G6PD and malaria: In contrast to those studies that showed that only female heterozygous individuals were protected against malaria, (Luzzatto, 2015; Uyoga et al., 2015) our study revealed that both male hemizygous individuals and phenotypically deficient female individuals (heterozygotes with G6PD value <2.7 U/gHb and homozygotes) could provide the host protection against malaria through decreasing the parasite density (Figure 1c).
