The C825T polymorphism of GNB3 gene effects the response to 15-days-treatment of adalat / 中国药理学通报

ABSTRACT

AIM To study the relationship between the response of hypertension patients to Adalat and the C825T polymorphism of the GNB3 gene. METHODS 554 hypertension subjects were treated with Adalat. Epidemiological and clinical data were collected. Genotypes of the GNB3 gene were measured by the PCR RFLP method. Linear and logistic regression were used to analyze the association between GNB3 genotypes and the response to Adalat. RESULTS The frequency of the 825T allele in our hypertensive group (48 4%) was slightly higher than that of the normal Chinese reported previously by Siffert W et al. (42%). The average SBP decrease after 15 days of Adalat treatment of subjects with the T allele was significantly less than that of the subjects with the CC genotype (?=-3 3, P= 0 03). Using logistic regression, the subjects with the T allele were less likely to reach good treatment result compared to those with the CC genotype (OR=0 33, P =0 02). CONCLUSION The GNB3 gene C825T polymorphism is related to the response to Adalat.
