Cystic Fibrosis – Overview and Genetics
Cystic fibrosis (CF) is a genetic disorder that affects the lungs, digestive system, and other parts of the body. Mutations in the CFTR gene on chromosome 7 leads to the production of thick, sticky mucus that can block airways and digestive ducts. Patients deal with lung infections and lack of nutrition because the mucus interferes…
