The Cystic Fibrosis Gene


Cystic fibrosis is an inherited autosomal recessive disease that exerts its main effects on the digestive system and the lungs. This disease is the most common lethal genetic disorder in Caucasians, affecting one out of 2,500. On the bioethical front, CF was the first human genetic disease to be cloned by geneticists. The intent of this paper is to describe how the cystic fibrosis gene was identified, how the gene is defective, its physical manifestations, and to discuss possible treatments of the disease.
The classical approach to finding the gene that is responsible for causing a genetic disease is to first characterize the bio-chemical defect within the gene, then to identify the mutated protein in the gene, and finally to locate the actual gene. However, this classical approach proves to be impractical when searching for the CF gene. To find the gene responsible for CF, the principle of "reverse......
