If a person inherits the changed gene from
only one parent, he or she will not get cystic fibrosis but will be a
carrier of the disease. Carriers may pass the gene defect on to their children.
If you are planning a
pregnancy and you are white, talk to your doctor about having a
genetic test to find out your chances of having a
child with cystic fibrosis. The disease is much more common in white people
than in people of other races.
