Properdin factor B polymorphism in Afghanistan.
The distribution of properdin factor B (Bf) phenotypes and gene frequencies was studied in four populations of Afghanistan: Hazaras, Pushtoons, Tajiks and Usbeks. Significant differences between Usbeks and the other three ethnic groups were observed. The distribution of gene frequencies in Usbeks was similar to that of European populations.
