Hemophilia B results from too little plasma protein IX which helps blood clot. The levels of hemophilia are mild 5%-25% of the normal factor VIII level, moderate 1%-5% of the normal factor VIII level, severe 1% of the normal factor VIII level. People with hemophilia A have moderate to severe symptoms but unlike hemophilia A hemophilia B cab be either mild, moderate or severe, the greater the deficiency the more severe the symptoms.
