ou cant prevent Fanconi anemia (FA) because its an inherited disease. If a child gets two copies of the same faulty FA gene, he or she will have the disease.

He or she also can explain the choices that are available to you. If youre already pregnant, genetic testing can show whether your child has FA. In the United States, Ashkenazi Jews (Jews of Eastern European descent) are at higher risk for FA than other ethnic groups. For Ashkenazi Jews, its recommended that prospective parents get tested for FA-related gene mutations before getting pregnant. Preventing Complications If you or your child has FA, you can prevent some health problems related to the disorder. Pneumonia, hepatitis, and chicken pox can occur more often and more severely in people who have FA compared with those who dont. Ask your doctor about vaccines for these conditions. People who have FA also are at higher risk than other people for some cancers. These cancers include leukemia (a type of blood cancer), myelodysplastic syndrome (abnormal levels of all three types of blood cells), and liver cancer. Screening and early detection can help manage these life-threatening diseases.
