Stratification of the individuals into haplotypic groups based on the tree promoter IL10A polymorphisms at positions −592/-819/-1082 yielded the following haplotypes distribution: Hap1 (CCG), Hap2 (ATA), Hap3 (CCA) and Hap4 (ATG) with frequencies that varied from 7% to 38% in both malaria (+) and malaria (−) groups. This evidence concerns the gene NFYB and malaria.
