Cystic Fibrosis

Cystic Fibrosis is a fatal genetic disorder that effect’s many organ systems in the body. It is estimated that CF effects 30,000 adults and children in the United States, with approximately 1,000 new cases diagnosed each year. Cystic Fibrosis is most prevalent among white but affects all ethnic groups. Cystic Fibrosis results from an autosomal recessive gene mutation of the Cystic Fibrosis transmembrane conductance regulator (CFTR) protein located on chromosome 7. The CFTR gene makes a protein that controls the movement of salt and water in an out of your body’s cells. Normally secretions from the body’s exocrine glands (sweat, tears, saliva, digestive juices, and mucus) are thin and slippery. People with CF there secretions are thick and prevent proper functioning of several organs. Cystic Fibrosis is inherited by one or both parent’s every person inherits two CFTR genes, one from each parent. Children who inherit a faulty CFTR gene from each parent will have CF. Children who inherit one faulty CFTR gene and one normal CFTR gene are ‘CF carriers’. CF carriers usually have no symptoms of CF and live normal lives, however they can pass the faulty CFTR gene to their children. Signs & Symptoms

One of the first signs of CF that parents may notice is that their baby’s skin tastes salty when kissed, or the baby doesn’t pass stool when first born. CF signs and symptoms vary, depending on the severity of the disease. Even in the same person, symptoms may worsen or improve as time passes.
