I deleted your other thread, as it was the same question really. Which breaks healingwell's rules and guidelines on postings.
If you need to pose any more questions about the double mutation, please post in this thread.
Here is your question from the other thread, so others can see it:-
Hello everyone! I was just wondering if having a double mutation with CF is rare or if it is fairly commom? I'm not sure. If there is anyone who knows anything about
it, please let me know what you know. Thank you very much. I hope everyone has a great day! Makxis (mother of 2 little girls, one with CF and one without CF.)
Hope you're having a good day
