× 10−19, and 0.003, respectively) relative to the density of these features within a 2.5-kb window of the tested eQTLs (fig. S29 and table S11). This enrichment was even more pronounced in a subset of 91 unambiguous intergenic eQTL SNPs (fig. S29). In contrast, we found sQTLs to be enriched within annotated splice junctions relative to other functional regions (Fig. 5C).
