By replacing the abnormal gene with a copy of the normal gene.

Gene therapy for cystic fibrosis delivers a functional CFTR gene (usually via a viral or nonviral vector) to the patient's airway cells so they can produce working CFTR protein. This restores chloride transport rather than inducing mutations, adding single bases, or removing gene portions.
