Overview
Cystic fibrosis (CF) is a rare, inherited disorder that affects approximately 70,000 people in the United States and 75,000 worldwide. It 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. This leads to the production of thick, sticky mucus that clogs the lungs, digestive tract, and other organs, causing a range of symptoms and complications.CF affects people of all ages, from infants to adults, and is more common in people of European descent. The disease is characterized by recurring respiratory infections, digestive problems, and malnutrition due to impaired nutrient absorption. Without proper treatment, CF can lead to life-threatening complications, such as respiratory failure, heart disease, and liver disease.
History/Background
The first recorded description of CF dates back to 1938, when Dr. Dorothy Andersen, an American pediatrician, described the condition as a "fibrocystic disease of the pancreas." However, it wasn't until the 1950s and 1960s that the genetic basis of CF was discovered. In 1989, the CFTR gene was identified, and since then, numerous genetic mutations have been linked to the disease. Advances in medical research and treatment have significantly improved the quality of life for people with CF, but it remains a challenging condition to manage.Key Information
Key facts about cystic fibrosis include:- Genetic inheritance: CF is inherited in an autosomal recessive pattern, meaning that a person must inherit two copies of the mutated gene (one from each parent) to develop the condition.
- Symptoms: Common symptoms include persistent coughing, wheezing, and shortness of breath, as well as digestive problems, such as abdominal pain and greasy stools.
- Complications: Untreated CF can lead to life-threatening complications, such as respiratory failure, heart disease, and liver disease.
- Treatment: Treatment options include medications to thin mucus, antibiotics to prevent infections, and enzyme replacement therapy to improve nutrient absorption.
