Hemophilia is passed down from mother to son. It is extremely
rare for a woman to have hemophilia. It is necessary, though, for
a woman to be a carrier of the disorder for her son to acquire this
disorder. Females have two X chromosomes whereas males only
have one. When a boy is born, he takes one X chromosome from
his mother and one Y chromosome from his father. Therefore, he
can only get hemophilia through his mother.
Example One:
Mother(Carrier)+Father(Non-Affected)=50% chance of their son
acquiring the disorder and 50% chance of their daughter being a
carrier.
Example Two:
Mother(Non-Affected)+Father(Hemophiliac)=All sons will be
non-affected and all daughters will be carriers.
No, Hemophilia is a genetic disease. A person is born with it.
Hemophilia is caused by a deficiency of clotting factor VIII (hemophilia A) or clotting factor IX (hemophilia B).
There are no hard answers to this, it depends strictly on luck. The statistics are though not very good for their children. Statisically the couple have a chance of having a normal son, a daughter that is a carrier for hemophilia, a daughter with hemophilia and a son with hemophia.
50 million ppl have hemophilia
Her father has to have hemophilia as well, and the mother is a carrier or also has hemophilia. So if we pretend that the hemophilia gene is "x", you need to have "xx" to have hemophilia. The father must have the genotype "Yx" and the mother has the have "Xx" or "xx".
No, Hemophilia is a genetic disease. A person is born with it.
You have to be born with hemophilia, it is not something people can "catch".
You can be born with it.
Approximately 1 in 5000 males born have hemophilia. Approximately 1 in 10,000 children have hemophilia.
Hemophilia is not contagious by any means, however it can be passed from parent to offspring in the way of genetics.
It is possible but extremely rare.
Hemophilia is one disease in which blood does not clot normally. von Willebrand's Disease
Haemophilia is a congenital disorder, those that have it were born with it and it manifests early in life.
There is no chance that the child will have hemophilia even if the spouse has hemophilia. Any girls the couple has will be carriers if the spouse has hemophilia.
50%
The gene that causes hemophilia is located on the X chromosome. A woman who gives birth to a child with hemophilia often has other male relatives who have hemophilia. Sometimes, a baby will be born with hemophilia when there is no known family history. This means the gene can be"hidden"( or passed down through several generations of female carriers without affecting any male members of the family) or the change in the X chromosome is new (a spontaneous mutation).
No, Hemophilia does not discriminate on age, race or religion. Hemophilia is a genetic disorder (with the exception of acquired hemophilia) and therefore an individual has hemophilia from the the time they are born until they die. There is one very rare form of genetic hemophilia where the individual "outgrows" the disorder. In fact, the hormonal changes that take place during puberty increase the production of the clotting proteins to a point above the 50% cut off for being considered as having hemophilia. the genetics however, remain the same.
