Properties of local eQTLs and isoQTLs. (A) Frequency (y-axis) of the location of leading SNPs for local eQTLs and isoQTLs (permutation FDR < 0.05) with respect to meta gene structure (x-axis). Genes are normalized to five exonic regions (E1–E4 indicate exons 1 through 4; E* indicates exon 5 to the last exon) and four intronic regions (introns 1, 2, 3, and from intron 4 to the last intron). Upstream and downstream sequences are divided into 100-kb windows. (B) Log2 fold enrichment (x-axis) of leading SNPs for local eQTLs and isoQTLs (permutation FDR < 0.05) for genomic annotations. eQTL enrichments are calculated using a background set of SNPs matched for distance to TSS and allele frequency. IsoQTL enrichments are calculated with respect to a background set of eQTLs matched for distance to TSS and allele frequency. Multiple testing significance is indicated. (*) P < 0.05; (**) P < 0.01; (***) P < 0.001.
