Sickle Cell Anemia

The sickle cell disease is an inherited blood disorder that affects red blood cells. People with sickle cell have red blood cells that have mostly hemoglobin's, Sometimes these red blood cells become sickle-shaped or crescent shaped and have trouble going through small blood vessels. When sickle-shaped cells block small blood vessels, less blood can get to that part of the body. Tissue that does not get a normal blood flow eventually becomes damaged.This is …

…the disease. The insolubility of deoxygenated (reduced) sickle hemoglobin is the basis of two rapid diagnostic laboratory tests for sickle cell anemia. Scientists recently have had some limited success in using genetic engineering techniques to get good copies of the beta globin gene into people with sickle cell anemia. If they can succeed in this endeavor, people with the disease may be cured but will still be able to pass the genes onto their offspring.
