Depression Coagulation Factor Deficiency or Dysfunction. A bleeding disorder may be due to a lack of one or more clotting factors or the result of factors that do not function properly. Deficiency or dysfunction of coagulation factors may have genetic causes (inherited) or may be the result of another disease or condition. The following are a few examples: Inherited.

Factor VIII Factor VIII is produced in liver sinusoidal cells and endothelial cells outside of the liver throughout the body. This protein circulates in the bloodstream in an inactive form, bound to another molecule called von Willebrand factor, until an injury that damages blood vessels occurs.actor VIII (FVIII) is an essential blood-clotting protein, also known as anti-hemophilic factor (AHF). In humans, factor VIII is encoded by the F8 gene.

Von Willebrand Disease Von Willebrand disease (VWD) is a genetic disorder caused by missing or defective von Willebrand factor (VWF), a clotting protein.VWF binds factor VIII, a key clotting protein, and platelets in blood vessel walls, which help form a platelet plug during the clotting process. People with type 1 VWD have a quantitative deficiency of VWF. Levels of VWF in the blood range from 20%-50% of normal. 2  The symptoms are usually mild. 3  Type 2 VWD is found in 15%-30% of patients. 4  People with type 2 VWD have a qualitative deficiency in their VWF.

- People with hemophilia have low levels of either factor VIII (8) or factor IX (9). The severity of hemophilia that a person has is determined by the amount of factor in the blood. The lower the amount of the factor, the more likely it is that bleeding will occur which can lead to serious health problems.

Types of Hemophilia / Haemophilia Hemophilia A and Hemophilia B. There are two main types of hemophilia-Hemophilia A (due to factor VIII deficiency) and Hemophilia B (due to factor IX deficiency). They are clinically almost identical and are associated with spontaneous bleeding into joints and muscles and internal or external bleeding after injury or surgery.

Factor VIII Factor VIII participates in blood coagulation; it is a cofactor for factor IXa which, in the presence of Ca 2+ and phospholipids forms a complex that converts factor X to the activated form Xa.The factor VIII gene produces two alternatively spliced transcripts.actor VIII (FVIII) is an essential blood-clotting protein, also known as anti-hemophilic factor (AHF). In humans, factor VIII is encoded by the F8 gene.

Hemophilia A Males have only 1 X chromosome. If the factor VIII gene is missing on a boy's X chromosome, he will have hemophilia A. For this reason, most people with hemophilia A are male. If a woman has a defective factor VIII gene, she is considered a carrier.

Coagulation Disorders 1 Hypoprothrombinemia is a congenital deficiency of clotting factors that can lead to hemorrhage. 2  Other coagulation disorders include Factor XI deficiency, also known as hemophilia C, and Factor VII deficiency. 3  Hemophilia C afflicts one in 100,000 people and is the second most common bleeding disorder among women. Other coagulation disorders include Factor XI deficiency, also known as hemophilia C, and Factor VII deficiency. 2  Hemophilia C afflicts one in 100,000 people and is the second most common bleeding disorder among women. 3  Factor VII is also called serum prothrombin conversion accelerator (SPCA) deficiency.

- The major types of this condition are hemophilia A (also known as classic hemophilia or factor VIII deficiency) and hemophilia B (also known as Christmas disease or factor IX deficiency).Although the two types have very similar signs and symptoms, they are caused by mutations in different genes.emophilia A and hemophilia B are inherited in an X-linked recessive pattern. The genes associated with these conditions are located on the X chromosome, which is one of the two sex chromosomes.

- Description. 1  This is a bleeding disorder caused by deficiency of clotting factor VIII. 2  The vast majority of cases are inherited but acquired forms do exist, largely in older patients, due to autoantibodies directed against factor VIII or haematological malignancy.

Factor X For example, factor X deficiency may be seen in amyloidosis, where factor X is adsorbed to the amyloid fibrils in the vasculature. Deficiency of vitamin K or antagonism by warfarin (or similar medication) leads to the production of an inactive factor X.

Hemophilia B PrintFriendly. Hemophilia B, also called factor IX (FIX) deficiency or Christmas disease, is a genetic disorder caused by missing or defective factor IX, a clotting protein. Although it is passed down from parents to children, about 1/3 of cases are caused by a spontaneous mutation, a change in a gene.

Human Physiology/Print Version Hemophilia A, the most common type, is caused by insufficient clotting factor VIII. Hemophilia B, the second most common type, is caused by insufficient clotting factor IX. Hemophilia C, in which signs and symptoms are often mild, is caused by insufficient clotting factor XI.

A Recessive Form of the EhlersâDanlos Syndrome Caused by Tenascin-X Deficiency Tenascin-X deficiency causes a clinically distinct, recessive form of the Ehlers–Danlos syndrome. This finding indicates that factors other than the collagens or collagen-processing enzymes can cause the syndrome and suggests a central role for tenascin-X in maintaining the integrity of collagenous matrix.
