Sickle cell anemia

Definition:

Sickle cell anaemia (SCA) is a recessive genetic disease caused by a single-point mutation in the beta globin gene in codon 6 (Glu6Val) that specifies one of the chains of haemoglobin. The disease is characterized by a chronic haemolytic anaemia with the sickle cells which show abnormal morphology due to the damage of the membrane skeletons and agglutinate under deoxygenated conditions.
