Summary
Preeclampsia is linked to the interleukin-10 (IL-10) gene polymorphism at position -1082, particularly in White women. No association was found with tumor necrosis factor-alpha (TNF-alpha) gene polymorphisms.
Area of Science:
- Immunogenetics
- Reproductive Medicine
- Perinatal Health
Background:
- Cytokines play a role in preeclampsia (PE) development.
- Gene polymorphisms can influence cytokine production, potentially impacting PE risk.
Purpose of the Study:
- To investigate the association between PE and specific cytokine gene polymorphisms.
- Examined polymorphisms in tumor necrosis factor-alpha (TNF-alpha), transforming growth factor-beta1 (TGF-beta1), interleukin-10 (IL-10), interleukin-6 (IL-6), and interferon-gamma (IFN-gamma).
Main Methods:
- Genotyping was conducted on women with PE and controls, stratified by ethnicity (White and non-White).
- Statistical analysis included chi-square or Fisher exact tests.
- A meta-analysis was performed for TNF-alpha polymorphisms using current and existing data.
Main Results:
- A significantly lower frequency of the IL-10 -1082-G/G genotype was observed in White women with PE compared to controls (5% vs. 15%, P=0.02).
- No significant association was found for other investigated polymorphisms, including TNF-alpha, even after meta-analysis.
Conclusions:
- The study suggests an association between PE and the IL-10 -1082 polymorphism.
- No association was identified between PE and the TNF-alpha -308 polymorphism.
- Further research is needed to fully evaluate the role of cytokine gene polymorphisms in preeclampsia.
