Methods Genomic DNA was extracted from the blood of essential hypertension group (EH group, n=277) and normal group (NT group, n=247), respectively. The polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) was used to detect genotypes of rs11739136 polymorphism of KCNMB1. The unconditional logistic regression analysis was used to evaluate the risk factors associated with Xinjiang Kazak hypertension. Results The unconditional logistic regression analysis showed that KCNMB1-rs11739136 genotypes, high-density lipoprotein ( HDL), low-density lipoprotein (LDL) and cholesterol were not associated with hypertension, while body mass index (BMI) and triglyceride were risk factors for hypertension. KCNMB-rs11739136 polymorphism existed extensively in Xinjiang Kazakh population (P>0.05). The frequencies of CC, CT, TT genotypes and those of alleles C and T were 74.00%, 23.83%, 2.17%, 85.92%, 14.08% in EH group, respectively. NT and EH groups did not significantly differ (P>0.05). Conclusion The rs11739136 polymorphism of KCNMB1 may not be related to essential hypertension in Xinjiang Kazak population
