MMP Gene Polymorphisms, MMP-1 -1607 1G/2G, -519 A/G, and MMP-12 -82 A/G, and Ischemic Stroke: A Meta-Analysis.
Journal of Stroke and Cerebrovascular Diseases(2018)
Abstract
Several polymorphisms in the human gene encoding MMP have been investigated for the association with ischemic stroke (IS) in the population, of which the MMP-1 -1607 1G/2G, -519 A/G, and MMP-12 -82 A/G polymorphisms gain more and more attention; however, the results are controversial and ambiguous. We therefore carried out the meta-analysis to yield a valid conclusion.The literature database was comprehensively searched to identify potentially eligible reports.A total of 15 studies with 3237 cases and 3075 controls were included in this meta-analysis.There was a significant association in MMP-1 -1607 1G/2G and MMP-12 -82 A/G gene polymorphisms, but none was observed in MMP-1 -519 A/G. When a subgroup analysis by ethnicity and HWE, MMP-12 -82 A/G gene polymorphisms may be a risk factor for IS in Europe. In Africa, MMP-1 -1607 1G/2G and MMP-12 -82 A/G also showed a significant effect on IS. Further investigation on a larger sample size of different ethnic populations is needed to confirm the findings.
