Gene mutation?

I just posted my 27 week pregnancy update on my blog. I found out today I have a gene mutation that is a known trigger for pre-eclampsia, which I've had twice. I've got MTHFR a1298c, an inherited blood clotting disorder. Besides triggering PE, it raises the risk of blood clots, stroke, and heart attack, although those risks can be easily managed now that I know I have it. I wondered if anyone on this side of the family has been diagnosed with this.
