I am a CF carrier, as is my DD and GS. None of us has full-blown CF symptoms.
However......I have always had IBS and lengthy bad colds with chestiness (I am just embarking on my second of the year); my DD has lived all her life with over-production of mucus and sometimes is continuously on beconase (I have know her get through a whole box of tissues during a night - at a time when she has not got a cold); and her wee son just coughs and coughs. He was the one who alerted us to the problem because he was diagnosed with CF to begin with, then that was changed to carrier status. They said it was unusual for a baby with carrier status to show up as a sufferer on the normal screening test, which is what he did.
Interestingly there is a body of research that is beginning to show that CF carriers are often subject to symptoms - basically to a milder version of the disease. The reasons seem to be that in symptomatic carriers another genetic error is interacting with the faulty carried gene.
Anyone else in this situation or know anything about it? I am not an expert on genetics but for obvious reasons have an interest in this.
