Genetic Cause • Hemophilia is a recessive sex-linked disorder. • The mutated gene that accounts for hemophilia is located on the X chromosome. • A mutation in the F8 gene causes Hemophilia A, and a mutation in the F9 gene causes Hemophilia B. • These mutations result in an absence of several proteins required for blood clotting. singularityhub.com
Treatment • There is no cure for hemophilia and no way to prevent it. However, patients can receive injections of donated, synthetic, or recombinant forms of plasma. • Human Factor VII concentrate: plasma-derived Factor VII is made from donor plasma • Recombinant Factor VIII concentrate: recombinant plasma containing albumin • Porcine Factor VIII concentrate • Prothrombin Complex Concentrate: contains prothrombin, Factor X and Factor IX • Coagulation Factor IX concentrate treats Hemophilia B • Cryoprecipitate: contains Factor VIII and fibrinogen • Synthetic plasma, DDAVP • High amounts of estrogen or progesterone www.pathguy.com
Tests and Screenings • Blood tests can be used analyze the amount of coagulation factors present (or absent) in the blood, as well as clotting rate. • Chronic Villus Sampling (CVS) or Amniocentesis can determine pre-natal hemophilia. • Physical examination • Family history/pedigree analysis www.sillyjokes.co.uk
Percentage of Population • One in every 10,000 males (approximately 0.01%) has Hemophilia A, and it is extremely rare for a woman to have Hemophilia A. • One in every 60,000 males (approximately 0.002%) has Hemophilia B, and it is extremely rare for a woman to have Hemophilia B. • Hemophilia occurs in all world populations, regardless of race/ethnicity or environment/region. www.humanillnesses.com
Societal Issues • Hemophilia is culturally accepted in most societies, and there are many support groups, fundraisers, and educational programs for hemophiliacs and their families. • In the United States, there are organizations such as the National Hemophilia Foundation and the Hemophilia Federation of America. • There is also a World Federation of Hemophilia. www.hemophiliavillage.com
