Hemophilia is a problem with the blood in a person that causes them to bleed not any faster than normal, but they often bleed for a longer period. Their blood is missing the clotting factor (a protein in the bloodstream that works to control bleeding). Hemophilia is quite rare; roughly 1 in every 10,000 persons are born with it. Rarely, hemophilia can be an acquired disease which just means a person is not born with it, but will develop it during their lifetime. This rarity occurs when a person's immune system forms antibodies that attack the clotting factor in the blood. The entire antibody population fights against the blood to prevent the clotting factors from working properly.
Hemophilia A, the most occurring form of this disease,

Occasionally a baby is born with this disorder and no family history of it. When this happens, it could be caused by a hidden gene, which is when several generations of female carry it, and it has not affected any male members of the family or a spontaneous mutation. With each pregnancy, a woman who is a carrier has a 25% possibility of having a son born with hemophilia. Since the father's X chromosome is what determines if the unborn child will be a girl, all of the daughters born of a man with hemophilia will be carriers. None of his sons, which is determined by the father through his Y chromosome, will have hemophilia. Individuals who suffer from mild hemophilia may choose to use a non-blood product known as Desmopressin acetate (DDAVP) to help treat the small bleeds and/or scrapes. For deep cuts or internal bleeding, the treatment called DDAVP may not be enough and therefore, may need a much more complex treatment. The clotting factor must be replenished so the affected person can form a clot to stop the bleeding. Plasma is one of the ‘human blood products’ than is used for factor replacement. Another factor replacement option is using the recombinant factor, which is produced in a laboratory.
The second most common type of hemophilia is hemophilia B and is also known as factor IX deficiency, or the Christmas disease. It, like Hemophilia A, is an inherited disorder. It appears much less than Hemophilia A and occurs in “approximately 1 in 25,000 male births, and
Hemophilia is an X-linked recessive disease in which blood lacks blood-clotting proteins. Females have two X chromosomes, indicating that they are generally carriers and transmit the gene to their sons. People with mild hemophilia bleed after surgery, injury, or trauma. Severe hemophilia produces spontaneous internal bleeding in joints and muscles. Fortunately, medicines and lifestyle changes offers hemophiliacs fairly normal lives. Through learning about hemophilia, I became interested in genetic diseases and finding a cure for those
As the best of my knowledge I believe the two year old child is suffering from an inherited disorder called hemophilia. The Mayo Clinic describes hemophilia as a rare blood disorder that lacks sufficient blood clotting proteins. (Staff, B.M. ((n.d.)). Hemophilia. Retrieved September 27, 2016, from http://www.mayoclinic.org/disease-conditions/hemophilia/basics/treatment/con-20029824
The genetic disorder of Hemophilia is where the clotting factors of the blood are absent or deficient, causing it to be a dangerous disorder to the people who have it. This disorder is where the people who have it will bleed easily and accessibly. Different types of hemophilia are classified by different deficient clotting factors in the blood. Treatments for hemophilia are available, including transfusions of frozen
Haemophilia is a genetic disorder that is passed through generations on the x chromosomes, that affects the clotting factor in the blood and makes patients more prone to spontaneous and injury-resulted bleeding which is usually internal. According to the Haemophilia Foundation Australia (2015), there are over 3,000 cases of haemophilia in Australia, and more than half the cases are in males. The National Haemophilia Foundation (2013) website shows that cases of haemophilia go back to the 2n d century, where Jewish boys who have records of uncontrollable bleeding leading to death in their family do not have to undergo circumcision, also cases in 10th century Arabia show deaths of males after uncontrollable bleeding due to trauma. The first
Hemophilia, once called the royal disease is a problem with the clotting of blood. When a cut or bruise occurs it can bleed causing problems with people who suffer from hemophilia. Patients with hemophilia will continually bleed longer than a normal individual. This bleeding can lead to harmful levels of blood loss to internal bleeding. Hemophilia is very rare occurring once every five thousand people. Rare, however it is the most common x linked trait. When an injury occurs, blood cells called platelets plug the wound. Then fibrins seal it up. Hemophilia splits into two groups hemophilia A and hemophilia B. People who have hemophilia A have low levels of blood clotting factor 8. Hemophilia B patients have low levels of blood clotting factor
“Hemophilia (heem-o-FILL-ee-ah) is a rare bleeding disorder in which the blood doesn 't clot normally.” (NIH, 2013) Hemophilia is a chromosome – linked bleeding disorder caused by
Hemophilia is a hereditary and genetic mutation blood disease that does not have the ability to form a blood clot or coagulate from a small injury. The word hemophilia comes from two Greek words: haima - meaning blood and philia meaning to love. In order for the blood to clot properly, the plasma proteins also called factors need to be present in the blood. When the body forms antibodies to the clotting factors in the blood, it will stop the clotting factors from working. There are 13 types of clotting factors and they involve platelets to help the blood coagulate. Platelets also known as thrombocytes are small blood cells that form in your bone marrow to prevent blood loss by initiating a blood clot.
