Fanconi anemia
Fanconi anemia (FA) is a rare genetic disease that affects children and adults from all ethnic backgrounds. Named for Swiss pediatrician, Guido Fanconi, it is one of the inherited anemias that leads to bone marrow failure (aplastic anemia). It is a recessive disorder: if both parents carry a defect (mutation) in the same FA gene, each of their children has a 25% chance of inheriting the defective gene from both parents. When this happens, the child will have FA. Approximately 1,000 persons worldwide presently suffer from the disease.Because of the failure of the components of the blood - white and red blood cells and platelets - the body cannot successfully combat infection, fatigue or spontaneous hemorrhage or bleeding. Bone marrow transplantation is the accepted treatment to repair the hematological problems associated with FA. Patients face an increased risk of acquiring cancer and other serious health problems throughout their lifetime.
Many patients eventually develop acute myelogenous leukemia (AML). Older patients are extremely likely to develop head and neck, esophogeal, gastrointestinal, vulvar and anal cancers. Patients who have had a successful bone marrow transplant and, thus, are cured of the blood problem associated with FA still must have regular examinations to watch for signs of cancer. Many patients do not reach adulthood.
The overarching medical challenge that Fanconi patients face is a failure of their bone marrow to produce blood cells. In addition, Fanconi patients normally are born with a variety of birth defects. For instance, 90% of the Jewish children born with Fanconi's have no thumbs. A good number of Fanconi patients have kidney problems, trouble with their eyes, developmental retardation and other serious defects.
