Cystic Fibrosis
Definition
Cystic fibrosis is a genetic disorder that affects the respiratory, digestive, and reproductive systems. It is characterized by the production of thick, sticky mucus that can obstruct airways and lead to chronic lung infections, as well as impair the function of the pancreas and other organs. The condition is caused by mutations in the CFTR gene, which regulates the movement of salt and water in and out of cells.
