Association between MCP-1 2518 A>G gene polymorphism and chronic kidney disease

Area of Science:

• Genetics and Molecular Biology
• Nephrology
• Immunology

Background:

• Monocyte chemoattractant protein-1 (MCP-1) plays a role in chronic kidney disease (CKD) pathogenesis.
• The MCP-1 2518 A>G gene polymorphism influences MCP-1 levels and may impact CKD susceptibility.

Purpose of the Study:

• To evaluate the association between the MCP-1 2518 A>G gene polymorphism and the risk of developing CKD.
• To synthesize evidence from existing studies using a meta-analysis approach.

Main Methods:

• A comprehensive search of electronic databases was conducted to identify relevant studies.
• Meta-analysis was performed using fixed-effects or random-effects models to calculate pooled odds ratios (ORs) and 95% confidence intervals (CIs).
• The analysis included a total of 2415 cases and 2011 controls across various populations.

Main Results:

• No significant association was found between the A allele/GG genotype and CKD risk in overall populations, Asians, Caucasians, or Africans.
• Similarly, the AA/AG genotype showed no association with CKD risk across these populations.
• However, the AA genotype was associated with a reduced risk of CKD in Caucasians (OR 0.816, 95% CI 0.703-0.947).
• Conversely, the AG genotype was linked to an increased risk of CKD in Caucasians (OR 1.230, 95% CI 1.042-1.452).
• No significant publication bias was detected.

Conclusions:

• The AA genotype of the MCP-1 2518 A>G polymorphism may confer a protective effect against CKD in Caucasian populations.
• The AG genotype may represent a risk factor for CKD development in Caucasians.
• Further research is warranted to confirm these findings and explore underlying mechanisms.
