Genetic polymorphism of human plasminogen

Abstract

Using isoelectric focusing (IEF) in polyacrylamide gel of neuraminidase-treated serum or plasma samples and immunofixation or caseinolytic overlay after urokinase activation of gels, a common genetic polymorphism in human plasminogen has been delineated. Two alleles PLGN*A and PLGN*B, were observed with gene frequencies in whites of .69 and .30; in Orientals of .96 and .03; and in blacks of .80 and .18. Several rare alleles were also found. The distribution of phenotypes fits the Hardy-Weinberg equilibrium. Inheritance is autosomal codominant and fits the expectations of Mendelian inheritance. There is fetal synthesis, but no transplacental passage of plasminogen in either direction.
