Abstract: Background: Matrix metalloproteinase 10 (MMP10) plays an important role in ischemic stroke and has a close relationship
with some stroke risk factors. The aim of this study was to investigate the relationship between two single nucleotide polymorphisms
(SNP) in the exon regions of the MMP10 gene and atherothrombotic cerebral infarction risk. Methods: Five hundred and thirty-seven
hospital-based patients who had suffered first atherothrombotic cerebral infarction and 580 unrelated healthy controls were enrolled.
Demographic and clinical features of the subjects were recorded, and two polymorphisms, rs17435959 (G>C), rs17293607 (C>T)
were chosen to be genotyped by real-time polymerase chain reaction-restriction TaqMan probes using the ABI 7300 TaqMan platform.
Results: There were several clinical parameters, such as blood pressure, fasting blood glucose, total cholesterol, homocysteine, as
well as carotid plaque and smoking, but not average age and sex ratios that showed significant differences between patients and
control subjects. For rs17435959, there was no significant difference between the ischemic stroke group and the healthy control group
in genotype frequency (OR=1.295, P=0.187, 95% CI (0.882-1.899)) or allele frequency (OR=1.267, P=0.202, 95% CI (0.881-1.823)).
Moreover, in smoking, none smoking, having carotid plaque, no carotid plaque, male or female subtypes, there was significant
difference between patients and control subjects in genotype frequencies or allele frequencies. The minor allele frequency of
rs17293607 was 0.92%, prohibiting further study of this allele. Conclusions: These findings suggest that the rs17435959 SNP may not
associated with atherothrombotic cerebral infarction risk. We also found that rs17293607 is not polymorphic in our study population.
