[The relationship between dyslipemia and the polymorphism of angiotensin II type 1 receptor gene in hypertensive Kazakans of Xinjiang.].

Objective: To investigate the relationship between dyslipidemia and the polymorphism of angiotensin II type 1 receptor (AT(1)R) gene A1166C in hypertensive Kazakans of Xinjiang area.

Methods: Polymerase chain reaction and restriction fragment length polymorphism (PCR-RFLP) methods were used to detect the A1166C polymorphism of AT(1)R gene of 296 hypertensive and 198 normotensive Kazakans. Biochemical parameters were measured by autochemical emalyzer.

Results: (1) The TC and LDL-C levels are significantly higher in hypertension group than those in normotensive controls [TC: (4.91 +/- 1.19) mmol/L vs. (4.43 +/- 1.20) mmol/L; LDL-C: (3.36 +/- 1.01) mmol/L vs. (2.94 +/- 1.30) mmol/L, P < 0.001). (2) In hypertension group, TC and LDL-C are related to A1166C polymorphism of AT(1)R gene and TC and LDL-C of AC carriers are significantly higher than AA carriers (P < 0.05).

Conclusion: The dyslipidemia is related to A1166C polymorphism of AT(1)R gene in hypertensive Kazakans.
