Human Properdin Factor B

Abstract
Two populations of Niger including a nomad group (Peuls) and a sedentary one (Djerma-Sonrais) were investigated in the study of Bf [properdin factor B] polymorphism. There are no significant differences between the 2 groups and the deduced mean allele frequencies are: BfS = 0.3932; BfF = 0.5097; BfS 0.7 = 0.0194 and BfF1 = 0.0777. Some comparative studies are presented with other Negroid populations so far reported.
