Properdin factor B polymorphism in Portugal.
The distribution of properdin factor B (Bf) phenotypes and the corresponding gene frequencies in a population sample from Portugal was investigated by agarose-gel electrophoresis and immunofixation. The following gene frequencies were found in Portugal: BfS = 0.6535, BfF = 0.2775, BfS0.7 = 0.0263, and BfF1 = 0.0427.
