OBJECTIVE: To investigate the association between cerebral infarction (CI) and single nucleotide polymorphism (SNP) in the exon of membrane-type 1 matrix metalloproteinase (MMP-14) gene in Chinese Han population. METHODS: Five hundred seventy four patients with CI and 463 healthy individuals were recruited. Serum MMP-14 level was measured with enzyme-linked immunosorbent assay (ELISA). rs1042704 and rs2236307 polymorphisms of the MMP-14 gene were genotyped with a TaqMan assay. Multivariate logistic regression was carried out to analyze the risk factors of CI. RESULTS: A significant lower risk of CI was found in individuals with MMP-14 rs2236307 TC and CC genotypes (vs. TT genotype: P<0.05). The frequencies of MMP-14 rs2236307 C allele were significantly different between the CI group (37.46%) and the control group (43.95%) (P=0.003). Serum level of MMP-14 was higher in the CI group (P=0.003) and was also higher in the group with MMP-14 rs2236307 TT genotype compared with those with CT and CC genotypes (P=0.000; P=0.009). Logistic regression analysis indicated that the MMP-14 rs2236307 CT+CC genotypes was a protective factor, and that history of hypertension, smoking status, triglycerides, diastolic blood pressure and systolic blood pressure were the independent risk factors of CI (AOR:2.027, 1.302, 1.296, 1.434, 2.087; P<0.05). CONCLUSION: The rs2236307 polymorphism of MMP-14 gene is associated with CI, for which the C allele maybe a protective factor. No association of MMP-14 gene rs1042704 polymorphism with CI has been found.
