Hemophilia
Hemophilia is a hereditary bleeding disorder where essential factors needed to make blood clot are missing. The abnormal hemophilia gene is found on the X sex chromosome. This abnormal gene is there in place of the factor VIII gene. People without the factor VIII gene have hemophilia A. Also, the hemophilia gene can be in place of the factor IX gene as well. People without the factor IX gene have hemophilia B. Hemophilia B is also known as the Christmas disease. (Marshall Cavendish Limited)When these factors are missing the body cannot make fibrinogen, the substance that makes the fibers that make blood clot. 80% of hemophiliacs have the hemophilia A disease, while only 20% have the hemophilia B disease. 80% of all cases of hemophilia have an identifiable family history. Hemophilia may also come from the spontaneous mutation of genes. (Microsoft Encarta online Encyclopedia 2000) Hemophilia is the oldest known hereditary bleeding disorder. There are around twenty thousand patients in the US with hemophilia. Four hundred babies are born each year with hemophilia. 70% of hemophilia A patients have less than 1% of the normal person's clotting factor.

In conclusion the disease Hemophilia is a very sever disease that keeps a person's blood from clotting because of the absence of certain factors. That even though Hemophilia is a sever disease people that have it can lead normal lives, if they are careful. Through modern medicine people have a better chance of living to adulthood and have almost perfected treatment for cuts that Hemophiliacs experience and will not get hemophilia. But, they will become carriers of the disease. And female carriers are usually symptom free. In some rare cases if both of the parents have the hemophilia gene, the female will get hemophilia. While if a male gets an X chromosome with the hemophilia gene he will have the disease. This is because his only other chromosome is the Y chromosome. One out of every ten thousand boys is born with the diseases. Hemophilia affects all races and economic groups equally. (Macmillan Health Encyclopedia) chromosome. Because of this, if a female gets an X chromosome with the hemophilia gene, they still have the other X chromosome with the factor VIII and XI genes on them
