a Manhattan plot of −log10 P values of the SNP-based association analysis of morning plasma cortisol (n = 25,314). The locus on chr14 spans SERPINA6 and SERPINA1 genes; no other loci reached genome-wide significance. b, c Zoomed in Manhattan plot (LocusZoom plot) of −log10 P values of the SNP-based association analysis of morning plasma cortisol (n = 25,314). These show two (of the four) LD blocks (r2 > 0.3) in this locus
