The Correlation of Polymorphisms of AT1R A1166C and AGT M235T Genes and Blood Biochemical Indicators with Essential Hypertension in the Male of Yi Nationality in Yunnan Province

［Abstract］Objective To investigate the correlation of the polymorphisms of angiotensin Ⅱ type 1 receptor （AT1R） gene A1166C and angiotensinogen（AGT）gene M235T and blood biochemical indicators with essential hypertension（EH）in the male of Yi nationality in Yunnan province. Methods 92 hypertensive and 70 normotensive of Yi people were recruited in Yunnan province. Their basic information and blood biochemical indicators were obtained by questionnaire and standardized physical examination. The genes polymorphisms were determined by polymerase chain reaction-restriction fragment length polymorphism（PCR-RFLP）technique. Results（1）For the male EH patients of Yi nationality， 1166C and 235T allele frequencies were 0.038 and 0.772. No significant differences in allele frequency or genotype frequency were observed between the two groups（P > 0.05）. （2）The levels of TC， LDL-C and TG in EH were significantly higher than those in controls（P < 0.05）. Conclusion The AT1R A1166C and AGT M235T polymorphisms were not related to the pathogenesis of EH in the male of Yi people. However， the high levels of TC， TG and LDL-C might be the risk factors of EH.
