Objective: The objective of the current study was to investigate the correlation between polymorphisms in extracellular matrix-degrading enzymes and the risk of intervertebral disc degeneration (IDD) diseases.
Methods: The databases PubMed, Embase, and Cochrane Database were systematically queried from the inception until March 2023 to ascertain studies that meet the eligibility criteria. Utilizing a standardized data collection form to extract data from individual studies. The data were quantified using odds ratio (OR) along with its corresponding 95% confidence interval (95% CI), following an allelic model of inheritance.
Results: The study included a total of nine studies and indicated that the presence of rs17576 in the MMP9 gene was significantly associated with an increased risk of IDD diseases (GG: 1.30, 95% CI [1.09-1.55], p = 0.004). The presence of other polymorphisms in extracellular matrix-degrading enzymes did not exhibit a significant association with the susceptibility to IDD.
Conclusion: The current study demonstrated a noteworthy correlation between the GG genotype of MMP-9 rs17576 and susceptibility to IDD. The available evidence is insufficient to substantiate the correlation between other extracellular matrix-degrading enzymes and susceptibility to IDD. The constraints of this analysis necessitate further research involving larger sample sizes across diverse ethnicities to provide a comprehensive understanding of the true impact of these polymorphisms on susceptibility to IDD.
