title: Genetic polymorphism of PIF proteins in a Japanese population.
abstract: Phenotype and gene frequencies of PIF (parotid isoelectric focusing variant) were determined in a series of individuals from eastern Japan. Among 422 unrelated individuals examined, 391 (92.66%) of PIF+ and 31 (7.34%) of PIF- phenotypes were observed; the gene frequencies were PIF+ = 0.729 and PIF- = 0.271.
