FA is a rare, inherited disease that is caused by a gene defect to the CD34+ cells. It primarily affects an individual's bone marrow, resulting in decreased production of blood cells. The lack of white blood cells affects an individual's ability to fight infections, the lack of platelets may result in bleeding, and the lack of red blood cells usually leads to anemia. FA is typically diagnosed in childhood, and there is a high fatality rate. This study will use two methods to collect, purify, and store participant's CD34+ cells for future use in case of severe bone marrow failure. The collected cells will also be used by researchers to better understand the causes of FA and to possibly develop new treatments.
