THE TEACHING CONNECTION
Factor V Leiden concerns clot regulation
Factor V Leiden concerns clot regulation
F5 encodes coagulation factor V. The well-characterized Factor V Leiden variant, rs6025, can make factor V less responsive to an anticoagulant control mechanism, increasing susceptibility to venous clots. It does not mean the body cannot make factor V.
Putting the pieces together
Dr. Purser highlights this pathway when discussing clotting history and oral estrogen. The clinical importance depends on the confirmed result, whether one or two copies are present, previous clots and other risk factors. Discuss hormone and medication choices with the prescribing clinician rather than starting aspirin or an anticoagulant from an encyclopedia page.
A question to bring to your visit
