Guidelines for sites linking to mayoclinic.orgThe treatment of hemophilia at Mayo Clinic involves physicians in multidisciplinary treatment teams that may include specialists in hematology, orthopedics, internal medicine, and physical medicine and rehabilitation, along with hemophilia nurses and social workers. Team members collaborate to develop the most appropriate treatment plan for each patient.
In addition, Mayo Clinic routinely performs genetic testing of children with hemophilia and other bleeding disorders. These tests are particularly useful for expectant parents and obstetricians and for genetic counseling of newly diagnosed patients.
Each year, Mayo's Comprehensive Hemophilia Center evaluates and cares for about 200 patients. It also assists in managing and caring for another 100 patients annually who come to Mayo Clinic for initial evaluation or consultation.
Mayo Clinic specialists determine which bleeding disorder affects each patient based on the patient's medical history, a physical examination, and specialized blood tests. Hemophilia is usually diagnosed before birth through a blood test or after a baby is born. A family history of bleeding disorders is a strong indicator. Read more about hemophilia diagnosis.
Mayo Clinic's Comprehensive Hemophilia Center treats all bleeding disorders. Although hemophilia is not yet curable, patients can live with the disease with the use of clotting factor concentrates. Read more about hemophilia treatment options.
About 17,000 people in the United States have hemophilia. The blood of a person who has hemophilia, a rare, inherited bleeding disease, lacks a protein important to proper clotting. Sometimes the missing protein is clotting factor VIII (eight, also called antihemophilic factor and thromboplastinogen), sometimes factor IX (nine, also called autoprothrombin I or the Christmas factor). The genes for both factors are present on the X chromosome. Because women have two X chromosomes, they are known as carriers; and they typically have normal blood factor levels. Because men and boys have one X chromosome and one Y chromosome, they are typically those who have hemophilia. Patients usually inherit the abnormal X chromosome from their mothers. Only rarely do women and girls develop the low levels of clotting factors VIII and IX that lead to bleeding symptoms.
