Abstract
Polymorphism of factor H (HF) was investigated in 1060 unrelated Japanese individuals using isoelectric focusing and immunoblotting. Besides 6 different HF types a null type and an unusual type were observed. The family analysis suggested the hereditary occurrence of a new variant allele HF*C. The population data fitted the Hardy-Weinberg equilibrium, assuming that the null allele HF*QO occurs commonly. The allele frequencies were HF*A = 0.407 +/- 0.011, HF*B = 0.491 +/- 0.011, HF*A1 = 0.011 +/- 0.002 and HF*QO = 0.091 +/- 0.006. The HF polymorphism in Japanese was shown to be controlled by the above 4 common alleles.
