Cystic fibrosis is a genetic disorder that affects the respiratory and digestive systems. People with cystic fibrosis inherit a defective gene on chromosome 7 called CFTR (cystic fibrosis transmembrane conductance regulator).
Scientists estimate that about 12 million Americans are currently CF carriers. If two CF carriers have a child, there is a 1 in 4 chance that the child will have CF. Almost 1,400 different mutations of the CF gene can lead to cystic fibrosis (some mutations cause milder symptoms than others). About 70% of people with CF have the disease because they inherited the mutant gene Delta F508 from both of their parents.
