The eQTLGen Consortium data consist of 31,684 blood and peripheral blood mononuclear cell (PBMC) samples from 37 datasets, pre-processed in a standardized way and analyzed by each cohort analyst. 25,482 (80.4%) of the samples were whole blood samples and 6,202 (19.6%) were PBMCs, and the majority of samples were of European ancestry (Supplementary Table 1). The gene expression levels of the samples were profiled by the Illumina (N=17,421; 55%), Affymetrix U219 (N=2,767; 8.7%), and Affymetrix Hu-Ex v1.0 ST (N=5,075; 16%) expression arrays and by RNA-seq (N=6,422; 20.3%). A summary of each dataset is outlined in Supplementary Table 1. Detailed cohort descriptions can be found in the Supplementary Note. All cohorts participating in this study enrolled participants with informed consent, collected and analyzed data in accordance with ethical and institutional regulations, and provided summary statistics for the meta-analyses. The information about individual institutional review board approvals is available in the original publications for each cohort (Supplementary Note) or in the cohort-specific section in Supplementary Note.
