Summaries for Hemophilia a

NIH Rare Diseases : 53 Hemophilia A is an inherited bleeding disorder in which the blood does not clot normally. People with hemophilia A will bleed more than normal after an injury, surgery, or dental procedure. This disorder can be severe, moderate, or mild. In severe cases, heavy bleeding occurs after minor injury or even when there is no injury (spontaneous bleeding). Bleeding into the joints, muscles, brain, or organs can cause pain and other serious complications. In milder forms, there is no spontaneous bleeding, and the disorder might only be diagnosed after a surgery or serious injury. Hemophilia A is caused by having low levels of a protein called factor VIII. Factor VIII is needed to form blood clots. The disorder is inherited in an X-linked recessive manner and is caused by changes (mutations) in the F8 gene. The diagnosis of hemophilia A is made through clinical symptoms and specific laboratory tests to measure the amount of clotting factors in the blood. The main treatment is replacement therapy, during which clotting factor VIII is dripped or injected slowly into a vein. Hemophilia A mainly affects males. With treatment, most people with this disorder do well. Some people with severe hemophilia A may have a shortened lifespan due to the presence of other health conditions and rare complications of the disorder.

MalaCards based summary : Hemophilia a, also known as factor viii deficiency, is related to factor viii deficiency and acquired hemophilia a. 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 Tranexamic Acid and Triamcinolone have been mentioned in the context of this disorder. Affiliated tissues include testes, liver and bone, and related phenotypes are joint swelling and arthralgia

OMIM : 57 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)

UniProtKB/Swiss-Prot : 74 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.
