This is how the story played out for us.....I went to the doctor and when i was filling out the health history, i put down that my boyfriend HAD cf. I dont know what they did when he was younger, but the's always thought that he had a very mild case. I wasn't too worried, since i didn't know anything about cf at the time, and because he is literally the healthest person i have ever met...not a sniffle the entire time we've been together. When i went to speak with my doctor, and he told me that men with cf tend not to be able to have children naturally, i was even less concerned. They ended up testing me just to make sure, and i came back as a carrier. When we went in for the ultrasound however, the was a bit of an issue with the nucal fold, i think it's called, which is an indicator of down's syndrome. We decided to have an amino based on that, and we brought up the topic of cf to that doctor. My boyfriend hasn't had genetic testing for cf, and right now he doesn't have insurance, so they told us that the test wouldn't be 100%, but it could give us an idea. So we sent it out to the lab, and about a week later the genetic counselor called and said that the baby has 2 mutations both for the delta f508, so it turns out that my boyfriend is a carrier after all. So now i just wonder what that particular mutation means, and if i should be any more worried that i already am?
