A New ABCA3 Gene Mutation c.3445G>A (p.Asp1149Asn) as a Causative Agent of Newborn Lethal Respiratory Distress Syndrome.

ABSTRACT: Mutations in adenosine triphosphate-binding cassette transporter A3 (ABCA3) (OMIM: 601615) gene constitute the most frequent genetic cause of severe neonatal respiratory distress syndrome (RDS) and interstitial lung disease (ILD) in children. Interstitial lung disease in children and especially in infants, in contrast to adults, is more likely to appear as a result of developmental deficits or is characterized by genetic aberrations of pulmonary surfactant homeostasis not responding to exogenous surfactant administration. The underlying ABCA3 gene mutations are commonly thought, regarding null mutations, to determine the clinical course of the disease while there exist mutation types, especially missense variants, whose effects on surfactant proteins are difficult to predict. In addition,
