A member asked:
Do you and your partner have to carry the same mutation to have a child with cf ?

Not exactly: The mother and father can have different abnormalities in the gene. If the baby inherits two defective copies of the gene s/he is likely to get cf, even though the abnormalities are not exactly the same in parents.

80% Delta 509: I believe there are at least 2 dozen variations of the CF gene that can pair up to produce the disorder.Most kids will have 2 of the delta 509 variation, but one of these along with another variant will still produce CF. This is responsible for some of the variation in presentation and symptom expression at different ages.
