[Genetic polymorphism of the second component of human complement (C2) in the Han Nationality in Wuhan district of China].
A total number of 231 unrelated Chinese (Han Nationality) were investigated for C2 polymorphism by hemolytic overlay technique after polyacrylamide gel isoelectric focusing on plasmas. The following phenotype distributions were observed: C2C, 216; C2BC, 9; C2AC, 5; and C2A, 1. The gene frequencies calculated from these phenotypes were as follows: C2*A, 0.015; C2*B, 0.019; C2*C, 0.965. The C2 phenotypic frequency distributions were in agreement with those expected from Hardy-Weinberg equilibrium.
