In brief: Sodium channel
Cystic fibrosis or CF is a genetic disorder that affects a sodium channel (salt) in the lining of the airways, sinuses and other organs.
With this abnormality salt and water leave the lumen (center) of the airways resulting in thickening of secretions and airways congestion/pneumonia and poor function.
