Abstract:
Sickle cell hemoglobinopathies are a group of inherited
diseases characterized by an abnormality in the β-chain
of the hemoglobin molecule. Sickle cell disease (SCD) is
found all over the world except in the Far East and in the
Arctic countries. It is most common in Africans and people
of African descent but also occurs in the non-black population
of Saudi Arabia and India.
