Expression QTL (eQTL) results were obtained from the GTEx pilot analysis v6 (22), the GEUVADIS project (23) and 12 other studies (10,24–34) in order to annotate variants with their putative regulatory target genes and the tissue(s) in which genotype has been associated with gene expression level. A wide range of QTLs, including eQTLs and other molecular QTLs such as metabolite QTLs, were also extracted from the GRASP database, build 2.0.0.0 (35,36).
