More than 1,125,000 men around the world have the inherited bleeding disorder of hemophilia, and 418,000 of those have a severe version of the mostly undiagnosed disease, says a new study led by McMaster University researchers.
This is three times what was previously known. Only 400,000 people globally were estimated to have the disorder which is caused by a defect in the F8 or F9 gene which encodes instructions for making the factor proteins that helps blood clot. For those with hemophilia, lack of treatment leads to chronic and disabling joint disease, while bleeding into organs and brain hemorrhages can lead to disability and death.
