The relapsing-remitting-MS (RRMS) is the most common form of this disease. Matrix metalloproteinase-7 (MMP-7) is an important member of the MMP family, which degrades many extracellular matrix components. The common polymorphism of MMP-7 A-181G is associated with some diseases. Objectives: The aim of the present study was to determine the influence of this polymorphism on the risk of RR-MS.
