MMP Gene Polymorphisms, MMP-1 -1607 1G/2G, -519 A/G, and MMP-12 -82 A/G, and Ischemic Stroke: A 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.
