title: [Genetic polymorphism of complement component six (C6) in five Han subpopulations].
abstract: By using polyacrylamide gel isoelectric focusing followed by immunoassay, the polymorphism of Complement Component Six (C6) was investigated in five Han subpopulations in China. The following gene frequencies were obtained Zhengzhou Han: C6*A 0.4521, C6*B 0.5228, C 6*B2 0.0183, C6*R 0.0068; Lanzhou Han: C6*A 0.4612, C6*B 0.5218, C6*B2 0.0170; Huhhot Han: C6*A 0.4452, C6*B 0.5286, C6*B2 0.0214, C6*R 0.0048; Xi'an Han: C6*A 0.4899, C6*B 0.4874, C6*B2 0.0126, C6*R 0.0101; Hakka of Meizhou, Guangdong Province: C6*A 0.4569, C6*B 0.5152, C6*B 0.0279 (C6*R is the frequency of rare alleles).
