Properdin Factor B (Bf) Polymorphism in Norway

Abstract
Bf phenotype distribution and Bf allele frequencies in samples of the Norwegian population and the Lappish minority of Norway are presented. BfS in Norwegians was 0.817 and 0.888 in Lapps. The difference is statistically significant. Possible explanations of this difference are discussed. Bf allele frequencies of Norwegians are similar to those of Germans, while differing from frequencies found in USA whites.
