Summary
Severe chronic rhinosinusitis in children may indicate underlying cystic fibrosis transmembrane conductance regulator (CFTR) gene mutations. Early CFTR genotyping and assessment can identify treatable conditions and prevent lung infections.
Area of Science:
- Pediatric Otolaryngology
- Genetics
- Pulmonology
Background:
- Severe chronic rhinosinusitis (CRS) in children is a complex condition with various potential underlying causes.
- The cystic fibrosis transmembrane conductance regulator (CFTR) gene plays a crucial role in maintaining airway health.
Observation:
- Children with severe CRS may present with undiagnosed genetic conditions affecting mucociliary clearance.
- Extensive CFTR genotyping is a key diagnostic step in evaluating these severe cases.
Findings:
- Identifying rare CFTR mutations in children with severe CRS is clinically significant.
- These mutations can be targeted with specific CFTR modulator therapies.
Implications:
- Early diagnosis of CFTR-related disorders through genotyping can lead to timely treatment.
- Targeted therapies may help manage CRS symptoms and potentially postpone serious pulmonary complications.
- This approach highlights the importance of a comprehensive clinical and functional evaluation in pediatric severe CRS.

Cystic fibrosis (CF), an autosomal recessive disorder, significantly affects the function of exocrine glands. This genetically inherited disease is characterized by the production of thick and sticky mucus, which can severely affect various organs and systems in the body.
CF is primarily caused by a genetic mutation in a chromosome 7 gene coding for the cystic fibrosis transmembrane conductance regulator (CFTR) protein. The most common gene mutation leading to CF is the ΔF508 mutation,...

Cystic fibrosis (CF) is an autosomal recessive disorder that predominantly affects individuals of Northern European descent, occurring at a rate of 1 in 3500. It is caused by a genetic mutation in a gene on chromosome 7, most commonly the ΔF508 mutation, that codes for the cystic fibrosis transmembrane conductance regulator (CFTR) protein. This results in thicker mucus secretions and obstruction pathologies in multiple organs, including the lungs and sinuses.
