AIM: To explore the role of rs11053646 polymorphism of oxidized low-density lipoprotein receptor 1 (OLR-1) gene in the susceptibility and prognosis of ischemic stoke (IS). METHODS: A total of 304 IS patients and 377 age and sex-matched healthy controls were recruited. Patients were followed up for 6 months for recovery evaluation of stroke. Genotyping analyses of the rs11053646 G > C polymorphisms of OLR1 gene were performed. RESULTS: The genotype frequencies and alleles frequencies at rs11053646 were significantly differed between stroke subjects and control subjects (both P < 0.001). The presence of CC genotype was significantly higher in IS subjects than in controls (38% vs. 25%, P = 0.001). Similarly, the C allele carriage in IS was significantly higher than controls (59% vs. 49%, P < 0.001). Regression analysis showed the CC homozygote had a significantly increased risk for stroke (adjusted OR = 2.080; P = 0.001). The genotype of rs11053646 were not associated with the IS subtype and severity at admission, but determine the clinical outcome at 6 months after discharge from hospital. CONCLUSION: The rs11053646 polymorphism of OLR1 gene be used as a molecular marker for the susceptibility and prognosis of IS in Chinese population.
