Factor VII deficiency

Disease Overview

Factor VII deficiency is a rare bleeding disorder. The age of onset and severity varies from person to person. While severe cases may become apparent in infancy, very mild cases may never cause any bleeding problems. Signs and symptoms may include nosebleeds; easy bruising; bleeding gums; excessive or prolonged bleeding after injury or surgery; and heavy or prolonged menstrual bleeding in women. Some people with factor VII deficiency may have bleeding in the joints or blood in the urine. In very severe cases, factor VII deficiency can be life-threatening, causing bleeding inside the skull or digestive tract.[14675]

Factor VII deficiency may be inherited or acquired. The inherited from is caused by mutations in the F7 gene and inheritance is autosomal recessive. The acquired form is not inherited and may be caused by liver disease, blood cell disorders, certain drugs, or vitamin K deficiency.[14675] Treatment for bleeding may include intravenous infusions of normal plasma, concentrated factor VII, or genetically-made (recombinant) factor VII. Those with acquired factor VII deficiency due to vitamin K deficiency may take vitamin K by mouth, injection, or infusion.[14676]
