Genetic Polymorphism of Basic Proteins from Parotid Saliva

Edwin A. Azen 1

1 Department of Medicine, University of Wisconsin, Madison 53706

In a study of 90 randomly chosen parotid salivas from Blacks three phenotypes were observed during acid-urea starch-gel electrophoresis. Inheritance was controlled by two codominant alleles at an autosomal locus. Of 101 Caucasians, one had a heterozygous phenotype indistinguishable electrophoretically from that in Blacks. Gene frequencies were: for Blacks, parotid basic protein (Pbl) = 0.84, (Pb2) = 0.16; for Caucasians, (Pbl) ~ 0.995, (Pb2) ~ 0.005.
