Sickle cell disease is an inherited blood disorder that affects more than 90,000 Americans, mostly of African descent. The condition arises from a genetic defect that alters the structure of hemoglobin, the oxygen-carrying protein found in red blood cells. The modified hemoglobin causes normally round red blood cells to become stiff, sticky, and sickle-shaped. The deformed cells can block blood flow, causing severe pain, organ damage, and stroke.
