Can a baby have cystic fibrosis if neither parent is a carrier?
Inherited, or genetic, diseases like cystic fibrosis (CF) are passed from parents to their children. This occurs even when neither parent has the disease. For a child to inherit CF, both parents must have an altered gene that causes CF; that is, both parents must be carriers of an altered CF gene.

Which parent carries the gene for cystic fibrosis?
Cystic fibrosis (CF) is a genetic disease. This means that it is inherited. A child will be born with CF only if they inherit one CF gene from each parent. A person who has only one CF gene is called a CF carrier.

Can baby have CF if mom is not a carrier?
If one parent is a CF carrier, and the other parent is not a carrier, then for each pregnancy, there is a 50% chance of having a child that is a carrier for CF and a 50% chance of having a child that is not a carrier for CF. Your baby does not have cystic fibrosis.
