Defects In The Factor V Gene
701 wordsThe genetic disorder which I have chosen as the subject of my report is hemophilia. There are two types of hemophilia, hemophilia-A and hemophilia-B. The clinical symptoms of both are very similar so for the purposes of this paper I have chosen to concentrate on hemophilia-A. Hemophilia-A is an X linked bleeding disorder resulting from a defect in a protein known as coagulation factor V. Since the disorder is X linked it is expressed mainly in males, who must have mothers who are carriers. Femal...
Hemophilia And Female Carriers
369 wordsHemophilia Tim Pois al Biology-2nd period Hemophilia is a genetic blood disease, which is characterized by the inability of blood to clot, or coagulate even from minor injuries. This disease is caused by an insufficiency of certain blood proteins, called factors, that participate in blood clotting and often by sudden gene mutation. Therefore, with the absence of factors, the blood clotting process is prolonged. There are different types of hemophilia, hemophilia A and hemophilia B for example. H...
Carrier Of The Hemophilia Gene
1,050 wordsHemophilia Hemophilia is the oldest know, lifelong bleeding disorder ("Hemophilia"2004). It is named for two inherited diseases in which the blood does not clot normally. Several different plasma proteins must be present for blood to clot property. If one of the plasma proteins is missing, or present at low levels, blood clots very slowly ("Hemophilia" The Marshall Cavendish). The two most common types of hemophilia are: Hemophilia A or Factor V (8) deficiency and Hemophilia B of Factor IX (9) d...

More Severe Cases Of Hemophilia
1,435 wordsHemophilia By Chelsea Stevenson Biology 30 Mr Friesen May 18, 2005 Hemophilia is a hereditary bleeding disorder. (6) (7) In most people when they get a cut the platelets plug the hole and release chemicals which attract proteins and activate proteins found in the blood that are known as clotting factors. (6) The proteins mix with the platelets and create fibres; the fibres then make the clot stronger and stop the bleeding. (6) Hemophilia is a deficiency in one of the 12 blood clotting factors. (...
More Factor V Replacement Therapy
1,036 words... As more blood leaks into the joint it feels warmer than the opposite one and the swelling feels 'spongy'. Later the person holds the limb in a bent or 'flexed' position to ease pain. Flexion increases the space in the joint, making more room for further bleeding to occur. If untreated, the bleeding continues until the area feels hot and rock hard. Usually there is no bruising associated with a joint bleed, and since the bleeding occurs in an enclosed space (the joint capsule) and has nowhere...
Normal Clotting Of Blood
1,601 wordsHemophilia Can you imagine being born not able to play sports Or can you imagine what it would be like if you had to be injected with blood regularly just to stay alive For more than 15,000 Americans, this way of life is a reality. Hemophilia is an inherited disease in which one or more blood-clotting proteins called antihemophilic globulin, or factor V are defective. This is what these people are suffering from. In fact, out of every 10,000 baby boys born, at least 1 of them suffers from hemoph...
Blood To The Brain
580 wordsStroke When a family member has a stroke, the family could also be highly affected. The person may have slurred speech, facial weakness, loss of bladder control, difficulty in breathing and swallowing, and paralysis or weakness, particularly on one side of the body. A stroke is also referred to as cerebral apoplexy and cerebrovascular accident (CVA). It is a cardiovascular disease that affects the blood vessels supplying blood to the brain. It is also called a brain attack. A stroke occurs when ...
Clotting Factor V
1,033 wordsIn the human body, each cell contains 23 pairs of chromosomes, one of each pair inherited through the egg from the mother and the other from the sperm of the father. Of these chromosomes, those that determine sex are X and Y. Females have XX and males have XY. In addition to information concerning sex, the X chromosomes carry determinants for a number of other features of the body, including the levels of factor V and lX. If the genetic information determining factors V and lX is defective, hemo...
