Open in a separate window Disease characteristics CF affects epithelia of the respiratory tract, exocrine pancreas, intestine, hepatobiliary system, male genital tract, and exocrine sweat glands, resulting in complex multiorgan disease. Pulmonary disease is the major cause of morbidity and mortality in CF. Affected individuals have lower airway inflammation and chronic endobronchial infection, progressing to end-stage lung disease characterized by extensive airway damage bronchiectasis, cysts, and abscesses and fibrosis of lung parenchyma.

The causes manifestation and genetic detection of cystic fibrosis

Cystic fibrosis CF is a condition that affects breathing and digestion. Mucus is a fluid that normally coats and protects parts of the body. But in CF, the mucus is thicker and sticky. It builds up in the lungs and digestive system and can cause problems with how you breathe and digest food.

CF affects about 30, children and adults in the United States. It is one of the most common genetic conditions in this country. About 1 in 3, babies is born with CF.

Clinical practice and genetic counseling for cystic fibrosis and CFTR-related disorders

Genes come in pairs—you get one of each pair from each parent. Sometimes the instructions in genes change. This is called a gene change or a mutation. Parents can pass gene changes to their children. Sometimes a gene change can cause a gene to not work correctly. Sometimes it can cause birth defects or other health conditions.

A birth defect is a health condition that is present in a baby at birth. Your baby has to inherit a gene change for CF from both parents to have CF.


When this happens, your baby is called a CF carrier. What problems does CF cause? Babies with CF have very thick and sticky mucus that builds up in the body. When this mucus builds up in the lungs, it blocks airways and causes breathing problems and infections. Airways are tubes that carry air in and out of the lungs.

As a baby with CF gets older, lung infections can get worse.A mutation in the cystic fibrosis transmembrane conductance regulator gene associated with elevated sweat chloride concentrations in the absence of cystic fibrosis.

Hum Mol Genet. ; – This gene, called the “cystic fibrosis transmembrane conductance regulator” gene, or CFTR gene, 3 is located on human chromosome 7, and is made up of , DNA nucleotides. 4 The CFTR gene produces a protein . Cystic fibrosis (CF) is the most common life limiting genetic disorder of white populations.

There are over patients in the UK with this condition and at least 30 in the USA. 1 This review focuses on the challenges of diagnosis, clinical complications, and management. May 22,  · 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.

What Causes Cystic Fibrosis?

Since the detection of the underlying gene defect, our knowledge of how the genetic mutations in cystic fibrosis cause lung disease has increased substantially, but we still lack a complete under- standing of some of the pieces in the puzzle. 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. The most commonly affected organs include the: lungs; pancreas; liver; intestines; Cystic fibrosis affects the cells that produce sweat, mucus, and digestive .
