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.  Cystic Fibrosis. Cystic fibrosis (CF) is a progressive, lifelong condition in which the glands that produce mucus, sweat, and intestinal secretions do not function properly. Thick mucus accumulates in the lungs, leading to breathing difficulty and infection.  Cystic fibrosis is an inherited disease. For someone to get cystic fibrosis, both parents must be carriers of the gene that causes it and then pass it on. That means 25% of the children of such parents will have cystic fibrosis. Boys and girls are equally likely to get the disease. About 10 million Americans carry the gene and do not know it. 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. This makes it increasingly difficult to breathe. Cystic fibrosis is a rare genetic disease, found in about 30,000 people in the United States and 70,000 worldwide. Most children are now screened for CF at birth through newborn screening and the majority are diagnosed by age 2. However, some people with CF are diagnosed as adults.  The CFTR gene provides instructions for making a protein called the cystic fibrosis transmembrane conductance regulator. This protein functions as a channel across the membrane of cells that produce mucus, sweat, saliva, tears, and digestive enzymes.  Cystic fibrosis is an inherited disease characterized by the buildup of thick, sticky mucus that can damage many of the body's organs. The disorder's most common signs and symptoms include progressive damage to the respiratory system and chronic digestive system problems. Mutations in the CFTR gene cause cystic fibrosis. The CFTR gene provides instructions for making a channel that transports negatively charged particles called chloride ions into and out of cells. Cystic fibrosis (CF) is an inherited condition that causes mucus to build up and clog some of the organs in the body, particularly in the lungs and pancreas. When mucus clogs the lungs, it can make breathing very difficult.  Different people may have different degrees of symptoms. CF is an autosomal recessive disorder. It is caused by the presence of mutations in both copies of the gene for the protein cystic fibrosis transmembrane conductance regulator (CFTR). Those with a single working copy are carriers and otherwise mostly normal. The main signs and symptoms of cystic fibrosis are salty-tasting skin, poor growth, and poor weight gain despite normal food intake, accumulation of thick, sticky mucus, frequent chest infections, and coughing or shortness of breath. Cystic fibrosis is an inherited disease which causes mucus in the lungs to be more sticky than normal, leading to frequent lung infections and lung damage. Pneumococcus is a type of bacteria that can cause infection throughout the body, including in the urine, blood stream, fluid around the brain and in the lungs. Cystic fibrosis (SIS-tik fi-BRO-sis), or CF, is an inherited disease of the secretory (see-KREH-tor-ee) glands. Secretory glands include glands that make mucus and sweat. Inherited means the disease is passed from parents to children through gene
