Hi, perhaps I can be of some help to you.
I would like to see if you can be a bit more specific here. Perhaps, if a couple was thinking about having a child and possibly having CF? Let me answer this one.
There is a 1 in 4 chance that both parents can concieve a child or children (in my case twins) having cystic fibroisis. In my case, I have 3 children. My first girl born did not have CF. My twins born 10 yrs later did have CF. I am a carrier, my husband is a carrier, my daughter is a carrier, her daughter is a carrier. But does this mean that everyone who is a carrier will concieve with their spouse a CF child? the answer would be no.
I hope this helps some and if you need further assistance, I'd be happy to help.
