From these results, we may conclude that the inheritance of a mild beta-thalassemia allele such as the beta+ IVS-I nt 6 mutation, in the homozygous or heterozygous state, the coinheritance with homozygous beta zero-thalassemia of the -158 (C----T) G gamma gene promoter mutation and the presence of heterozygous beta-thalassemia/triple alpha-globin gene arrangement are the most common reasons accounting for the development of attenuated forms of beta-thalassemia in Puglia.
