In order to clarify the reasons for the reduced Hb A2 levels in Sardinian delta beta-thalassemia, we characterized, both by cloning and sequence analysis and by direct sequencing of amplified DNA, the delta-globin gene from an individual of Sardinian descent who is a compound heterozygote for the beta zero-thalassemia codon 39 (C-->T) nonsense mutation and the Sardinian delta beta-thalassemia [codon 39(C-->T)/-196(C-->T)A gamma]. The analysis of the delta-globin gene from the delta beta-thalassemia chromosome revealed an entirely normal sequence. The defective function of the delta-globin gene in this determinant is thus likely related to a suppressive effect of the in cis nondeletional high persistence of fetal hemoglobin mutation of the A gamma gene, probably resulting from an increased capability of the relative promoter to interact with the locus control region.
