identify causal genes for low-density lipoprotein cholesterol (LDL), which is crucial for developing new treatments for hyperlipidemia and cardiovascular diseases. The statistical principle…
