WebAbstract. Sickle cell anaemia (SCA) is the consequence of abnormal haemoglobin production due to an inherited point mutation in the β-globin gene. The resulting haemoglobin tetramer is poorly soluble when deoxygenated, and when this is prolonged, intracellular gelation of sickle haemoglobin occurs, followed by haemoglobin … WebOther types of sickle cell disease. Less common types of SCD include HbSD, HbSE, and HbSO. These happen when someone inherits 1 gene for hemoglobin S from 1 parent and a gene for another abnormal hemoglobin (D, E, or O) from the other parent. 2. People with HbSD have moderate anemia and occasional pain episodes.
