Description:
The delta (HBD) and beta (HBB) genes comprise the two adult globin genes on the beta globin locus on chromosome 11. The expression of HBB is greater than that of HBD resulting in the production of HbA (α2β2), which constitutes about 97% of the total haemoglobin. Two delta chains together with two alpha chains form HbA2 (α2δ2), the minor fraction of adult haemoglobin (generally 3%). Mutations in HBB associate with the most common inherited β-globin gene disorders, such as β-thalassaemia and sickle cell disease. Mutations in HBD are assumed to be physiologically reduntant with clinical relevance solely in the diagnosis of β-globin disorders. The globin genes are arranged as 5'-ε(HBE)-Gγ(HBG2)-Aγ(HBG1)-ψβ(HBBP1)-δ(HBD)-β(HBB)-3' on the β-globin locus. HBBP1 is classified as a pseudogene, characterized by the presence of several stop codons that were once thought to be mutations. Polymorphisms in this intergenic region (HBD-HBBP1) associated with HbF levels in sickle cell patients.
