Can a child have CF if only one parent is a carrier?

If only one parent is a carrier of a defective CF gene, the child will not have CF. But there is a 50% (1-in-2) chance that the child will be a CF carrier. If both parents are carriers, there is a 25% (1-in-4) chance that the child will have CF, and a 50% chance that the child will be a carrier.

Can a black person have cystic fibrosis?

Can you have CF and not know?

While cystic fibrosis is usually diagnosed in childhood, adults with no symptoms (or mild symptoms) during their youth can still be found to have the disease.

How is CF inherited?

Every person inherits two CFTR genes, one gene from each parent. Children who inherit a CFTR gene with a mutation from both parents will have cystic fibrosis. When a mutated CFTR gene is inherited from only one parent and a normal CFTR gene is inherited from the other, the person will be a cystic fibrosis carrier.

Can a child have cystic fibrosis if neither parent has it?

Can my children have CF even if it is not in my family? Yes. In fact, most couples who have a child with CF have no family history of cystic fibrosis and are surprised to learn that they carry a mutation in the CFTR gene, which causes the condition.

Can you get cystic fibrosis later in life?

As with other genetic conditions, cystic fibrosis will have been present since birth, even if it is diagnosed later in life. One in 25 people carry the faulty gene that causes cystic fibrosis. To have cystic fibrosis, both parents must be carriers of the faulty cystic fibrosis gene.

How does cystic fibrosis affect you sexually?
