title: Beta-globin gene polymorphism in Saudis--triple Hpa I fragments.
abstract: In an attempt to investigate beta-globin gene polymorphism in the Saudi population, DNA samples were analysed using restriction endonucleases, Mst II and Hpa I. Both beta A and beta S genes showed extensive polymorphism and were found to be linked to 13.0 kb, 7.6 kb, 7.0 kb, and 5.6 kb Hpa I fragments. Three DNA samples out of a total of 436 analysed, had beta-globin gene linked to three Hpa I fragments of the sizes 13.0 kb, 7.6 kb, and 5.6 kb. In this paper we present our findings and discuss the possibility of multiple beta-globin loci.
