Interactive browser for TWAS results from hundreds of complex traits.

Chromatin TWAS

Data and analysis of chromatin/expression/splicing and schizophrenia (see below for TWAS methods). Includes genome-wide results from TWAS of expression/splicing in three tissues (four studies) and schizophrenia. Additionally, genome-wide results from TWAS of expression/splicing TWAS and chromatin activity measured in ~100 individuals (two studies) by ChIP-Seq.

Methods and data for performing a transcriptome-wide (or any other *ome-wide) association study. Includes a streamlined pipeline for quantifying genetic components of functional features (such as gene expression), building predictive models, predicting functional features into GWAS data, and joint/conditional analyses of associated features. Also includes a resource of trained predictive models from multiple large cohorts, tissues, and functional assays.
