Root Cause of Cystic Fibrosis
Cystic fibrosis is a genetic disorder. It is characterized by chronic lung inflammation. The root cause of CF is a mutation in the CFTR gene. The product of this gene is a chloride ion channel. The most common mutation is ∆F508, a deletion of 3 base pairs at a specific point in the genome.
