What Causes Cystic Fibrosis?

Content

Cystic fibrosis is caused by mutations of the CFTR gene – cystic fibrosis transmembrance conductance regulator – which was discovered by Francis Collins in 1989. Since that time, over 1900 defects in this gene have been identified.

The normal CFTR protein functions as a channel allowing the passage of salt and water into and out of the cell appropriately. This channel is defective in CF patients preventing the normal passage of salt and water and leading to thick, sticky mucus throughout the body. This mucus blocks airways, intestines, gallbladder and many other tubes in the body. This eventually results in difficulty breathing and absorbing nutrients.

Genetics of Cystic Fibrosis

Content

Cystic Fibrosis is a recessive disease, meaning that both copies of the gene (one from the mother and one from the father) must be defective in order to be diagnosed with CF. Defects in the CFTR is the most common genetic mutation found in the Caucasian population, about 1 in 25 people have one defective gene. Having one defective gene does not give you CF. Each time two carriers of the defective gene conceive, there is a:

  • 1 in 4 chance that their child will not have the gene at all
  • 1 in 2 chance that their child will inherit one defective gene and be a carrier but not have the disease
  • 1 in 4 chance that their child will have cystic fibrosis

Symptoms of Cystic Fibrosis

Content

The most prevalent indicator of cystic fibrosis is the overabundance of thick, sticky mucus in the airways. Normally, in the lungs, mucus performs several functions including being a protective barrier helping to prevent infection and transporting dust and other particles out of the bronchial tubes. Symptoms include:

  • Persistent cough
  • Frequent lung infections
  • Wheezing
  • Thick, sticky phlegm
  • Shortness of breath

Gastrointestinal Symptoms

  • Pancreatic insufficiency - abdominal pain, diarrhea, bloating
  • Pancreatitis
  • Acid reflux
  • Malabsorption - weight loss, diarrhea
  • Bowel obstruction
  • Meconium ileus - present at birth

Other Symptoms

  • Salty sweat or skin
  • Clubbing of the fingers
  • Fatigue
  • Nasal polyps
  • Sinusitis
  • Poor growth, weight loss
  • Male infertility

Testing for Cystic Fibrosis

Content

A person who has a family history of cystic fibrosis or exhibits symptoms of the disease may undergo a sweat test, which measures the concentration of salt in a person’s sweat. Simple and painless, the test should be administered by a Cystic Fibrosis Foundation-accredited care center where strict guidelines help ensure the accuracy of the results.

Newborn Screening

Content

All 50 states have protocols in place to test every newborn for certain diseases in which early intervention is beneficial. This is accomplished by a simple blood sample obtained from a heel stick prior to discharge from the hospital. Cystic fibrosis is part of this protocol in every state as of 2009.

Research

Content

The Therapeutic Development Network is a designation given to clinical centers by the Cystic Fibrosis Foundation for expertise in clinical trial research. We are one of the 77 in the United States which has received this designation.

Center patients benefit from centralized training, standardized procedures and access to the newest clinical trials because of the TDN designation. Our center, along with other TDCs, uses quality improvement tools and strategies on an ongoing basis, and our performance in clinical studies is monitored to encourage continued quality and efficiency without compromising safety.
