Abstract | RATIONALE: Mutations in genes encoding proteins important in the function and metabolism of pulmonary surfactant are recognized causes of lung disease. Clinical genetic testing is available for these disorders, but children with phenotypes consistent with surfactant dysfunction and no identifiable mutations in the known causative genes have been reported. OBJECTIVES: METHODS: Amplicons spanning multiple exons of candidate genes were generated by polymerase chain reaction and sequenced. MEASUREMENTS AND MAIN RESULTS: CONCLUSIONS: Large deletions are a cause of surfactant dysfunction disorders and may need to be sought for specifically in children whose phenotypes suggest these syndromes but in whom clinical genetic testing is unrevealing.
