(C) Linkage disequilibrium (LD) between the significant SNPs in the Chr17q12-21.1 (magenta) and 21.2 (green) region, highlighting Th1/Th2-associated SNPs (red and blue, respectively), expression quantitative trait loci (eQTLs) in the VDR-binding regions in Chr17q12 21.1 and 21.2 (yellow), and functional asthma SNPs from the literature (cyan). The gene discussed is VDR; the disease is asthma.
