</a>Your husband's mutation if I'm reading your message correctly that he has G542X is not rare. In fact I believe it is the 2nd most common mutation. It is a class 1 mutation. Yours I'm not seeing much on. There is no clear cut information about clinical outcome for mutation pairing becuase mutations alone do not dictate outcome. Enviro, diet, compliance, modifier genes, etc. come into play. They are doing studies on twins to learn more about this large unknown territory of cf. What you can do is look at each mutation seperately regarding their clinical outcome results. The person generally presents more characteristically of their milder mutation. I hope this makes sense.
So when in your pregnancy did they find your mutation? Did you write an intro post somewhere? I'm curious to hear more about why they ran all the tests ....maybe it's part of IUI with sperm washing?? but then wouldn't they have found your carrier status before you got prego? I'm guessing they found your mutation as part of your first blood workup which would make sense if you had your husbands mut but I didn't think they would find 2789+G>A in a general screening like that. I'm not buying that its just that you have "really good Dr's." Could it be that you have the mutations reversed?
