Plot includes a display of linkage disequilibrium (r2) based on HapMap Yoruba (YOR) data and positions of SNPs along chromosome 1. SNPs shown in gray were not in HapMap. Recombination rates are depicted by the blue line within the plot. Association analysis P-values were adjusted for age and global west African ancestry and visualized using LocusZoom (http://csg.sph.umich.edu/lo…).
