Figure 3. EHH plots for APOL1 haplotypes in Sub-Saharan Africa (A), Yoruba from Nigeria (B), Mandenka from Senegal (C) and Bantu from Kenya (D).
The genome coordinates refer to the GRCh37 human genome version. APOL1 G1 (red) and to a lesser extent G2 (orange) alleles showed an enlarged LD pattern in Sub-Saharan Africa and in Yoruba populations and G2 also exhibited an extended LD pattern in Mandenkas compared to G0 (light blue), suggesting a recent positive selection in West Africa. On the contrary, APOL1 G3 allele (green) did not show conclusive evidence of long LD pattern in the Bantu population.
