What type of mutations that cause hemophilia a?

Gene on X-chromosome: Hemophilia a is a hereditary bleeding disorder where there is a deficiency in clotting factor viii (factor viii is needed for blood clotting). It is inherited on the x-chromosome (sex-linked). Men only have 1 "x", so if their "x" is mutated, they will have the disease. Women have 2 "x's", so they can have 1 mutated "x" and 1 normal "x", and be a carrier of the disease, with mild or no symptoms. ...Read more

The bleeding stops itself by having a limited space to expand.It can time for the blood to break down and be absorbed.It will sometimes form a calcium deposit. ...Read more
