Pleiotropic Expression Quantitative Trait Loci Are Enriched in Enhancers and Transcription Factor Binding Sites and Impact More Genes

This dataset comprises two files that accompany the article (link to be added upon publication).

1. gwas2eqtl_colocalization_full.tar.gz

This file contains the complete colocalization dataset generated using the code from the following GitHub repository: gwas2eqtl. This dataset is used as input for the pleiotropic eQTL analysis available at gwas2eqtl_pleiotropy, which produces the figures in the article.

The dataset provides colocalization statistics for GWAS-eQTL pairs, including posterior probabilities and variant annotations.

2. gwas2eqtl0.1.3.tsv.gz

This file is a filtered version of the colocalization dataset, refined based on cutoffs of PP.H4.abf ≥ 0.75 and SNP.PP.H4 ≥ 0. This subset is utilized in the gwas2eqtl web application for data visualization.
