Cystic fibrosis is a genetic disorder characterized by thick, viscous secretions across the epithelium. This disease affects the lungs, pancreas, liver, and intestines. Cystic fibrosis is caused by a mutation to the CFTR gene that is responsible for regulating the components of mucus. The CFTR gene is located on chromosome 7. It has 230,000 base pairs and creates a protein that is 1,480 amino acids long. One of the most common mutations of the CFTR gene is a deletion that eliminates three nucleotides.
