Abstract
OVERVIEW: Cystic fibrosis (CF) is an autosomal recessive disorder that was long considered a terminal illness. Recent genetic discoveries and genomic innovations, however, have transformed the diagnosis, classification, and treatment of this multisystem condition. For affected patients, these breakthroughs offer hope for significantly greater longevity and quality of life and, perhaps, for a future cure. This article reviews empirical research on CF, filling a critical gap in the nursing literature regarding recent findings in the study of CF genetics and their implications for patient teaching, diagnosis, and treatment.
