Summaries for Hemophilia a

OMIM : 53 Hemophilia A is an X-linked recessive bleeding disorder caused by a deficiency in the activity of coagulation factor VIII. The disorder is clinically heterogeneous with variable severity, depending on the plasma levels of coagulation factor VIII: mild, with levels 6 to 30% of normal; moderate, with levels 2 to 5% of normal; and severe, with levels less than 1% of normal. Patients with mild hemophilia usually bleed excessively only after trauma or surgery, whereas those with severe hemophilia have an annual average of 20 to 30 episodes of spontaneous or excessive bleeding after minor trauma, particularly into joints and muscles. These symptoms differ substantially from those of bleeding disorders due to platelet defects or von Willebrand disease (193400), in which mucosal bleeding predominates (review by Mannucci and Tuddenham, 2001). (306700)

MalaCards based summary : Hemophilia a, also known as factor viii deficiency, is related to mild hemophilia a and severe hemophilia a, and has symptoms including arthralgia, joint swelling and thromboembolism. An important gene associated with Hemophilia a is F8 (Coagulation Factor VIII), and among its related pathways/superpathways are Response to elevated platelet cytosolic Ca2+ and Collagen chain trimerization. The drugs Thrombin and Benzocaine have been mentioned in the context of this disorder. Affiliated tissues include testes, liver and brain, and related phenotypes are cardiovascular system and homeostasis/metabolism

NIH Rare Diseases : 49 Hemophilia A is a bleeding disorder in which the blood does not clot normally. People with this disorder have prolonged bleeding or oozing after an injury, surgery, or tooth extraction. In severe cases, heavy bleeding occurs after minor injury or even when there is no injury (spontaneous bleeding). Serious complications can result from bleeding into the joints, muscles, brain, or other internal organs. In milder forms there is no spontaneous bleeding, and the disorder may not become apparent until after a surgery or serious injury. Hemophilia A is inherited in an X-linked recessive manner and is caused by changes (mutations) in the F8 gene. The main treatment is called replacement therapy, during which clotting factor VIII is dripped or injected into a vein. Last updated: 3/18/2015

UniProtKB/Swiss-Prot : 71 Hemophilia A: A disorder of blood coagulation characterized by a permanent tendency to hemorrhage. About 50% of patients have severe hemophilia resulting in frequent spontaneous bleeding into joints, muscles and internal organs. Less severe forms are characterized by bleeding after trauma or surgery.
