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).
Overview of Cystic Fibrosis. Cystic fibrosis (CF) is the most common fatal, inherited disease in the United States (see Incidence). CF causes the body to produce abnormally thick and sticky mucus in several different parts of the body, most prominently in the lungs and other parts of the respiratory system.It also affects the pancreas, leading to serious digestive problems. Cystic fibrosis alters the mucus secretions of the body's epithelial cells.ust as the chromosomes come in pairs, so do the genes: one copy of the gene on one chromosome is from the mother, the other copy on the other chromosome from the father. The defective gene that is responsible for causing cystic fibrosis is on chromosome 7.
