At least 10 million Americans carry the defective gene for Cystic fibrosis; there are more than 1,000 mutations of this gene. Cystic Fibrosis affects mainly the lungs and digestive system in children and young adults. In the first year of life 60% of patients are diagnosed and 90% by age 10.

In the early 1980's scientists started looking for the cause of cystic fibrosis. After a lot of hard work the scientist finally started to isolate the gene and find what mutations caused the gene. In the 1940's doctors realized that people with cystic fibrosis had clogged ductual systems with thick mucus. In 1946 scientists discovered that people with the disease had two recessive copies of the gene. In the 1980'scientist found a malfunction of the epithelial tissue which keeps the...
