1 Cystic fibrosis primarily affects the lungs and digestive system. 2  It leads to the production of mucus that is much thicker and more sticky than usual. 3  Cystic fibrosis is a hereditary condition, caused by a defective gene. 4  The cystic fibrosis gene must be present in both parents for a child to have the condition.
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.
