Genetic heterogeneity of S-formylglutathione hydrolase

Abstract
S-formylglutathione hydrolase from erythrocytes has been studied by an electrophoretic technique. Three phenotypes were observed in a number of racial groups. The electrophoretic polymorphism was shown to be the product of two alleles at a single locus termed FGH. The product of the type 2 allele was found to be relatively unstable.
