  • I was recently diagnosed with factor V Leiden. It was found when I needed surgery on my right ankle, which just broke without injury. I was on Coumadin, a blood thinner. Then two months after surgery, my left ankle broke in the same exact spot again just from being on crutches. The same bone broke at the exact spot on both ankles, so I started asking questions. My orthopedic surgeon said because of the factor V Leiden I was getting blood clots in the capillaries going to that section of my bone. The effect was of course bone death and breakage. I would like to know if my doctor's claims could be plausible. Click here for answer

  • My grandmother on my dad's side has two copies of the factor V Leiden gene mutation. I have one copy. Do I need to go and see a hematologist to get on blood thinners, or is there really nothing that they would do since I only have the one copy? Also, if I have one copy does that mean that my father has two copies of it or could he possibly have only the one copy as well? Click here for answer

  • My husband has factor V Leiden. How could he have this when nobody else in his family has it including his parents? Is this disorder always passed down or can it skip a generation? What is the chance that our kids will have it? Click here for answer
