About Cystic Fibrosis
Cystic fibrosis (CF) is the most common, fatal genetic disease affecting young Canadians. CF is a multi-organ disease affecting primarily the lungs and the digestive system. In the lungs, CF causes severe breathing problems. A build-up of thick mucus makes it difficult to clear bacteria and leads to cycles of infection and inflammation, which damage the delicate lung tissues. They must follow a demanding daily routine of physical therapy to keep the lungs free of congestion and infection.
In the digestive tract, CF makes it extremely difficult to digest and absorb adequate nutrients from food. Thick mucus blocks the ducts of the pancreas, preventing enzymes from reaching the intestines to digest food. Therefore, persons with CF must consume a large number of artificial enzymes (on average 20 pills a day) with every meal and snack, to help them absorb adequate nutrition from their food.
How many Canadians have cystic fibrosis?
It is estimated that one in every 3,600 children born in Canada has CF.
At the present time, approximately 3,500 children, adolescents, and adults with cystic fibrosis attend specialized CF clinics.
What Causes Cystic Fibrosis?
People are born with cystic fibrosis; it is a genetic disorder.
Approximately one in every 25 Canadians carries a defective version of the gene responsible for CF. A carrier has only one copy of the gene responsible for CF. Carriers do not have cystic fibrosis, and can never get the disease. In most cases, they are not even aware that they are carriers, because they do not have cystic fibrosis, or any of its symptoms.
When two people who carry a defective version of the gene responsible for CF have a child, there is:
- a 25% chance that the child will be born with cystic fibrosis;
- a 50% chance that the child will not have CF, but will be a carrier;
- a 25% chance that the child will not have CF, and will not be a carrier.
With each pregnancy, the risks are exactly the same. Two carrier parents may have several children with CF or none at all.
