Hemoglobin subunit delta is a protein that in humans is encoded by the HBD gene.[3]

Function

The delta (HBD) and beta (HBB) genes are normally expressed in the adult: two alpha chains plus two beta chains constitute HbA, which in normal adult life comprises about 97% of the total hemoglobin. Two alpha chains plus two delta chains constitute HbA2, which with HbF comprises the remaining 3% of adult hemoglobin. Five beta-like globin genes are found within a 45 kb cluster on chromosome 11 in the following order: 5' - epsilongamma-Ggamma-Adeltabeta - 3'.[4]

Clinical significance

Mutations in the delta-globin gene are associated with Delta-thalassemia.[4]
