Abstract
The aim of this study was to investigate whether polymorphisms in the beta(2)-adrenergic receptor gene (5'LC-Arg19Cys, Arg16Gly, Gln27Glu) are associated with hypertension in patients with or without type 2 diabetes and with the blood pressure levels in normotensive sib pairs. The association study included 291 hypertensive patients without type 2 diabetes, 124 hypertensive patients with type 2 diabetes, and 265 healthy control subjects from SWEDEN: In addition, normotensive sib pairs that were discordant for the Arg16Gly (72 pairs) and Gln27Glu (40 pairs) polymorphisms were identified in type 2 diabetes families from FINLAND: Genotyping was performed using polymerase chain reaction-restriction fragment-length polymorphism analysis....

The association study included 291 hypertensive patients without type 2 diabetes, 124 hypertensive patients with type 2 diabetes, and 265 healthy control subjects from SWEDEN: In addition, normotensive sib pairs that were discordant for the Arg16Gly (72 pairs) and Gln27Glu (40 pairs) polymorphisms were identified in type 2 diabetes families from FINLAND: Genotyping was performed using polymerase chain reaction-restriction fragment-length polymorphism analysis. Homozygous carriers of the Arg16 allele had a significantly increased odds ratio (OR) for hypertension in patients with type 2 diabetes (OR 2.14; 95% confidence interval [CI], 1.05 to 4.33), particularly among lean (body mass index<27 kg/m(2)) patients (OR 3.47; 95% CI, 1.06 to 11.33). The Gln27 allele showed a weaker association to hypertension (OR 1.55; 95% CI, 1.00 to 2.41) and was found to be in linkage disequilibrium with the Cys19 allele of the 5'LC-Arg19Cys polymorphism. In the paired-sibling analysis, siblings with at least 1 copy of the Arg16 allele had higher systolic blood pressure (P=0.049), and nondiabetic siblings had a higher body mass index (P=0.026) than siblings homozygous for the Gly16 allele. These results indicate that the Arg16 allele of the beta(2)-adrenergic receptor gene confers an increased risk for hypertension in subjects with type 2 diabetes and is associated with higher blood pressure levels and higher body mass index in sib pairs who are discordant for the polymorphism.
