the finding that the number of gamma-globin genes in beta-thalassemia dna is similar to that in nonthalassemia dna indicates that a deletion of gamma-globin genes can not account for either the inadequate gamma-globin synthesis or indirectly for the decreased or absent beta-globin synthesis in beta-thalassemia cells .
