Hemophilia is caused by a mutation or change, in one of the genes, that provides instructions for making the clotting factor proteins needed to form a blood clot. This change or mutation can prevent the clotting protein from working properly or to be missing altogether. These genes are located on the X chromosome.

What deficiency causes hemophilia?

Having too little of factors VIII (8) or IX (9) is what causes hemophilia. A person with hemophilia will lack only one factor, either factor VIII or factor IX, but not both. There are two major kinds of hemophilia: hemophilia A, which is a factor VIII deficiency; and hemophilia B, which is a factor IX deficiency.

How does a person inherit hemophilia?

It almost always is inherited (passed down) from a parent to a child. Both hemophilia A and B are inherited in the same way, because both the genes for factor VIII and factor IX are located on the X chromosome (chromosomes are structures within the body's cells that contain the genes).

How did hemophilia start?

Hemophilia was first introduced to the world as “The Royal Disease” during the reign of Queen Victoria of England. She was a carrier of the hemophilia gene, but it was her son, Leopold, who endured the effects of the bleeding disorder, including frequent hemorrhages and debilitating pain.

What are 5 symptoms of hemophilia?

Does hemophilia go away?

You cannot catch it from someone else. It lasts all of your life and it will not go away. Hemophilia occurs mainly in males but females can carry the gene that causes it and may or may not have bleeding problems. Some children with hemophilia have no family history of the disorder.

What famous person has hemophilia?

The love of Elizabeth Taylor's life and a Shakespearean actor for the ages, Richard Burton starred in 61 films and 30 plays — and was the first Hollywood star to reveal he had hemophilia.

Is hemophilia A or B worse?

Recent evidence suggests that hemophilia B is clinically less severe than hemophilia A, highlighting the need to discuss further therapeutic options for each type of hemophilia. The study, “Haemophilia B is clinically less severe than haemophilia A: further evidence,” was published in Blood Transfusion.

Can a girl get hemophilia?

Hemophilia can affect women, too

When a female has hemophilia, both X chromosomes are affected or one is affected and the other is missing or non-functioning. In these females, bleeding symptoms can be similar to males with hemophilia. When a female has one affected X chromosome, she is a “carrier” of hemophilia.

What foods to avoid if you have hemophilia?

Bleeding in the head and sometimes in the brain which can cause long term problems, such as seizures and paralysis. Death can occur if the bleeding cannot be stopped or if it occurs in a vital organ such as the brain.

Why are females carriers of hemophilia?

A female who inherits one affected X chromosome becomes a “carrier” of hemophilia. She can pass the affected gene on to her children. In addition, a female who is a carrier sometimes can have symptoms of hemophilia. In fact, some doctors describe these women as having mild hemophilia.

Does hemophilia skip a generation?

Fact: Due to the genetic inheritance patterns of hemophilia, the condition can skip a generation, but it doesn't always. Myth: A woman with a bleeding disorder can't have children.

What is the best treatment for hemophilia?

The best way to treat hemophilia is to replace the missing blood clotting factor so that the blood can clot properly. This is typically done by injecting treatment products, called clotting factor concentrates, into a person's vein.

Many patients still die before adulthood due to inadequate treatment. With proper treatment, life expectancy is only about 10 years less than healthy men.

Why isn't there a cure for hemophilia?

There's no cure for hemophilia, but scientists are making progress. They're coming up with ways to put healthy genes into the cells of people with hemophilia so their blood clots normally. Hemophilia has no cure (yet), but changes are on the way.
