Final Paper – Sickle cell disease

Sickle cell disease, also called sickle cell anemia is a group of disorders that affects the molecule in red blood cells that deliver oxygen to the cells. Approximately 100,00 people in America are affected by this disease. Sickle cell disease is an inherited disease, which means it is passed from parents to their children. This disease occurs mainly in people if African, middle eastern, Mediterranean, and Indian decent.

People who are born with sickle cell disease inherit two abnormal hemoglobin genes called sickle hemoglobin, or hemoglobin S. Normal red blood cells are round and flexible but in a person with sickle cell disease their blood cells are crescent or sickle shaped and they are not flexible. The sickle-shaped cells can stick to the wall of the blood vessel and cause a blockage that can stop or slow the flow of blood. The blockage of blood prevents oxygen from reaching nearby tissues. Sickle cell disease is not contagious. It occurs when a child inherits two hemoglobin S genes, one from each parent. In the united states, about 2,000 babies are born with sickle cell disease each year.

Children who only inherit one hemoglobin S gene have sickle cell trait, they do not have sickle cell disease. People with sickle cell trait do not suffer any side effects that people who have sickle cell disease suffer from. Someone who has sickle cell trait carries one…
