Satisfactory Essays
What is Cystic Fibrosis? Cystic Fibrosis, also called CF, is a genetic disease. This disease is caused when one has inherited two copies of a faulty gene, one coming from each parent; and it affects mainly the lungs. This disease is usually detected at birth, and is currently not curable. It can be found in many ethnic groups, but mainly found in Caucasians. With the proper care, the average survival rate of someone with CF is age 40. Known Causes? Cystic Fibrosis is a genetic disease caused by a defective CF gene. There has to be one copy of this defective gene in each parent in order for a child to have this disease. The defective gene is called cystic fibrosis transmembrane conductance regulator gene or CFTR gene. This gene controls…show more content…

When in the lungs this mucus clogs the airways and traps bacteria. This can lead to lung infections (also caused by bacteria), lung damage, helps germs grow and multiply, and later can cause respiratory failure. When in the pancreas the mucus buildup prevents the release of digestive enzymes that allows the body to break down food and absorb nutrients. This can lead to difficulty absorbing food and nutrients, which can lead to poor weight gain. The mucus caused by CF can also cause liver disease, and can affect a male’s ability to have
