Shaun Zandnia haemophilia a) The main symptom of haemophilia is expel. Mild cases may go unnoticed until later in life, when they occur during operation or after trauma. In more severe cases, undecomposed bleeding may occur without any cause. Internal bleeding may occur anywhere. Bleeding into joints is common. b) (See table below for chart) bleeders disease A (clotting component VIII deficiency) is the well-nigh common comprise of the dis guild, occurring at round 1 in 5,00010,000 male births. hemophilia B (factor IX deficiency) occurs at active 1 in about 20,00034,000 male births. It is very unlikely for a feminine to be affected c) Current research beas and intercessions under outline include: Recombinant factor VIII factortically engineered to avoid risks of disease transmitting by infusion and also gene therapy. d) Direct transition Testing For Hemophilia A and B, it is possible to go out for mutations inside the gene. This approach is called look at DNA interrogatory and is the most accurate method for identifying common carriers. A blood example from the male family member with hemophilia is analyse first. In about 98% of cases, a mutation send word be identified. Next, a blood sample from the woman desiring carrier exam is obtained, and her DNA is checked for the specific mutation.

Such interrogation is performed at specialized laboratories. Results are generally available in some(prenominal) weeks.  Linkage (Indirect) Testing In some cases of Hemophilia A and Hemophilia B, a mutation cannot be identified. However, it may be possible to use indirect or linkage tests to look on the gene carrier status of females by track the gene in the family. Blood sam! ples are obtained from the male with hemophilia and early(a) family members. Patterns of linked DNA in the person with hemophilia are compared to the DNA in family members to check for the same pattern. Linkage interrogation is not as accurate as direct test and does not provide information for all families. e) The main intercession for hemophilia is...If you want to get a full essay, grade it on our website: OrderEssay.net
