Nine out of ten children born with cystic fibrosis are born into families with no known family history of the condition. To have a child with cystic fibrosis, both parents must be a carrier of the gene change that causes cystic fibrosis.
Cystic fibrosis carrier screening services are available to help you and your partner find out whether you are among the one million Australians who carry the gene change.
If both parents are carriers of the cystic fibrosis gene change, then with each pregnancy there is a 25% risk of that child having cystic fibrosis. Being a cystic fibrosis carrier does not mean you have cystic fibrosis and carriers usually display no symptoms of cystic fibrosis.
Carrier screening is as simple as having a blood test or a saliva swab. Other family members can choose to be tested so they are aware of their cystic fibrosis carrier status if they are planning to have children.
To find out more about carrier screening, contact your cystic fibrosis clinician.
