Overview
Cystic fibrosis is a complex and life-threatening genetic disorder that affects approximately 70,000 people 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 leads to the production of thick, sticky mucus that clogs the lungs and digestive tract, causing a range of symptoms and complications. While there is no cure for CF, advances in medical treatment and care have significantly improved the quality of life and life expectancy for those affected.History/Background
The first reported cases of cystic fibrosis date back to the 1930s, but it was not until the 1950s and 1960s that the condition began to be recognized as a distinct medical entity. In 1959, Dr. Van Allen and Dr. Doan identified the condition as a genetic disorder, and in the 1970s, the CFTR gene was first isolated. Since then, research has led to a greater understanding of the condition and the development of new treatments, including pulmonary rehabilitation, gene therapy, and stem cell transplantation.Key Information
Cystic fibrosis is characterized by a range of symptoms, including:* Respiratory problems: persistent coughing, wheezing, and shortness of breath
* Digestive problems: abdominal pain, bloating, and malnutrition
* Reproductive problems: infertility and recurrent miscarriage
* Other complications: sinusitis, bronchiectasis, and liver disease
Key facts about cystic fibrosis include:
* 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.
* Prevalence: CF affects approximately 1 in 2,500 to 1 in 3,500 people worldwide.
* Life expectancy: with modern treatment and care, people with CF can live into their 40s and 50s.
