Summary
Exome-wide gene-burden association studies are widely used to assess gene – trait relationships. By focusing on coding variants, such analyses can directly quantify the magnitude and direction of a gene’s effect on a given trait across the proteome, information that cannot be easily derived from genome-wide associate studies. However, the lack of a standardized workflow poses a significant challenge for reproducibility. Here, we provide a customizable workflow implemented in Python 3 and Nextflow for performing exome-wide rare variant gene – trait association testing. We demonstrated its utility by replicating three recent studies. This workflow will also serve as a framework for performing similar analyses in a standardized and systematic manner.
