Unexplained neonatal respiratory distress due to congenital surfactant deficiency.
J Pediatr. 2007 Jun;150(6):649-53, 653.e1., [PMID:17517255]

Abstract [show]
Genetic abnormalities of pulmonary surfactant were identified by DNA sequence analysis in 14 (12 full-term, 2 preterm) of 17 newborn infants with fatal respiratory distress of unknown etiology. Deficiency of adenosine triphosphate-binding cassette protein, member A3 (n = 12) was a more frequent cause of this phenotype than deficiency of surfactant protein B (n = 2).

42 Conservation of codons between orthologs (canis, mus, rattus, fugu, drosophila) was evaluated on amino acid sequences aligned using computer software (data not shown).10 Two of the missense mutations (R155Q and R208W) were found on more than 1 affected chromosome in unrelated patients.
