Can you die from hemophilia?
Yes, you can die from hemophilia. The condition prevents clotting of the blood, so you could bleed to death.
Why is Hemophilia a very serious disease?
Hemophilia is a serious disease because you don't have the right proteins to clot up your blood( called clotting factors) If you cut yourself and you have hemophilia you could bleed to death if you don;t go to the doctor right away.
How does hemophilia progress?
Hemophilia is a recessive allele condition. Men can get hemophilia alot easier than women as the allele is found on the XY Chomosome pair. With men. they do not have the extra "tail" on the Y chromosome compared to the XX with a female. If the person has the recessive allele on the X chromosome and this person is male, they will be a hemophiliac as they do not have a 'pair' allele which could be dominant to stop the condition expressing itself. On a female, if there is a recessive (hemophilia) allele on one of the X chromosomes but on the other is a Dominant (normal) allele then she will be a carrier of the faulty gene but will not suffer from the condition herself. If the female have a recessive (faulty) gene on each of the XX chromosomes, then she will be a sufferer of the disease.

In a family with parents who do not have hemophilia one son has hemophilia. Who was the carrier of the gene for hemophilia?
First of all, Spontaneous mutations account for 1/3 of the cases of genetic hemophilia. This means that 1 out of 3 people born with hemophilia have no family history of the trait prior to that person. In the scenario you are describing, you are assuming that there was a carrier when in fact, there is a good chance that there was not. There is also a chance that the child born with hemophilia received the mutation from his mother. Frequently women will have the mutation on one X chromosome but not their second. Depending od the individual case, the mother could carry the gene but not be symptomatic. It is impossible for the son to have received the gene from his father. Since in order for a boy to actually be a boy, he must receive his father's Y chromosome and not his X chromosome, a son cannot receive the affected X chromosome from his father. Also, in order for a father to pass the trait on through daughters, the father himself would be a hemophiliac.

The disease that results from a failure to form blood clotting factor VIII is?
Hemophilia i think... but i could be wrong
A woman is a carrier for hemophilia what are the chances for sons with hemophilia if the father does not have hemophilia?
Since the gene for Hemophilia is carried on the X chromosome and males pass only their Y chromosome onto their sons, no their sons should not have hemophilia. Of course all daughters of a male with hemophilia will be carriers of the mutation since they with receive his X chromosome, not the Y.
What does hemophilia look like?
Hemophilia is invisible except when the afflicted person is bleeding, then it is visible in terms of prolonged bleeding, beyond the point when a normal person would have stopped bleeding.
Could a Girl have hemophillia?
Yes. Hemophilia is sex-linked, and is much more common in males than in females, but it is not impossible for a girl to have hemophilia.
Why is Hemophilia a very serious disease?
Hemophilia is a serious disease because you don't have the right proteins to clot up your blood( called clotting factors) If you cut yourself and you have hemophilia you could bleed to death if you don;t go to the doctor right away.
What lifetime changes must be made when you have hemophilia?
Avoid situations where you could cut yourself.

What does it mean when a child 's blood does not clot right?
It could mean that the child has Hemophilia, a rare disorder where blood does not clot fast and can bleed for serveral hours after a cut or injury where blood is lost (this is including internal injuries.) If you were bleeding internally you most likely could not determine it, and where some people's may be able to heal, a person with Hemophilia could not. If you suspect a child you know has Hemophilia, consult a doctor IMMEADIATLY.
Who was the Russian monk who reputedly could treat the Czarevich's hemophilia?
Grigori Rasputin was that Russian monk.
Could hemophilia disorder have been prevented?
The simple answer is - you can't ! Hemophilia is a genetic medical condition - not a communicable disease. A person is born with the disease. You can't 'catch' it from being in contact with someone - nor is it spread by the person touching surfaces etc. It is treatable - but incurable. A person with Hemophilia has it all their life.
When did Abraham Lincoln get hemophilia?
It is actually not possible to 'get' hemophilia. Hemophilia is passed on from the mother (the carrier) to the son, not the daughter as it is rare for a girl. A boy has two chromosomes, an X and a Y, and girl has two X's. Hemophilia is inherited through the X chromosome, so a girl can carry hemophilia, but unless she inherits hemophilia on both of her chromosomes, she can't have the disease. REGARDING YOUR QUESTION, It is actually not confirmed whether Lincoln had hemophilia, people suspected some sort of genetic disorder, there were two suspected and hemophilia was one. People didn't know very much of the disease when Abraham was president. In fact is wasn't a named disease until 1828, and then hemophiliacs often didn't live pass the age of thirteen. With not much doctors could do to stop bleeding, and considering the age of Abraham its unlikely he had hemophilia.
