About 10% of term neonates present with respiratory distress at birth. The most common aetiologies include transient tachypnoea of the newborn, pneumonia and meconium aspiration syndrome (MAS). Hyaline membrane disease (HMD) in a term infant occurs either as primary HMD, secondary surfactant deficiency or congenital surfactant dysfunction. A detailed history supported with appropriate radiological and laboratory investigations can help a clinician reach a diagnosis. We report a case of surfactant dysfunction disorder which presented as severe MAS and persistent pulmonary hypertension of the newborn. In the infant described, the significant history of a sibling death with severe neonatal respiratory disease led us to think of diffuse developmental lung diseases especially surfactant dysfunction syndromes. Exome sequencing detected a heterozygous missense variation in exon 21 of the ATP binding cassette protein member 3 (ABCA3) gene. Based on the clinical picture supported with the exome sequencing, a diagnosis of surfactant dysfunction disorder (ABCA3 deficiency) was confirmed.
