How can two parents without cystic fibrosis have a child with this disease?

A person must inherit 2 CF genes to have CF disease. When your child was conceived, he or she received a CF gene from both you and your partner. A child can inherit CF only if both parents carry a CF gene (that is, each parent either has CF or is a carrier) and both parents pass the CF gene on to their child.

Is it possible for two parents who do not have cystic fibrosis to give birth to a child with cystic fibrosis?

A person with one non-functional copy of the gene is a carrier. Carriers for CF have no symptoms, but can pass the non-functioning gene on to their children. An individual must inherit two non-functioning CF genes – one from each parent – to have CF.

Why is cystic fibrosis autosomal recessive?

CF is inherited in an autosomal recessive manner. This means that to have CF, a person must have a mutation in both copies of the CFTR gene in each cell . People with CF inherit one mutated copy of the gene from each parent, who is referred to as a carrier .

Do lung transplants cure CF?

Transplantation is an important treatment option for damaged CF lungs, but unfortunately it is not a cure for CF. The lungs that are transplanted into the recipient’s body do not have cystic fibrosis because they have the DNA of the person who donated them, and not the DNA that the transplant recipient was born with.

Can you live a full life after a lung transplant?
