hemophilia There are thirteen clotting factors and they all work in sequence to help form a clot. The type of clotting factor that is missing determines what kind of hemophilia you have. The two most common types arehemophilia Aand hemophilia B. In hemophilia A, the missing clotting factor is factor VIII. Hemophilia Ais sometimesreferred to as classical hemophilia. In hemophilia B, the missing clotting factor is factor IX. Hemophilia B is sometimesreferred to as Christmas disease.

- Inherited” means that the disorder is passed from parents to children through genes. People born with hemophilia have little or no clotting factor. Clotting factor is a protein needed for normal blood clotting. There are several types of clotting factors.These proteins work with platelets (PLATE-lets) to help the blood clot.Platelets are small blood cell fragments that form in the bone marrow—a sponge-like tissue in the bones.emophilia can be mild, moderate, or severe, depending on how much clotting factor is in your blood. About 7 out of 10 people who have hemophilia A have the severe form of the disorder. People who don't have hemophilia have a factor VIII activity of 100 percent.

Causes of Hemophilia Hemophilia is an inherited disease. Hemophilia is caused by a defect in one of the genes that determines how the body makes blood clotting factors 8 and 9. These genes are located on the X chromosomes, which determine whether a baby is a boy or girl.8 and F9 Genes. Mutations in the F8 or F9 genes cause hemophilia. Mutations in the F8 gene cause hemophilia A, while hemophilia B is caused by mutations in the F9 gene. The proteins made by these genes play a critical role in the process of blood clotting.

Hemophilia The two main types of hemophilia are A and B. If you have hemophilia A, you're missing or have low levels of clotting factor VIII (8). About 8 out of 10 people who have hemophilia have type A. If you have hemophilia B, you're missing or have low levels of clotting factor IX (9). Rarely, hemophilia can be acquired.

Human Physiology/Print Version Types of von Willebrand Disease. As with many conditions, there are various forms of vWD. Unlike hemophilia, which affects only boys, vWD affects boys and girls equally. In Type 1, the level of von Willebrand factor in the blood is reduced; the level of factor VIII also might be reduced.

Hemophilia: Understanding Genetic Risk - Topic Overview If the father has hemophilia and the mother is a carrier, sons will have a 50% chance of having hemophilia. Daughters will have a 50% chance of having hemophilia and a 50% chance of being a carrier. It is very rare for both parents to have these defective genes.

What is hemophilia? People with hemophilia tend to bleed for longer periods of time after an injury and they are more susceptible to internal bleeding. There are two major types of hemophilia, labeled type A and type B. Hemophilia A is characterized by a lack of clotting factor VIII (8) and accounts for about 90% of hemophilia cases.

What is Hemophilia? Hemophilia is a genetic bleeding disorder that prevents blood from clotting. The body uses the clotting process to stop bleeding. With less clotting ability, people with hemophilia bleed more easily and bleed longer.

- Internal bleeding in the brain is a very serious complication of hemophilia. It can happen after a simple bump on the head or a more serious injury. The signs and symptoms of bleeding in the brain include: 1  Long-lasting, painful headaches or neck pain or stiffness. 2  Repeated vomiting. 3  Sleepiness or changes in behavior.

Alone we are rare. Together we are strong.â¥ Donate Today Hemophilia (Hemo = bleed; philia = tendency) is a general term for a group of rare bleeding disorders. Most forms of hemophilia are rare inherited blood clotting (coagulation) disorders caused by inactive or deficient blood coagulation proteins.

Hemophilia Hemophilia (heem-o-FILL-ee-ah) is a rare bleeding disorder in which the blood doesn't clot normally. If you have hemophilia, you may bleed for a longer time than others after an injury. You also may bleed inside your body (internally), especially in your knees, ankles, and elbows. This bleeding can damage your organs and tissues and may be life threatening.

Hemophilia 1 Hemophilia A and B are inherited in an X-linked recessive genetic pattern, so males are commonly affected while females are usually carriers of the disease.  Hemophilia A is caused by a deficiency of clotting Factor VIII, while hemophilia B (also called Christmas disease) results from a deficiency of Factor IX.

What is Hemophilia? The gene that causes hemophilia is often linked to a person’s sex. Males with the altered gene will have symptoms while females may or may not have symptoms. The chances of inheriting the gene also depend on which parent has the gene and if the child is male or female. There are 3 types of hemophilia: Hemophilia A: Caused by low levels of clotting factor VIII (clotting factor 8). This is the most common type of hemophilia. Hemophilia B: Caused by low levels of clotting factor IX (clotting factor 9).

Hemophilia A and B The extent of these symptoms depends on the hemophilia type (A or B) and severity (mild, moderate, or severe). Persons with mild hemophilia (<6% – 49% factor level) may have excessive bleeding after dental procedures, accidents, or surgery, but do not typically have spontaneous bleeds as in severe hemophilia.

Overview The clotting process is encouraged by certain blood particles (platelets and plasma proteins). Hemophilia occurs when you have a deficiency in one of these clotting factors. Hemophilia is inherited. However, about 30 percent of people with hemophilia have no family history of the disorder.

Facts This means that males only have one copy of most of the genes on the X chromosome, whereas females have 2 copies. Thus, males can have a disease like hemophilia if they inherit an affected X chromosome that has a mutation in either the factor VIII or factor IX gene.

- Hemophilia, which isn't very common, mostly affects guys. In rare cases, girls can have the disease and get bleeding problems similar to the ones boys have. When most people get a cut, the body naturally protects itself. Sticky cells in the blood called platelets go to where the bleeding is and plug up the hole.

hemophilia a group of hereditary bleeding disorders characterized by a deficiency of one of the factors necessary for coagulation of the blood. The two most common forms of the disorder are hemophilia A and hemophilia B. Hemophilia A (classic hemophilia) is the result of a deficiency or absence of antihemophilic factor VIII.

Hemophilia A 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. According to the US Centers for Disease Control and Prevention, hemophilia occurs in approximately 1 in 5,000 live births. There are about 20,000 people with hemophilia in the US. All races and ethnic groups are affected. Hemophilia A is four times as common as hemophilia B while more than half of patients with hemophilia A have the severe form of hemophilia.

Overview Hemophilia is a rare disorder in which your blood doesn't clot normally because it lacks sufficient blood-clotting proteins (clotting factors). If you have hemophilia, you may bleed for a longer time after an injury than you would if your blood clotted normally. Small cuts usually aren't much of a problem. The greater health concern is deep bleeding inside your body, especially in your knees, ankles and elbows. That internal bleeding can damage your organs and tissues, and may be life-threatening. Hemophilia is an inherited (genetic) disorder.
