Understanding the mutation that produces your particular version of CF is more than scientific curiosity; it holds the key to the progression of the disease and the treatments that may change the course of that progression.
The Cystic Fibrosis Foundation (CFF) provides many information resources to promote knowledge on the cystic fibrosis transmembrane conductance regulator (CFTR) mutation. Their latest entry into the library is a two-sided single sheet flyer that gives an excellent snapshot of the four classes of mutation, their physiology and the emerging treatments designed to correct these defects. Check out Know-Your-CFTR-Mutations.
The above link will give you the option to download the flyer. The document is a good starting point for familiarizing yourself with the science that describes CF, and educating family and friends.
