Transcript of Haemophilia

Haemophilia By: Tyler Choi What is haemophilia? Haemophilia is a recessive disorder which damages the x chromosome (which includes clotting factors) so it can't develop red blood clots when a blood vessel is damaged. There are 3 types of haemophilia, A to C, A being unsevere, to C being lethal.
X chromosomes are one of 2 sex determining chromosomes.
Chromosomes are organized colonies of DNA and protein in cells. Normal situation When most people get a cut, bleeding occurs and then stops because blood clots are formed from the clotting factors of the X chromosome to prevent the blood from flowing out. Coagulation Symptoms of Haemophilia In most average cases of haemophilia, some of the symptoms are
Long nosebleeds
Excessive bleeding from biting on tongue, lip, and after surgery or tooth extraction
Blood in urine
Bleeding in joints and muscle
swelling and pain in joints and muscle
Spontaneous bleeding
digestive problems
Large bruises
Spontaneous bleeding varies depending on the severity of the disease. Causes of the disease Man have XY chromosomes, while females have XX chromsomes. It is more likely for men to have this disease, since they only have one X chromosome. If males have haemophilia, then their daughters will be carriers of the disease. If a female carrier has children, then the son will have haemophilia, and the female will be a carrier. Haemophilia is genetically acquired. Organs and systems affected by the disease From the symptoms, Haemophilia will affect mostly the nervous sytem
urinary system
skeletal system and;
muscular system
Can also affect most parts of the body, such as the airways, because haemophilia also cause internal bleeding. Prevention from the disease There is no prevention for the disease because it is genetic.
Aspirin, Painkillers, or ice packs can help ease the pain. Treatment for the disease

-Injecting Blood clotting factors

This treatment is expensive Population affected by the disease About 18000 people have haemophilia in the U.S. Haemophilia A 70%
Haemophilia B 20%
Haemophilia C 10% Interesting facts about the disease/Did you know? known as the "Royal Disease"
Haemophilia B is called "Christmas Disease"
Can be spelled 2 ways "Hemophilia", "Haemophilia".
