title: Properdin factor B(Bf) polymorphism in the population of Veneto, Italy.
abstract: The distribution of Bf phenotypes in the population of Veneto was investigated by agarose gel electrophoresis and immunofixation. In our sample (n = 592), the seven common phenotypes F, S, F-S, S-S0.7, S-F1, F-S0.7, F-F1 were observed and the following gene frequencies calculated: Bf*S = 0.7399; Bf*F = 0.2280; Bf*F1 = 0.0177; Bf*S0.7 = 0.0144. These gene frequencies are compared to those found in other populations. Analysis of 21 mother-child pairs was in agreement with an autosomal codominant inheritance.
