The site of a PvuII restriction fragment length polymorphism (RFLP) of the human glucose-6-phosphate dehydrogenase (G6PD) gene has been located in intron V, 60 bp upstream of G6PD exon VI. A population survey shows this RFLP to be specific for African populations, with frequencies of the rarer allele (PvuII type 2 site present) of 0.32-0.40 in Kenyans, Nigerians, Zambians, and West Indians. This allele has not been found in the European, Asian and Middle Eastern populations studied. Such population-specific markers may be useful in the study of population affinities and may provide insight into prehistoric migrations of peoples.
