Hemophilia B.
Hemophilia is a bleeding disorder that slows down the blood clotting process. People who have hemophilia often have longer bleeding after an injury or surgery. People who have severe hemophilia have spontaneous bleeding into the joints and muscles. Hemophilia occurs more commonly in males than in females.The two most common types of hemophilia are hemophilia A (also known as classic hemophilia) and hemophilia B (also known as Christmas disease). People who have hemophilia A have low levels of a blood clotting factor called factor eight (FVIII). People who have hemophilia B have low levels of factor nine (FIX).The two types of hemophilia are caused by permanent gene changes (mutations) in different genes.
Many years ago, it was refered to as 'the Royal Disease" also the "Bleeding disease". Hemophilia B is also known as Christmas Disease.

Royal Hemophilia is a reference to Hemophilia B, also known as Factor IX (9) deficiency. This is a genetic disorder that can be inherited. Also near 30% of the Hemophilia B cases result from spontaneous mutations and are not inherited at all. That being said, once the mutation has occurred, that individual can pass the mutation on.
