Pf chromosome 13, 1770 kb to 1820 kb. Cheeseman et al [8] described this region as being potentially important to the evolution of artemisinin-resistant Pf parasites in Southeast Asia. Of the 1355 SNPs in this 50-kb region, more than 20 exhibit high regional specificity (predominantly in SEA with high FST (>0.1) and low MAF (<30%)) and at least 10 may have spread or are currently spreading to other regions (high MAF and low FST). Gene Pf3D7_1344700 (see Supplementary Figure 2D) contains an example of both: a SNP with high regional specificity (position 1 793 121, labelled as SNP 1 in [8], Supplementary Figure 2E) and one moving towards global fixation (position 1 794 574).
