What is a group of hereditary bleeding disorders in which a blood-clotting factor is missing?

Hemophilia is a group of hereditary bleeding disorders characterized by a deficiency in clotting factors, specifically factor VIII (hemophilia A) or factor IX (hemophilia B). These deficiencies result in prolonged bleeding episodes, especially in response to injury or trauma. Treatment typically involves replacement therapy to restore the missing clotting factor.

A hereditary bleeding disorder that results from lack of clotting factors?

Hemophilia is a hereditary bleeding disorder where a person lacks certain clotting factors, such as Factor VIII or Factor IX. This can result in prolonged bleeding and difficulty forming blood clots, leading to potential serious complications if not managed properly. Treatment often involves replacing the missing clotting factors through infusions.

What protein is missing or defective in hemophilia?

Hemophilia is a genetic disorder caused by a deficiency or defect in clotting factor VIII (hemophilia A) or factor IX (hemophilia B). These clotting factors are essential for blood clot formation, and their deficiency leads to prolonged bleeding and poor clotting ability.

Does hemophilia a and b have the same effects?

For the most part, yes. Both disorders effect clotting, both typically lead to the same types of bleeding and both range from severe to mild. They differ in which protein molecule is missing, but the results are pretty similar. (If your car were missing a tire, there would be some differences that depend on which tire was missing, however the overall effect would be pretty similar regardless of which tire was gone.)

Hemophilia is a genetic disorder that?

impairs the blood's ability to clot properly due to missing or reduced levels of clotting factors, leading to prolonged bleeding episodes. It is inherited in an X-linked recessive pattern, primarily affecting males. Treatment involves replacement of the missing clotting factors through infusions.

Is an x-linked recessive bleeding disorder caused by a missing coagulation factor?

Yes, the disorder you are referring to is hemophilia A, which is caused by a deficiency or missing factor VIII in the blood. This results in impaired blood clotting and leads to prolonged bleeding after injury or surgery. It is inherited in an X-linked recessive pattern, meaning it predominantly affects males.

Excessive bleeding caused by congenital lack of factor VII or IX?

The excessive bleeding is likely due to a lack of clotting factors that help the blood to clot properly. Factor VII and IX are both crucial in the coagulation cascade and their deficiency can lead to prolonged bleeding episodes. Treatment may involve replacing the missing clotting factor through infusion to help control bleeding.

If a person's blood was missing platlets what process could not take place?

If a person's blood was missing platelets, the process of blood clotting would be impaired. Platelets are necessary for forming blood clots to stop bleeding when there is an injury to a blood vessel. Without platelets, the body would have difficulty forming clots, leading to excessive bleeding.

Why do Hemophiliacs have trouble clotting their blood after injury?

When a hemophiliac has a cut, the air will dry the blood into something of a temporary a scab, but the patient is missing coagulation factors. They do not have something called fibrin that causes an actual clotting to occur. This means a real scab is not formed, and any little touch can cause the cut to begin bleeding again.

When someone can't stop bleeding?

There are various causes of slow blood clotting. A rare, but fairly well known condition, is Hemophilia. A person with Hemophilia is called a Hemophiliac. Only about 400 babies with the condition are born each year in the US. Most of the disorders in the body's ability to form blood clots to stop bleeding involve an hereditary absence of a clotting factor in the blood.Clotting factors are proteins carried in the blood that help form blood clots. They form the clots working with platelets, cells that were formed in the bone marrow, that are also in the blood. The platelets stick together to stop up an injured blood vessel with a clot that is held together with the help of the clotting factor proteins. Hemophiliacs can be helped by injections or intravenous infusions to replace the missing clotting factors.

What treatments are for hemophilia?

Hemophilia is treated by replacing the missing clotting factors intravenously.

Deficiencies of what could cause abnormally slow blood clotting time?

Slow clotting time means that bleeding takes a longer time to stop. It could be caused by - platelet deficiency or, - insufficient/missing clotting factors - anticoagulant therapy Platelets (normally) are tiny disc-shaped fragments of a big cell (megakaryocyte). They form a temporary plug over the injury site. They also release certain chemicals which help with coagulation if the plug is not enough to stop the bleeding. The condition, in what the absolute platelet numbers are less than sufficient, is called Thrombocytopenia. That could be the result of either the - bone marrow does not make enough platelets (leukaemia, radiotherapy), or - the platelets are destructed faster than the bone marrow makes them (immune disorders, drug therapy). It also could the caused by - viral infections, - Disseminated intravascular coagulation disease - Vitamin B12/folic acid deficiency - menstruation. Clotting factors are chemicals made mostly by the liver and some by the platelets. The clotting factors are either twelve or thirteen in numbers, (depending on how number V, Proaccelerin, and number VI, Accerelin is included in the count), include four factors that the liver can only make if there is enough Vitamin K in the body. Therefore, Vitamin K deficiency could also be one reason. Certain bleeding disorders can interfere with clotting. They might be caused by: - liver or renal disease, and again, - Vitamin K deficiency, - autoimmune diseases (Acquired Haemophilia, Acquired von Willebrand disease) - Genetic disorders (where certain clotting factors are not made: Von Willebrand disease, Haemophilia A, and Haemophilia B, the Christmas disease) Anticoagulant therapy - Warfarin - Heparin - Aspirin also do prolong the clotting time.
