Abstract

OBJECTIVE: To explore the association between estrogen receptor (ER) gene PvuII and XbaI polymorphisms and cerebral infarction among Chinese Han people. METHODS: Samples of peripheral blood white cell were extracted among 234 patients with cerebral infarction, aged 63.9 +/- 10.3, and 259 controls without cerebrovascular disease, aged 59.2 +/- 9.2, all of Chinese Han nationality. PCR-RFLP and genotyping of ER PvuII and XbaI polymorphisms were performed. Multiple Logistic regression analysis was made to explore the risk factors for cerebral infarction. RESULTS: After adjustment for major confounders including age, gender, smoking, alcohol drinking, education, history of hypertension, diabetes mellitus, coronary artery disease and hyperlipoidemia, multiple Logistic regression analysis showed that: (1) The Pp genotype of ER PvuII polymorphism increased the risk of cerebral infarction significantly (OR = 1.97, 95% CI: 1.21 - 3.21); (2) The ER XbaI polymorphism was not in association with cerebral infarction significantly; (3) The PPXx/Ppxx genotypes increased the risk of cerebral infarction significantly (OR = 1.67, 2.52 and 2.18 respectively, P < 0.05) before or after all subjects were stratified by the history of hypertension or hyperlipoidemia; and (4) The positive interaction between the ER PvuII polymorphism and the presence of hypertension or diabetes or hyperlipoidemia could increase the risk of cerebral infarction significantly. CONCLUSION: ER gene may be one of the genetic candidate genes for cerebral infarction among Chinese Han population.
