The primary cause of the defective hemostasis in hemophilia is the lack of thromboplastinogen in the blood. This anomaly is congenital and hereditary. The mechanism whereby the concentration of thromboplastinogen is depressed in the blood is not known and no satisfactory explanation can be given why...
In hemophilia, one of the clotting factor proteins normally needed for the blood to clot does not work properly, either because the protein itself is abnormal, or because too little or none of it is being produced.In the vast majority of cases, hemophilia is caused by mutations in a gene ...
The Hardy-Weinberg law indicates that the frequencies of genes in a large population will stay constant from one generation to the next provided that there is no migration into or out of the population, no natural selection, no mutation, and no genetic drift. This, then, is a theoretical ...

Hemophilia is usually inherited. This means a gene is passed from parent to child. Your risk for hemophilia is higher if you are male. If you are female, you may carry and pass the gene but not have hemophilia.Blood tests are used to check the type and amount of clotting factor you ...
The use of gene therapy to replace the defective genes is currently under study. Blood transfusions may be required in case of significant blood loss. SLIDESHOW The 14 Most Common Causes of Fatigue See Slideshow What are the signs and symptoms of hemophilia? The symptoms of hemophilia may ...
The risk for hemophilia is higher if your child is male. Your female child may have the gene but not have hemophilia.Blood tests are used to check the type and amount of clotting factor your child has. Your child's clotting factors and platelets will be tested for how well they work. ...
But even if a woman (XX) has one X chromosome with the hemophilia gene, the other X chromosome is probably normal, and her body will produce enough factor VIII or IX to ensure that the blood will clot. The Y chromosome, however, has no part in the production of blood-clotting factors...
For example, gene therapy delivered to the liver has the potential to treat metabolic diseases like hemophilia, whereas gene therapy designed to reach the central nervous system (brain and spinal cord) may primarily impact symptoms of diseases that affect the brain and cognition. Next, the NAV ...
