Overview
Cystic fibrosis (CF) is a complex, inherited disease that affects approximately 70,000 people worldwide. It is characterized by the production of thick, sticky mucus that clogs the airways, digestive tract, and other organs, leading to recurring lung infections, digestive problems, and other complications. CF is caused by mutations in the CFTR (cystic fibrosis transmembrane conductance regulator) gene, which codes for a protein responsible for regulating the movement of salt and water in and out of cells.CF affects people of all ethnicities, but it is more common in people of European ancestry. The disease is usually diagnosed in early childhood, and its symptoms can vary in severity and progression. While there is no cure for CF, modern treatments and therapies have significantly improved the quality of life and life expectancy for people with the condition.
History/Background
The first reported cases of CF date back to the 1930s, but it was not until the 1950s that the disease was identified as a distinct medical condition. In the 1960s, researchers discovered that CF was caused by a genetic mutation, and in the 1980s, the CFTR gene was identified as the primary cause of the disease. Since then, significant advances have been made in understanding the molecular mechanisms of CF and developing effective treatments.Key Information
CF is caused by mutations in the CFTR gene, which codes for a protein responsible for regulating the movement of salt and water in and out of cells. The most common mutation is the F508del mutation, which accounts for approximately 70% of all CF cases. CF affects multiple organs, including the lungs, pancreas, liver, kidneys, and reproductive system. Symptoms can include:* Recurring lung infections and respiratory failure
* Digestive problems, such as malnutrition and bowel obstruction
* Pancreatic insufficiency and diabetes
* Liver disease and cirrhosis
* Reproductive problems, including infertility and menorrhagia
