Title: Single nucleotide polymorphism in the MMP-9 gene is associated with susceptibility to develop multiple sclerosis in an Italian case-control study. Author: La Russa A, Cittadella R, De Marco EV, Valentino P, Andreoli V, Trecroci F, Latorre V, Gambardella A, Quattrone A. Journal: J Neuroimmunol; 2010 Aug 25; 225(1-2):175-9. PubMed ID: 20471697. Abstract: To investigate the role of the matrix metalloproteinase-9 gene (MMP-9) in multiple sclerosis (MS), we analyzed the functional -1562C/T and -90 (CA)(n) repeat polymorphisms in 243 Italian patients with MS and 173 healthy controls. A significant increase of the -1562T allele carriers was found in patients with MS compared to controls. Moreover, haplotype analysis showed that the haplotype formed by the -1562T allele and the L allele ((CA)(<or=20)) was over-represented in patients with MS versus controls. These results suggest that a genetic polymorphism of the MMP-9 promoter region may influence the susceptibility to MS.[Abstract] [Full Text] [Related] [New Search]
