Haplotyping of the beta-globin gene cluster was performed on DNA sampl
es from 110 Azerbaidzhanian beta-thalassemic patients and their famili
es. During this study, we found 18 different haplotypes and determined
the frequency of their occurrence. Nine of these haplotypes have neve
r been observed earlier in the studied population. One of the haplotyp
es was found only in beta-thalassemia alleles. Several haplotypes were
associated with beta-thalassemia mutations found earlier in Azerbaidz
han.
