Sickle cell anemia is a genetic disorder characterized by the production of an abnormal type of hemoglobin called hemoglobin S, which causes red blood cells to assume a sickle or crescent shape. The condition can lead to blocked blood flow, painful joints, delayed growth, and strokes. It is particularly prevalent in individuals of African descent.
