CFTR protein facilitates the transport of chloride ions and water across the cells. Genetic defect in the CFTR gene results in defective protein synthesis. This defect in CFTR protein disrupts the chloride and water channel across the cell. The CFTR protein acts as a channel across the cell membranes which are specialized to produce mucus, sweat, tears etc. Failure of transport channel will result in symptoms like secretion of thick mucus. This mucus can obstruct the airflow and glands resulting in symptoms of cystic fibrosis.
