Table 3 Comparison of PC1/2 between patients with WT and a pfk13 NS-mutation in Asia. Metric is the fold increase of PC1/2 in mutants vs. wild type. Only mutations with n ≥ 5 are shown. With only two exceptions (K189T and K438N), all patients that carried parasites with the indicated pfk13 mutant codon showed a PC1/2 significantly different from those that carried WT parasites
