- The cause of cystic fibrosis (CF) is a defect in a gene called the cystic fibrosis transmembrane conductance regulator (CFTR) gene. This gene makes a protein that controls the movement of salt and water in and out of the cells in your body.

- Cystic fibrosis is a genetic condition caused by a faulty gene (known as the CFTR gene). The CFTR gene normally creates a protein that moves salt and water out of a cell.If the CFTR gene is defective, it results in a build-up of thick, sticky mucus in the body's tubes and passageways.These blockages damage the lungs, digestive system and other organs, resulting in inflammation (swelling) and, in the lungs, repeated infections.f the CFTR gene is defective, it results in a build-up of thick, sticky mucus in the body's tubes and passageways.

Cystic fibrosis It is caused by the presence of mutations in both copies of the gene for the cystic fibrosis transmembrane conductance regulator (CFTR) protein. Those with a single working copy are carriers and otherwise mostly normal. CFTR is involved in production of sweat, digestive fluids, and mucus.

- A defect in the CFTR gene causes cystic fibrosis (CF). This gene makes a protein that controls the movement of salt and water in and out of your body's cells. In people who have CF, the gene makes a protein that doesn't work well. This causes thick, sticky mucus and very salty sweat.

- Cystic fibrosis (CF) is an inherited disease that causes the body to produce mucus that's extremely thick and sticky. It mainly affects the lungs and the pancreas, causing serious breathing and digestive problems.

Organizing Your Social Sciences Research Paper: Independent and Dependent Variables Many people have trouble remembering which is the independent variable and which is the dependent variable. An easy way to remember is to insert the names of the two variables you are using in this sentence in they way that makes the most sense. (Independent variable) causes a change in (Dependent Variable) and it isn't possible that (Dependent Variable) could cause a change in (Independent Variable).

Facts About Cystic Fibrosis Cystic fibrosis (CF) is a chronic, progressive, and frequently fatal genetic (inherited) disease of the body's mucus glands. CF primarily affects the respiratory and digestive systems in children and young adults.

CF Genetics: The Basics The CF gene was discovered in 1989 on chromosome pair 7 -- volume 7 in our genetic encyclopedia -- by researchers supported by the CF Foundation. Cystic fibrosis is an example of a recessive disease. That means a person must have a mutation in both copies of the CF gene to have CF.ystic fibrosis is caused by mutations in the gene that produces the cystic fibrosis transmembrane conductance regulator (CFTR) protein. This protein is responsible for regulating the flow of salt and fluids in and out of the cells in different parts of the body.

- Cystic Fibrosis (CF) Overview. Overview of Cystic Fibrosis. Cystic fibrosis (CF) is the most common fatal, inherited disease in the United States (see Incidence). CF causes the body to produce abnormally thick and sticky mucus in several different parts of the body, most prominently in the lungs and other parts of the respiratory system.

Cystic Fibrosis If a genetic test or blood test suggests CF, a doctor will confirm the diagnosis using a sweat test. This test is the most useful test for diagnosing CF. A sweat test measures the amount of salt in sweat. For this test, the doctor triggers sweating on a small patch of skin on an arm or leg.

What Causes CF Scientists estimate that about 12 million Americans are currently CF carriers. If two CF carriers have a child, there is a 1 in 4 chance that the child will have CF. Almost 1,400 different mutations of the CF gene can lead to cystic fibrosis (some mutations cause milder symptoms than others). About 70% of people with CF have the disease because they inherited the mutant gene Delta F508 from both of their parents.

What is CFTR, and what's its relation to cystic fibrosis? Cystic fibrosis is caused by a mutation on the CFTR gene (cystic fibrosis transmembrane conductance regulator gene) on chromosome 7 (7q31.2).

Overview Causes. In cystic fibrosis, a defect (mutation) in a gene changes a protein that regulates the movement of salt in and out of cells. The result is thick, sticky mucus in the respiratory, digestive and reproductive systems, as well as increased salt in sweat. Many different defects can occur in the gene.

Cystic fibrosis Causes. Cystic fibrosis (CF) is a disease that is passed down through families. It is caused by a defective gene that makes the body produce abnormally thick and sticky fluid, called mucus.This mucus builds up in the breathing passages of the lungs and in the pancreas.ystic fibrosis (CF) is a disease that is passed down through families.

Diatomic molecule Diatomic molecules are molecules composed of only two atoms, of either the same or different chemical elements. The prefix di-is of Greek origin, meaning two.If a diatomic molecule consists of two atoms of the same element, such as hydrogen (H 2) or oxygen (O 2), then it is said to be homonuclear.Otherwise, if a diatomic molecule consists of two different atoms, such as carbon monoxide (CO) or nitric oxide (NO), the molecule is said to be heteronuclear.f a diatomic molecule consists of two atoms of the same element, such as hydrogen (H 2) or oxygen (O 2), then it is said to be homonuclear.

Cystic Fibrosis Cystic fibrosis is a serious genetic condition that causes severe damage to the respiratory and digestive systems. This damage often results from a buildup of thick, sticky mucus in the organs. Cystic fibrosis affects the cells that produce sweat, mucus, and digestive enzymes.

- Airways of a person with CF. Because water and salt can't flow freely into or out of cells, the inside of the airways of a person with CF is not as moist as the inside of the airways of a person who does not have CF. This makes it difficult for the cilia to sway freely and sweep the mucus from the lungs.

Cystic fibrosis CF is inherited in an autosomal recessive manner. It is caused by the presence of mutations in both copies of the gene for the cystic fibrosis transmembrane conductance regulator (CFTR) protein. Those with a single working copy are carriers and otherwise mostly normal. CFTR is involved in production of sweat, digestive fluids, and mucus.

Cystic Fibrosis Cystic fibrosis is a genetic disease, meaning it is caused by a person's genes. It affects the glands that produce mucus and sweat, causing mucus to become thick and sticky. As the mucus builds up, it can block airways in the lungs.

Cystic Fibrosis Cystic fibrosis (CF) is the most common fatal genetic disease in the United States today. It causes the body to produce a thick, sticky mucus that clogs the lungs, leading to infection, and blocks the pancreas, stopping digestive enzymes from reaching the intestines where they are required to digest food.
