Doctor insights on: Does inbreeding in families cause hemophilia to develop
Not usually: Despite emphasis on hemophilia and royal families, rasputin's influence depended on common relatives among english/russian royalty. The well-known hemophilias are x-linked, passed through normal women with 2 xs to men with one. Inbreeding increases chances for matching up of rare, autosomal recessive mutations in spouses (e.g., cystic fibrosis, tay-sach's diseases). ...Read more
Queen Victoria: She was a new mutation, on the evidence. One of her X-chromosomes when transmitted to her male descendants resulted in their getting the disease. It wasn't just the British royal family; they were intermarried, and the Tsar's failure to produce a healthy heir prevented a constitutional monarchy run by reasonable people in Russia. Random events have grave consequences. ...Read more
My sister has a son with hemophilia, but there is no family history other than that, is this just bad luck?
It dosent: The bleeding is not the cause of this condition but the sign of the disorder. The person with hemophilia lacks some of the factors responsible for clotting. Thus any bleeding lasts for a longer time and is more profound as compared to a person with normal clotting mechanisms. ...Read more
It's not that simple: This isn't sickle cell anemia. A huge variety of different genetic mutations cause hemophilia A. The most common troublesome one is an inversion in intron 22. I'm sorry you had trouble finding an answer to this question, and perhaps you'll enjoy reading up on this complex but fascinating study. ...Read more
Gene on X-chromosome: Hemophilia a is a hereditary bleeding disorder where there is a deficiency in clotting factor viii (factor viii is needed for blood clotting). It is inherited on the x-chromosome (sex-linked). Men only have 1 "x", so if their "x" is mutated, they will have the disease. Women have 2 "x's", so they can have 1 mutated "x" and 1 normal "x", and be a carrier of the disease, with mild or no symptoms. ...Read more
Gene for Factor VIII: Hemophilia a is a hereditary bleeding disorder where there is a deficiency in clotting factor viii (factor viii is needed for blood clotting). It is inherited on the x-chromosome (sex-linked). Men only have 1 "x", so if their "x" is mutated, they will have the disease. Women have 2 "x's", so they can have 1 mutated "x" and 1 normal "x", and be a carrier of the disease, with mild or no symptoms. ...Read more
Yes: Some classes of antibiotics can prolong the prothrombin time, especially when taken with other medications. Your doctor should be aware of all of your medical conditions, all medications (including herbs and vitamins), and any subsequent symptoms. This can be dangerous and needs close monitoring and frequent lab work. ...Read more
My son is 3 and has mild hemophilia A, I took him to the hospital 2 weeks about cause he bumped his head and he got a lump, my concern is that it's not going down what can I do?
Patience: If he was evaluated and the only residual is the goose egg, you may just need to wait it out. When kids form a blood pocket after such an injury, it is located between the skull and a dense layer of scalp that has no regular blood supply. The bleeding stops itself by having a limited space to expand. It can time for the blood to break down and be absorbed. It will sometimes form a calcium deposit. ...Read more
Bleeding cystitis for 2 weeks. I am also a symptomatic carrier of Hemophilia A. CT scan was clear, but with blood in bladder. Can this cause problems?
It is more likely: Hemophilia mostly affects men. It is rare but not impossible for a female to have hemophilia. Hemophilia is a sex-linked recessive disorder: the trait is carried on the x chromosome which a female has two of and a male only has one. This means a female would have to inherit two copies of the hemophilia gene to have the disorder. A male only has to inherit one copy. ...Read more
Blood test: If suspected any doctor can order a blood test for hemophilia. There are two major types with deficiceny of different clotting factors, hemophilia a has deficincy of factor viii and hemophilia b of factor ix. Most hospital labs can do the testing on blood sample to make the diagnosis. ...Read more
How to help?: Children with hemophilia can lead long productive lives. It is essential that a pediatric hematologist is working closely with you and your child to develop a plan. Hemophilia can range from very mild to severe. If you have a more specific question, ask again. Otherwise, make sure you have a good relationship with a pediatric hematologist. They can point you toward good resources for help. ...Read more
