What is factor V deficiency?

Factor V deficiency is an inherited blood disorder that involves abnormal blood clotting (coagulation). This disorder is caused by the deficiency of a blood protein called factor V.[1] The reduced amount of factor V leads to episodes of abnormal bleeding that range from mild to severe.[1] Factor V deficiency is inherited in an autosomal recessive manner,[2] which means that both copies of the F5 gene in each cell have mutations.

What causes factor V deficiency?

Factor V deficiency is caused by mutations in the F5 gene that prevent the production of a functional factor V protein or decrease the amount of the protein in the bloodstream. Mutations are present in both copies of the F5 gene in each cell, which prevents blood from clotting normally.[3]

How is factor V deficiency treated?

Resources state that fresh plasma or fresh frozen plasma infusions will correct the deficiency temporarily and may be administered daily during a bleeding episode or after surgery.[1]  Individuals with factor V deficiency should discuss treatment options with their primary health care provider and a hematologist.
