Cystic fibrosis (CF)is a disease caused by a mutation in a gene called the cystic fibrosis transmembrane conductance regulator (CFTR). Among other functions, this gene helps create sweat and mucus. There is no cure for CF, and most individuals who have it die in their twenties and thirties. Based on this scenario, what would you conclude about people who have CF?

Quizplus · Accepted Answer

The mutation in the CFTR gene leads to the production of thick, sticky mucus that clogs the lungs and other organs, causing breathing problems and increasing the risk of lung infections. This can lead to lung failure and ultimately, premature death. Incessant coughing is a common symptom of CF. Other symptoms may include digestive issues, infertility, and salty-tasting skin, but none of the answer choices mention these specific symptoms.
