[Association between the regulator of G-protein signaling 2 gene 1891-1892del TC polymorphism with hypertension in Xinjiang Kazakh population].
OBJECTIVE
To investigate the association of the 1891-1892del TC polymorphism of regulator of G-protein signalling 2 (RGS2) gene with hypertension in Xinjiang Kazakh population.


METHODS
The case-control study was performed in 444 cases and 489 controls. The genotypes of the individuals in the 1891-1892del TC locus were identified by TaqMan method.


RESULTS
A significant association was observed between the1891-1892TC insertion/deletion polymorphism with hypertension in men (OR=1.698, P=0.03) and in the total population (OR=1.32, P=0.044). The mean systolic blood pressure and serum uric acid levels of the ID+DD carriers were significantly higher than that of the II carriers (adjusted, P=0.04 and P<0.01).


CONCLUSIONS
The results suggest that the D allele of the 1891-1892TC insertion/deletion locus of the RGS2 gene might be an independent risk factor for hypertension in Xinjiang Kazakhs; and the polymorphism may have some influence on serum uric acid level in this population.
