New Research Has Broadened the Number of Clinically Relevant CFTR Gene Mutations.
Imagine yourself suspended a couple of hundred feet below the surface of the ocean. The sheer weight of the immense column of water pushing down on your chest makes each breath a harrowing task. Now picture that your only recourse to collect vital oxygen is to breathe laboriously throw a narrow straw that connects you to the atmosphere above. You slowly draw in air, cautiously trying not to collapse the straw from too forceful of suction—struggling just as much to exhale the expired air. Now repeat the entire cycle for the rest of your life.
If you were able to envision how the immense difficulties of breathing in this manner would be for just a few minutes, let alone your entire life, then you may have a minute sense of what a person afflicted with cystic fibrosis (CF) endures. Gasping for air while thick, sticky mucus lines the pulmonary system, seemingly threatening to drown and suffocate patients with each inhale.
