ABSTRACT
Objective: To investigate β2 adrenergic receptor (β2-AR) gene polymorphism, Arg16Gly, Gln27Glu and essential hypertension (EH) occurrence in Tibetan population living at high altitude area. Methods: Our research included in 2 groups: EH group, n=385 patients and Control group,n=297 normal healthy subjects. β2-AR polymorphisms of Arg16Gly and Gln27Glu were detected by Snapshot mini-sequencing technique and their frequencies were compared between 2 groups and male, female genders. Results: The genotype and allele frequency distributions of Arg16Gly and Gln27G1u were similar between 2 groups, P>0.05; there were no signiifcant differences between male and female genders,P>0.05. Conclusion: No obvious relationship was found between β2-AR gene polymorphism (Arg16Gly, Gln27Glu) and EH occurrence in Tibetan population living at high altitude area.
