Is factor V Leiden the same as thrombophilia?

Factor V Leiden thrombophilia is an inherited disorder of blood clotting . Factor V Leiden is the name of a specific gene mutation that results in thrombophilia, which is an increased tendency to form abnormal blood clots that can block blood vessels.

What does heterozygous factor V Leiden mean?

Heterozygous means that the 2 copies of a gene are different. In your case, one of your Factor V gene codes is for normal clotting Factor V and the other Factor V gene code is for Factor V Leiden. There is more risk of a blood clot if both gene codes are for Factor V Leiden (ie in the homozygous state).

What are the two types of factor V Leiden?

Having 1 Factor V Leiden gene (heterozygous type) slightly increases the chance of developing a blood clot. Having 2 Factor V Leiden genes (homozygous type) makes the risk much greater. Having Factor V Leiden does not appear to increase the chances of developing a heart attack or stroke.

Is Factor V Leiden thrombophilia dominant or recessive?

Genetic counseling: Factor V Leiden thrombophilia (i.e., predisposition to the development of venous thrombosis) is inherited in an autosomal dominant manner. Homozygosity for the Leiden variant (and a much greater risk for venous thrombosis) are inherited in an autosomal recessive manner.

What causes Factor V Leiden thrombophilia?

Cause. Factor V Leiden thrombophilia is caused by a specific mutation in the F5 or Factor V gene . F5 plays a critical role in the formation of blood clots in response to injury.

What is thrombophilia in pregnancy?

Thrombophilia is a group of genetical disorders that cause blood to clot abnormally. Thrombophilia is linked to recurrent pregnancy loss, foetal growth restriction, late miscarriages, stillbirth and preeclampsia. Clinicians usually apply the term thrombophilia only to patients with atypical thrombosis.

How is Factor V Leiden thrombophilia inherited?

Can Factor V Leiden cause headaches?

It has been reported that in a group of patients with cerebral ischemia and the Leiden mutation of factor V, 67% had classical migraine.
