The worldwide incidence of hemophilia A is approximately 1 case per 5000 males, with approximately one third of affected individuals not having a family history of the disorder. The prevalence of hemophilia A varies with the reporting country, with a range of 5.4-14.5 cases per 100,000 males.
How common is hemophilia in Europe?
The global incidence of haemophilia is approximately 1 per 4,000–5,000 male births; in a given year, approximately 400 boys are born with haemophilia in Europe .
Where can hemophilia be found?
Hemophilia 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 . In males (who have only one X chromosome), one altered copy of the gene in each cell is sufficient to cause the condition.
Can a girl have 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.
Can a man pass hemophilia to his son?
No sons of a man with hemophilia will have hemophilia. All daughters of a man with hemophilia will be carriers (called obligate carriers). If a carrier has a son, the son has a 50% chance of having hemophilia.

Is hemophilia on the rise?

Is hemophilia more common in males?
Since males have only a single copy of any gene located on the X chromosome, they cannot offset damage to that gene with an additional copy as can females. Consequently, X-linked disorders such as Hemophilia A are far more common in males.

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).
What are the types of hemophilia?

How do hemophiliacs stop bleeding?

These three steps are usually sufficient to stop bleeding from minor cuts.
Can hemophiliacs get pregnant?
