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.

Coagulation Disorders Some common coagulation disorders are: 1  Hemophilia, or hemophilia A (Factor VIII deficiency), an inherited coagulation disorder, affects about 20,000 Americans. 2  Christmas disease, also known as hemophilia B or Factor IX deficiency, is less common than hemophilia A with similar in symptoms.

Alone we are rare. Together we are strong.â¥ Donate Today Another form of the disorder, known as acquired hemophilia, is not caused by inherited gene mutations. This rare condition is characterized by abnormal bleeding into the skin, muscles, or other soft tissues, usually beginning in adulthood.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.

Facts The following two are the most common: 1  Hemophilia A (Classic Hemophilia) This type is caused by a lack or decrease of clotting factor VIII. 2  Hemophilia B (Christmas Disease) This type is caused by a lack or decrease of clotting factor IX.

Treatment Blood Clotting Factor The best way to treat hemophilia is to replace the missing blood clotting factor so that the blood can clot properly. This is done by injecting commercially prepared clotting factor concentrates into a person’s vein.

- Hemophilia A, also known as factor VIII deficiency, is the most common type of hemophilia. About 80% of people with hemophilia have hemophilia A. However, about 20% of people have hemophilia B (factor IX deficiency).

Frequently Asked Questions Hemophilia is one of the most common bleeding disorders and is classified as follows: 1  Hemophilia A – Also called classic hemophilia, it is 4 times more common than hemophilia B, and it occurs when factor VIII levels are deficient.

Hemophilia There are two types of inherited hemophilia: 1  Type A, the most common type, is caused by a deficiency of factor VIII, one of the proteins that helps blood to form clots. 2  Type B hemophilia is caused by a deficiency of factor IX.emophilia is a rare hereditary (inherited) bleeding disorder in which blood cannot clot normally at the site of a wound or injury. The disorder occurs because certain blood clotting factors are missing or do not work properly. This can cause extended bleeding from a cut or wound.

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).

- Genetics. The two main types of hemophilia are caused by gene mutations that affect the levels of clotting factors in the blood. Mutation of the FVIII gene leads to hemophilia A, also called classic hemophilia, while a mutations in the FIX gene leads to hemophilia B, also called Christmas disease.

- 1 Hemophilia A, the most common type, is caused by insufficient clotting factor VIII. 2  Hemophilia B, the second most common type, is caused by insufficient clotting factor IX.3  Hemophilia C, in which signs and symptoms are often mild, is caused by insufficient clotting factor XI. Hemophilia A, the most common type, is caused by insufficient clotting factor VIII. 2  Hemophilia B, the second most common type, is caused by insufficient clotting factor IX.

- Q. What is hemophilia and how many people have it? A. It is a bleeding disorder that results from a deficiency in a substance that allows the blood to coagulate or clot. It affects one in every 5,000 male babies born in this country, but occurs in women only rarely.

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 Hemophilia A is the most common type of hemophilia, and it’s caused by a deficiency in factor VIII. According to the National Heart, Lung, and Blood Institute (NHLBI), eight out of 10 people with hemophilia have hemophilia A. Hemophilia B, which is also called Christmas disease, is caused by a deficiency of factor IX.

Hemophilia Hemophilia A and B are more common in males than females because of the genetic transmission. Hemophilia C is an autosomal inherited form of the disease, meaning that it affects males and females equally. This is because the genetic defect that causes this type of hemophilia is not related to sex chromosomes.

- Haemophilia A (clotting factor VIII deficiency) is the most common form of the disorder, present in about 1 in 5,000–10,000 male births. Haemophilia B (factor IX deficiency) occurs in around 1 in about 20,000–34,000 male births.

Gene Therapy May Let Hemophilia Patients Skip Meds Hemophilia arises from an inherited gene mutation that impedes the ability to produce normal levels of a blood clotting factor. This leaves patients vulnerable to spontaneous bleeding or excessive bleeding from injuries. The disorder has two major forms: hemophilia A, which affects about 80 percent of all patients, and hemophilia B. Hemophilia B occurs in about 1 in 30,000 boys and men, George said. Because the recessive gene disorder is linked to the X chromosome, women can be carriers but are unaffected by the condition.

Hemophilia Symptoms Approximately 18,000 people in the United States have this disorder. People with hemophilia may bleed for a longer period of time following an injury or accident; they may also bleed internally, especially in the joints (such as the knees, ankles, and elbows). Common symptoms of hemophilia include bleeding and bruising.

Hemophilia Hemophilia is a bleeding disorder that slows the blood clotting process. People with this condition experience prolonged bleeding or oozing following an injury, surgery, or having a tooth pulled. In severe cases of hemophilia, continuous bleeding occurs after minor trauma or even in the absence of injury (spontaneous bleeding).

Information for Women Bleeding from circumcision is the most common cause of bleeding among babies with hemophilia. It can occur days after the procedure is done and, for babies who have not been diagnosed already, often leads to the initial hemophilia diagnosis. In the baby who may have hemophilia, avoid circumcision if possible.
