The document describes 3'aQTL-atlas, an atlas of 3'UTR alternative polyadenylation quantitative trait loci (3'aQTLs) across 49 human tissues from over 800 individuals. The atlas identified approximately 1.49 million genetic variants associated with alternative polyadenylation. It provides a guide to search for and visualize 3'aQTLs by gene, variant ID, tissue, or genome position. Users can filter results, view boxplots and genome browsers, and find disease-associated 3'aQTLs. The goal is to provide a resource for exploring the effects of genetic variants on 3'UTR length and alternative polyadenylation across human tissues.

human normal tissues
A step-by-step guide

2. Data in 3′aQTL-atlas
 we analyzed 15253 RNA-seq samples across
49 human tissues isolated from 838
individuals (data from GTEx, version 8) and
identified approximately 1.49 million common
genetic variants associated with the APA.
