Population genetic data on properdin factor B (Bf) in Northern Germany

Abstract
Properdin factor B phenotypes were determined in 1,112 unrelated individuals and in 151 mother/child combinations from Northern Germany. Gene frequencies were: F = 0.1960, S = 0.7905, F1 = 0.0072, S1 = 0.0063. The data of the mother/child combinations are in full accordance with the postulated gene model.
