Study Notes
Cystic Fibrosis Overview
- Cystic fibrosis (CF) is a genetic disorder affecting the respiratory, digestive, and reproductive systems.
- CF is caused by mutations in the CFTR gene, impairing salt and water movement in cells, leading to thick mucus buildup.
- The CFTR gene is located on chromosome 7.
- A common mutation is AF508.
- CF primarily affects the lungs, causing chronic infections and difficulty breathing.
- CF also impacts the digestive system, hindering nutrient absorption (malnutrition) and causing poor growth.
- CF can affect reproductive organs, potentially causing infertility in males.
Effects of Cystic Fibrosis
- Respiratory: Persistent coughing, frequent lung infections, inflamed nasal passages, recurrent sinusitis, wheezing and shortness of breath.
- Digestive: Greasy, foul-smelling stools, weight loss, loss of appetite, inability to tolerate exercise.
- Other: Salty-tasting skin.
Cystic Fibrosis Data and Facts
- CF is a common genetic disorder amongst people of European ancestry.
- The incidence rate is approximately 1 in 2,500-3,500 live births in the United States.
- Life expectancy has improved, with many living into their 40s or 50s.
- Disease severity varies widely.
Recent Discoveries and Treatments
- CFTR Modulators: New drugs like Trikafta improve CFTR protein function, boosting lung health, and reducing symptoms.
- Gene Therapy: Research aims to correct the CFTR mutation through gene therapy, potentially offering a cure.
