GSTM1 and malaria: Similarly, and as expected in hemoglobinopathies and anemic malaria, significant differences were observed for Hb and PLT level between several Hb genotype groups with and without malaria for example for Hb there was significant differences between HbAA- vs HbAA+ (P = 0.03) and HbSS- vs HbAA- (P < 0.0001).
