Background Information
CFTR is a member of the ATP-binding cassette (ABC) family of membrane transport proteins, functioning as a chloride channel responsible for ion flow across epithelial surfaces of lung, sinuses, pancreas, intestine, and liver. Mutations of CFTR cause cystic fibrosis (CF), a disorder affecting the respiratory, digestive, reproductive systems and sweat glands.
