WebPathophysiology of Sickle Cell Disease. Hemoglobin (Hb) molecules consist of polypeptide chains whose chemical structure is genetically controlled. The normal adult hemoglobin molecule (Hb A) consists of 2 pairs of chains designated alpha and beta. Normal adult blood also contains ≤ 2.5% hemoglobin A2 (composed of alpha and delta chains) and ... WebWe know that coping with an inherited condition like Sickle Cell Disease, Thalassaemia or Haemophilia, in addition to the usual stresses in life, can be especially challenging and that sessions with a psychologist can be helpful in getting through a difficult period.
