This video from Medic Tube gives an overview of the genetic causes behind hemophilia. The narrator explains that it’s very rare for females to have hemophilia because they need to inherit the faulty X gene from both of their parents, whereas males only need to inherit one faulty X gene to develop the disease.

In some rare cases of hemophilia, a genetic mutation occurs and the patient develops the disease even though neither parent has the faulty gene.

Acquired hemophilia can affect babies after they’re born, and develops when their blood forms antibodies that block factors from working. Pregnant women and people with autoimmune diseases like rheumatoid arthritis are more at risk of developing acquired hemophilia.
