What is Cystic Fibrosis? The "Grey Zone"

This is a very short video (with Pediatric Pulmonologist - Alfin G. Vicencio, MD) about the cystic fibrosis "grey zone" and how this complicates CF diagnosis. The "grey zone" relates to patients who do not present with the typical symptoms of cystic fibrosis but still have illness creating mutations on their cystic fibrosis transmembrane conductance regulator (i.e. the cystic fibrosis gene - also called the CFTR gene). This leads to atypical forms of cystic fibrosis and extends the boundaries of what "cystic fibrosis" is and how it affects people.
