Cystic Fibrosis is genetic disease that is caused by a mutation in the protein fibrosis transmembrane conductance regulator gene (CFTR).
Cystic Fibrosis affects the intestine, lungs, pancreas and liver. It results from chloride and sodium transporting abnormally across epithelium (a type of human tissue) resulting in thick secretions.
Cystic Fibrosis can lead to the formation of cysts and scarring (fibrosis) in the pancreas as well as lung infections. Other symptoms include poor growth patterns, diarrhea, sinus infections and infertility.
