Cystic Fibrosis
Cystic Fibrosis Cystic Fibrosis is a genetic disease that affects the lungs and the digestive system. Because this disease limits breathing ability, it is a life-threatening disease. In the United States alone, 30,000 people have cystic fibrosis and 1,000 new cases of CF are diagnosed every year. Over half the of the people with CF are over the age of 18. (About Cystic Fibrosis)
Cystic Fibrosis is caused by a mutated gene that changes the protein that controls the salt in and out of the cell. There are many different mutation which can change the severity of the disease in each case. For this to be passed on a child must receive one copy of the gene from each parent to develop this disease. If a child receives a copy from only one parent then

Caused by a the gene CFTR that is attached to chromosome 7. This gene produces the protein CFTR that is associated with the ATP Binding Cassette family which controls transmembrane transporting. CFTR is an anion and uses the ion channel to allow flow of those ions in and out of the cell. Meaning, it plays a specific role in absorption and secretion. When this gene has been mutated, it is unable to perform effectively, leaving exocrine based organs unprotected. (Human Genome Cystic Fibrosis)

During this process, the blood is tested for higher levels of immunoreactive trypsinogen or IRT. The sweat test is another test used to test the amount of salt in the sweat and see if it is higher than normal. A blood test can also check the DNA to see if the gene that can cause Cystic Fibrosis is defected. These tests are usually done on infants and they must be tested at Cystic Fibrosis specialized clinic. (Mayo Clinic Staff)
Today the life expectancy for someone with cystic fibrosis is their 40’s. Which is a massive improvement considering 50 years ago, people with this only survived through elementary school.

948 Words | 4 PagesDiscovered in 1989, Cystic Fibrosis is the most common, fatal genetic disease in the United States. Statistics show that 30,000 people in the US have been named with this disease. (Genome) Cystic Fibrosis is a disease caused when the CFTR (Cystic Fibrosis Transmembrane Regulator) is defective and the cells do not release the right amount of chloride. This causes for the body to produce thick, sticky mucus that clogs up the lungs, leads to infection, blocks the pancreas, which stops the digestive enzymes from reaching the intestine. Symptoms require; salty tasting skin, wheezing, shortness of breath, persistent coughing, poor growth or weight gain, frequent/bulky stool, and male infertility.

Cystic Fibrosis: A Genetic Disease
625 Words | 3 PagesWhen 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
Cystic Fibrosis Research Paper
966 Words | 4 PagesBut what causes this disease? The production of the thick and sticky mucus occurs because of a mutations in a gene on chromosome 7. Cystic Fibrosis happens because of mutations in the gene that makes a protein called CFTR or “Cystic Fibrosis Transmembrane Regulator”. Cystic Fibrosis patients either produce uncommon CFTR protein or no CFTR protein at all. This mutation causes your body to make a thick and sticky mucus, instead of the thin and watery mucus that your body needs to function efficiently and healthy.