Hemophilia is a rare blood condition in which an individual’s blood cannot clot appropriately to stop bleeding. There are two types of Hemophilia, Hemophilia A and Hemophilia B. This paper will be focusing on Hemophilia A, also known as classic hemophilia. “Hemophilia A is a genetic disorder caused by a missing or defective factor VIII, a clotting protein” (National Hemophilia Foundation, n.d., para. 1). Clotting proteins work with cell fragments called platelets to stop bleeding. “When blood vessels are injured, clotting factors help platelets stick together to plug cuts and breaks on the vessels and stop bleeding (National Heart, Lung, and Blood Institute, 2013, para.
You mentioned hemophilia so I just wanted to explain what it was. Hemophilia is an inherited disease that affects the clotting process of your blood. Therefore, if you have hemophilia you do stand a chance of sever bleeding if you incur an injury or cut. There is a protein that is called clotting factor that a person might have little or none at all. It is a protein used for blood clotting that helps blood platelets stick together. (NIH
Haemophilia is an inherited blood clotting disorder where the blood doesn’t clot properly because there isn’t enough clotting factor VIII or IX in the blood of someone who is affected by haemophilia (ref). There are two types of haemophilia. The most common form, Haemophilia A, or Classic Haemophilia, affects people who are deficient in factor VIII and Haemophilia B, or Christmas Disease, affects people who are deficient in factor IX. Haemophilia can also be referred to as ‘the royal disease’ because it affected royal families in England, Germany, Russia and Spain in the 19th and 20th centuries. Queen Victoria from the English royal family is believed to have carried the altered gene of haemophilia having a factor XI deficiency. In Australia there are approximately 3000 people affect by haemophilia and majority of them are males, with severe haemophilia extremely rare in females, but some females do have lower factor levels and bleeding symptoms. Abnormal bleedings had first been recorded hundreds of years ago, but wasn’t announced publicly until 1803 when a physician from Philadelphia, John Conrad Otto, published an article about a hemorrhagic bleeding disorder that affect mainly males.
Hemophilia is an inherited bleeding disorder that is passed from mother to son. This affliction is passed in such a way due to the fact that the gene that is responsible for hemophilia is carried on the X chromosome that the child receives from his mother. For someone to be afflicted by hemophilia means that their blood has a difficult time clotting. There people do not bleed any faster than the average person, they simply cannot stop bleeding once they start bleeding. As of this current moment, there are no known cures for hemophilia, but there are many treatments that are highly effective in helping to treat many of the issues associated with the bleeding disorder. (citation)
In general, such carrier females do not bleed excessively, as their other X chromosome, with a gene for normal FVIII (or FIX) production, results in intermediate levels of FVIII (or FIX). However, carrier females have a fifty-fifty chance of passing their X chromosome that bears the hemophilia gene to each child they might have. A son would have an equal chance of being normal or having hemophilia. A girl would have an equal chance of being normal or being a carrier, like her
Blood is essential to human life. It carries oxygen, nutrients and hormones all through your body with a strong pump from the heart. Steven’s inability to stop bleeding could be detrimental to his health. There are many bleeding disorders existing today but the main, most common ones are limited to hemophilia A, hemophilia B, and von Willebrand disease. Von Willebrand disease is carried on chromosome 12 and occurs equally in men and women, unlike hemophilia which is an x linked disorder typically affecting males more often. There are many other rare forms of hemophilia with deficiencies in clotting factor 1, 2, 5, 7, 10, 11, 12, and 13 but type A and B specifically involve defective genes relating to factor 8 and 9, respectively. Through the
Hemophilia is the oldest known hereditary bleeding disorder. There are two types of hemophilia, A and B (Christmas Disease). Low levels or complete absence of a blood protein essential for clotting causes both. Patients with hemophilia A lack the blood clotting protein, factor VIII, and those with hemophilia B lack factor IX. A person with severe hemophilia has less than 1% of the normal amount of a clotting factor - either Factor VIII (8) or Factor IX (9). People without hemophilia have between 50-150% of the normal level of factor VIII or IX. There are about 20,000 hemophilia patients in the United States. Each year, about 400 babies are born with this disorder. Approximately 85% have hemophilia A and the remainder has hemophilia B.
Mutations in this factor lead to Hemophilia B2. Two vectors—AAV-CMV-F.IX and AAV-EIFα-F.IX—were inserted into the muscle, each having a similar role2. Both vectors were responsible for inducing the activity of the coagulation factor IXa, which is absent in patients exhibiting Hemophilia B, and plays a crucial role in blood clotting2. The results of this study showed that while the two vectors played similar roles, there were important distinctions between the two that determined the AAV-CMV-F.IX vector was more useful for XI factor deficiency2. A potential downfall of using AAV was the issue of tumors being caused in animals due to the vectors2. More studies will have to be completed to address this issue
