A Comprehensive Compilation of Data on the Relationship Between Surfactant Protein-B (SFTPB) Polymorphisms and Susceptibility to Neonatal Respiratory Distress Syndrome.

ABSTRACT

BACKGROUND: This study aims to explore the association between variations in the Surfactant Protein-B (SFTPB) gene and the risk of neonatal respiratory distress syndrome (NRDS). METHODS: A comprehensive literature search was conducted across PubMed, Scopus, EMBASE, and CNKI databases up to February 10, 2024, to identify pertinent studies. RESULTS: A total of seventeen studies examining the +1580 C/T polymorphism (2,058 cases and 2,596 controls) and five studies investigating the -18 A/C polymorphism (680 cases and 739 controls) were included in the analysis. The pooled data indicated that the +1580 C/T polymorphism confers a protective effect against NRDS in various populations and ethnic groups. Conversely, the -18 A/C polymorphism did not demonstrate a significant association either globally or among Asian neonates. CONCLUSIONS: The +1580 C/T variant appears to be protective against NRDS, whereas the -18 A/C polymorphism shows minimal impact on the disease's progression.
