Summary
Interleukin-1 receptor antagonist (IL-1ra) gene polymorphism is associated with premature delivery. A higher frequency of the IL-1raA2 allele was observed in preterm newborns compared to adults.
Area of Science:
- Genetics
- Neonatology
- Immunology
Background:
- Interleukin-1 receptor antagonist (IL-1ra) plays a crucial role in inflammatory processes.
- Genetic variations in the IL-1ra gene may influence susceptibility to various conditions, including preterm birth.
Purpose of the Study:
- To investigate the association between IL-1ra gene polymorphism and premature delivery in Israeli newborns.
- To compare IL-1ra allele frequencies in preterm neonates with those in adult volunteers.
Main Methods:
- Genotyping of the IL-1ra gene was performed using PCR amplification of intron 2.
- The study included 95 Israeli preterm newborns and adult volunteers.
- Allele frequencies were compared between the groups.
Main Results:
- The IL-1raA1 allele was predominant in both preterm newborns and adults.
- A significantly higher frequency of the IL-1raA2 allele was found in preterm newborns (19% homozygous) compared to adults (7% homozygous).
- No association was found between the IL-1raA2 allele and severe sepsis in preterm newborns.
Conclusions:
- The IL-1ra genotype may be associated with the incidence of premature delivery.
- Further research is warranted to elucidate the specific mechanisms linking IL-1ra gene variants to preterm birth.
