Factor V(5) Deficiency
Factor V (5) is one of the clotting factor proteins that are needed to help the body form a blood clot to stop bleeding. People diagnosed with Factor V (5) Deficiency do not have enough factor V (5) clotting protein in the blood. Not having enough of any of these clotting proteins can delay the time it takes to make a blood clot and for this blood clot to be weak, causing bleeding to last longer or to stop and then start back up again.
Factor V (5) Deficiency is a rare, inherited bleeding disorder. One or both parents can pass the abnormal gene for Factor V (5) Deficiency to their child. If one parent passes the gene to their child, it is called heterozygous and usually symptoms are minimal. If both parents pass the affected gene to their child, it is called homozygous and makes the risk for much bleeding higher because both genes are affected.
