Patients with TI require blood ... WebAims: Haemoglobin A 2 (HbA 2) consists of two globin chains, α and β. Alterations in any of these genes influences the level of HbA 2. Here, we present cases of structural Hb variants and thalassaemias which present either alone or together and reduce the level of HbA 2 at varying degrees.

The discovery that hemoglobin F alleviated the symptoms of sickle cell disease occurred in 1948. Janet Watson observed that red blood cells from infants with the disease took longer to sickle and did not deform as much compared to their mother's cells, which carried the disease trait.
