Sickle Cell Anemia: Sickle cell anemia is an inherited blood disorder characterized by red blood cells which are crescent-shaped rather than the normal doughnut shape. These abnormally shaped red blood cells are unable to function normally and tend to undergo premature destruction which leads to anemia. If the genetic defect which causes the condition is inherited from both parents the condition can be quite severe whereas if it is inherited from only one parent, often there are no symptoms. The abnormally shaped red blood cells can cause problems when they clump together and block blood vessels.
Turner Syndrome: Rare chromosome syndrome with one X but no second X or Y chromosome.
