Genetic Variants of Human C3 and Properdin Factor B in a Population from Tunisia

Abstract
Bf and C3 type determinations have been performed in a population from Tunisia. The corresponding allele frequencies are as follows: BfsS = 0.6173, BfF = 0.2813, BfS0.7 = 0.0827, BfF1 = 0.0187 and C3S = 0.8326, C3F = 0.1524, C3S0.4 = 0.0086, C3F rare’ = 0.0064. According to these values, the Tunisian population seems to be situated between Caucasoid and Negroid populations.
