Cystic Fibrosis

**Etiology: Cystic Fibrosis is carried as a recessive trait by approximately 3 percent of the white population. The responsible gene is located on the long arm of chromosome 7. It encodes a membrane-associated protein called the cystic fibrosis transmembrane conductance regulator (CFTR).

**Signs/Symptoms: Symptoms of Cystic Fibrosis affect different people in different ways and to varying degrees. However, the basic problem is the same-an abnormality in the glands which produce or secrete sweat and mucus. Cystic Fibrosis also causes other medical problems such as repeated infections, recurrent pneumonia, chronic cough, wheezing, bronchitis, chronic sinusitis, asthma, fatigue, abdominal pain, etc.
