    Abstract:
    BACKGROUND: Several studies have reported the association between polymorphisms in Matrix metalloproteinases (MMPs) gene family and risk of Multiple sclerosis (MS). However, the results have been inconsistent and inconclusive. To resolve this issue, here we performed a systematic review and meta-analysis of the MMP-91562 C/T (rs3918242), MMP-3 (- 1612 5A/6A), and MMP-2 (- 1306 C/T) polymorphisms and susceptibility to MS. METHODS: We conducted a comprehensive systematic search in the major electronic database, including Scopus and PubMed to look up for relevant studies published before December 2019 that surveyed the association between the MMP-91562 C/T (rs3918242), MMP-3 (- 1612 5A/6A), and MMP-2 (- 1306 C/T) polymorphisms and susceptibility to MS. The level of association between the polymorphisms and susceptibility to MS in the polled analysis was determined by calculating the odds ratio (OR) and the corresponding 95% confidence interval (CI). RESULTS: We found 15 studies containing 2430 MS subjects and 2304 controls. A statistically significant association was observed in the all five comparisons of the MMP-91562 C/T polymorphism and MS risk as follows: dominant model (OR = 1.62, 95% CI = 1.03-2.53, P = 0.03), recessive model (OR = 2.69, 95% CI = 1.68-4.29, P < 0.001), allelic model (OR = 1.51, 95% CI = 1-2.28, P = 0.04), TT vs. CC model (OR = 3.20, 95% CI = 1.87-5.46, P < 0.001), and CT vs. CC model (OR = 1.53, 95% CI = 1.02-2.28, P = 0.04). CONCLUSIONS: Our meta-analysis revealed significant association of MMP-9 (- 1562 C/T) Single-nucleotide polymorphism (SNP) with MS susceptibility that increased the disease risk.
