Cystic fibrosis is a recessive disorder. In a recessive disorder, both parents must carry a copy of the abnormal gene for the problem to occur in their child. A person who has one copy of an abnormal gene for a recessive disorder is a carrier for that disorder, even though he or she may show no signs of it.
The CF gene was discovered in 1989 on chromosome pair 7 -- volume 7 in our genetic encyclopedia -- by researchers supported by the CF Foundation. Cystic fibrosis is an example of a recessive disease. That means a person must have a mutation in both copies of the CF gene to have CF.ystic fibrosis is caused by mutations in the gene that produces the cystic fibrosis transmembrane conductance regulator (CFTR) protein. This protein is responsible for regulating the flow of salt and fluids in and out of the cells in different parts of the body.
