Decay of LD for the APOL1 Variants in African Populations

Plots of r² estimates between polymorphic sites against the physical distance across a 30 kb region flanking the last exon of APOL1 in the six African populations. The r² estimates are colored in orange for all pairwise estimates within the G3-associated SNPs. In each plot, the fitted nonlinear regression line (solid line) and its 95% prediction interval (dashed line) were plotted on the basis of all r² estimates except for the orange dots.
