CSF2 and malaria: Carriage of the CSF2 AC haplotype was also protective against malaria infections (P = 0.0045) relative to wild-type haplotype (GT), while co-inheritance of the CSF2 GC/GT diplotype showed a non-significant trend towards a lower risk of malaria (P = 0.1108) compared to wild type (GT/GT) (Table 4).
