Objective:
The aim of this meta-analysis was to clarify the role of Matrix metalloproteinase 1 (MMP-1) -1607 1G/2G (rs1799750) polymorphism on the osteoarthritis (OA) risk.
Methods:
Articles were selected by retrieving the Web of Science, Embase and Pubmed. The strength of the association between -1607 1G/2G polymorphism and OA risk was assessed by odds ratios (ORs) with the corresponding 95% confidence interval (CI) for each study.
Results:
No significant association between -1607 1G/2G polymorphism and OA risk was found in all the models overall (2G2G vs 1G1G, OR (95%CI) = 0.69 (0.36-1.32), P = 0.54; 2G2G + 2G1G vs 1G1G, OR (95%CI) = 0.88 (0.47-1.63), P = 0.69; 2G2G vs 2G1G + 1G1G, OR (95%CI) = 1.30 (0.68-2.47), P = 0.41; 2 G vs 1G, OR (95%CI) = 0.90 (0.86-1.54), P = 0.66). By subgroup analysis, significant association was found in the "< 60 years" group (2G2G vs 1G1G, OR (95%CI) = 3.46 (2.13-5.62), P = 0.00; 2G2G + 2G1G vs 1G1G, OR (95%CI) = 0.49 (0.31-0.79), P = 0.00; 2G2G vs 2G1G + 1G1G, OR (95%CI) = 2.74 (1.80-4.16, P = 0.00; 2 G vs 1G, OR (95%CI) = 0.56 (0.35-0.89), P = 0.01).
Conclusions:
This meta-analysis showed that -1607 1G/2G polymorphism may increase the susceptibility to OA among the younger populations (<60 years). More studies with detailed information are needed to validate our conclusion.
Level Of Evidence:
Level I Diagnostic Study.
Insights
The Matrix metalloproteinase 1 (MMP-1) -1607 1G/2G polymorphism does not appear to increase osteoarthritis risk overall. However, this genetic variant may be associated with increased OA susceptibility in individuals younger than 60 years.
Area of Science:
- Genetics
- Rheumatology
- Biochemistry
Background:
- Osteoarthritis (OA) is a prevalent degenerative joint disease.
- Genetic factors play a role in OA pathogenesis.
- The Matrix metalloproteinase 1 (MMP-1) gene, specifically the -1607 1G/2G polymorphism (rs1799750), has been investigated for its association with OA risk.
Purpose of the Study:
- To conduct a meta-analysis to clarify the association between the MMP-1 -1607 1G/2G polymorphism and the risk of developing osteoarthritis.
- To evaluate the overall and subgroup associations of this genetic variant with OA.
Main Methods:
- A systematic literature search was performed across major databases including Web of Science, Embase, and PubMed.
- Studies investigating the MMP-1 -1607 1G/2G polymorphism and OA risk were included.
- Odds ratios (ORs) with 95% confidence intervals (CIs) were used to assess the strength of association.
Main Results:
- Overall, no statistically significant association was found between the MMP-1 -1607 1G/2G polymorphism and osteoarthritis risk across various genetic models.
- Subgroup analysis revealed a significant association in individuals younger than 60 years, suggesting increased OA susceptibility in this demographic.
- Specific ORs and P-values indicated significant findings in younger populations for different genotype comparisons.
Conclusions:
- The MMP-1 -1607 1G/2G polymorphism may be linked to an increased susceptibility to osteoarthritis, particularly in younger individuals (under 60 years).
- Further research with more detailed data is recommended to validate these findings and elucidate the underlying mechanisms.
