Expert Solution
Introduction:
- Mutations in the CFTR gene lead to the genetic condition known as cystic fibrosis (CF).
- The CFTR gene encodes a cystic fibrosis transmembrane conductance regulator (CFTR) protein that controls the movement of salt and water into and out of cells.
- Mutations in the CFTR gene result in the production of a dysfunctional or absent protein, which causes typical CF symptoms.
