The GTEx Consortium adopts a strategy called expression quantitative trait loci (eQTL) mapping that allows the researchers to generate a comprehensive catalogue of associations between genetic variation and gene expression across many tissues in many individuals. The processed data are available in this website (see: Nat Genet. 2013 June ; 45(6): 580–585; Ward & Gilad Nature 550:190, 2017). Registration not required.
