Overview
Cystic fibrosis is a life-threatening genetic disorder that affects approximately 70,000 people in the United States and over 80,000 worldwide. It 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. This mutation leads to the production of thick, sticky mucus that clogs the airways, digestive tract, and other organs, causing a range of symptoms and complications.
Cystic fibrosis is a complex condition that affects multiple systems in the body. Respiratory problems are the most common and severe symptoms, including chronic coughing, wheezing, and shortness of breath. Digestive issues, such as malabsorption and frequent bowel movements, are also common. Additionally, people with CF may experience reproductive problems, sinus infections, and pancreatitis.
History/Background
Cystic fibrosis was first described in 1938 by Dr. Dorothy Andersen, an American pathologist who identified the condition as a distinct entity. However, the genetic basis of CF was not understood until the 1980s, when researchers discovered the CFTR gene. Since then, significant advances have been made in understanding the underlying biology of CF and developing treatments to manage the condition.
Key Information
Cystic fibrosis is a genetic disorder that 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. The most common symptoms of CF include:
* Respiratory problems: Chronic coughing, wheezing, and shortness of breath
* Digestive issues: Malabsorption, frequent bowel movements, and abdominal pain
* Reproductive problems: Infertility, miscarriage, and stillbirth
* Sinus infections: Frequent and recurring sinus infections
* Pancreatitis: Inflammation of the pancreas
Significance
Cystic fibrosis is a significant public health concern, with a median life expectancy of 47 years for people with the condition. However, with advances in treatment and care, many people with CF are living into their 50s and 60s. The development of gene therapy and stem cell therapy holds promise for future treatments and potentially a cure for CF.
