Abstract

BACKGROUND Apolipoprotein E (ApoE) is a multifunctional protein that plays an important role in lipoprotein metabolism. However, the relationship between APOE gene polymorphisms and cerebral infarction in the Chinese population remains unclear. Therefore, we studied the role of APOE gene polymorphisms in patients with cerebral infarction in a Chinese population. MATERIAL AND METHODS This study involved 906 patients with cerebral infarction and 1,141 individuals without cerebral infarction who served as controls. APOE genotypes were identified in all participants who participated in the study. Factors influencing cerebral infarction were also analyzed. RESULTS Statistically significant variances in the distribution and frequencies of the APOE genotypes in the patients were observed (ε2/ε3 versus ε2/ε4 versus ε3/ε3=22.85% versus 7.62% versus 56.95%) and controls (ε2/ε3 versus ε2/ε4 versus ε3/ε3=17.27% versus 2.72% versus 66.87%; p<0.001). Univariate analysis showed that the APOE ε3/ε3 genotype [OR, 0.393 (95% CI, 0.237-0.653); p<0.001] and ε3/ε4 genotype [OR, 0.376 (95% CI 0.221-0.637); p<0.001] played a protective role against cerebral infarction in Chinese men. CONCLUSIONS Statistically significant variances in the distribution...Continue Reading
