What is Type B Christmas disease?

Christmas disease, also called hemophilia B or factor IX hemophilia, is a rare genetic disorder in which your blood doesn’t clot properly. If you have Christmas disease, your body produces little or no factor IX. This leads to prolonged or spontaneous bleeding.

What is hemophilia type B?

Hemophilia B is a rare genetic bleeding disorder in which affected individuals have insufficient levels of a blood protein called factor IX. Factor IX is a clotting factor. Clotting factors are specialized proteins needed for blood clotting, the process by which blood seals a wound to stop bleeding and promote healing.

Is there a cure for hemophilia B?

There is no cure for hemophilia B, but it’s possible for you and your family to learn how to prevent injury and administer your own clotting factor treatments at home. Whether or not you are on home treatment, you should always have replacement clotting factors at home. This is what you will need in case of emergency.

Does hemophilia shorten your life?

Many patients still die before adulthood due to inadequate treatment. With proper treatment, life expectancy is only about 10 years less than healthy men. Overall, the death rate for people with hemophilia is about twice that of the rate for healthy men. For severe hemophilia, the rate is four to six times higher.

What is the difference between hemophilia A and B?

Haemophilia can be defined as a bleeding disorder that is caused by the deficiency of the clotting factors. The differences between Haemophilia A and B are in the low level – Haemophilia A means low levels of factor (8) and Haemophilia B is low levels of factor (9).

Does Queen Elizabeth carry hemophilia?

However, it’s wildly unlikely that modern royal children are at an increased risk for hemophilia. Though Queen Elizabeth II is related to Queen Victoria on her father’s side, there’s no evidence that her children or grandchildren have the illness. And even if they did, they wouldn’t be able to pass the mutation along.

Queen Victoria of England, who ruled from 1837-1901, is believed to have been the carrier of hemophilia B, or factor IX deficiency. She passed the trait on to three of her nine children. Her son Leopold died of a hemorrhage after a fall when he was 30.

Is hemophilia linked to inbreeding?

Though rare in the general population, the frequency of the mutated allele and the incidence of the disorder was greater among the royal families of Europe due to the high levels of royal inbreeding. A case in which the presence of hemophilia B had a particularly significant effect was that of the Romanovs of Russia.

Is hemophilia considered a disability?

Fortunately, hemophilia is included in the Social Security Administration’s (SSA) Blue Book of impairment listings, which means it may be possible to obtain benefits if you meet the requirements of the listing. This condition is included in section 7.08 for disorders of thrombosis and hemostasis.
