{Abstract}: <B>BACKGROUND: </B>Congenital surfactant deficiency, often caused by mutations in genes involved in surfactant biosynthesis such as ABCA3, presents a significant challenge in neonatal care due to its severe respiratory manifestations. This study aims to analyze the clinical data of a newborn male diagnosed with pulmonary surfactant metabolism dysfunction type 3 resulting from ABCA3 gene mutations to provide insights into the management of this condition.<BR><B>METHODS: </B>A newly born male child aged 1 day and 3 hours was referred to our department due to poor crying and shortness of breath.<BR><B>METHODS: </B>Primary diagnoses by the duty physicians were: neonatal pneumonia, neonatal respiratory failure, persistent neonatal pulmonary hypertension, birth asphyxia, myocardial damage, and arteriovenous catheterization. Genetic test revealed a compound heterozygous variant in the ABCA3 gene. One allele may be exon variant c.4561C>T, the second allele may be intron variant c.1896 + 2_1896 + 17del. The associated disease included pulmonary surfactant metabolism dysfunction type 3.<BR><B>METHODS: </B>He was initially treated with an antiinfective therapeutic regimen.<BR><B>RESULTS: </B>The family was informed of this condition and signed off, and the child died.<BR><B>CONCLUSIONS: </B>Hereditary pulmonary surfactant deficiency is a rare and untreatable disease. The case highlights the challenges in managing congenital surfactant deficiencies and emphasizes the need for heightened awareness of this rare cause of infant respiratory failure.
