Transcriptome-wide association study of cardiovascular outcomes in chronic kidney disease: The chronic renal insufficiency cohort.

ABSTRACT: Transcriptome-wide association studies (TWASs) are powerful for identifying gene-trait associations by integrating gene expression and genome-wide association data, but findings may be impacted by the choice of gene expression reference. We performed TWAS of cardiovascular outcomes using multi-tissue and ancestry-matched gene expression references. We used data from the Chronic Renal Insufficiency Cohort Study for participants of African (AFR, n = 1,512) and European (EUR, n = 2,067) ancestry and three outcomes: all-cause stroke, coronary heart disease, and heart failure. We performed TWASs using EUR and AFR predicted gene expression reference panels and multi-tissue TWAS by integrating gene expression from 10 GTEx selected tissues. TWAS identified KDELR2 associated with heart failure in A
