Previous studies of cases and controls or selected patients demonstrated association of the ADRB1 Arg389Gly and ADRA2B I/D polymorphisms with blood pressure, measures of obesity, and/or serum lipids. In multivariate-adjusted analyses of 1881 subjects randomly recruited froma White population, ADRB1 ArgArg homozygotes, compared with Gly allele carriers, had higher diastolic blood pressure (79.4 vs 78.4mmHg; P¼0.012), and higher serum high-density lipoprotein (HDL) cholesterol (1.33 vs 1.29mmoll1; P¼0.020), whereas none of the other cardiovascular or metabolic phenotypes reached significance in relation to the two polymorphisms.

Abstract
Previous studies of cases and controls or selected patients demonstrated association of the ADRB1 Arg389Gly and ADRA2B I/D polymorphisms with blood pressure, measures of obesity, and/or serum lipids. In multivariate-adjusted analyses of 1881 subjects randomly recruited froma White population, ADRB1 ArgArg homozygotes, compared with Gly allele carriers, had higher diastolic blood pressure (79.4 vs 78.4mmHg; P¼0.012), and higher serum high-density lipoprotein (HDL) cholesterol (1.33 vs 1.29mmoll1; P¼0.020), whereas none of the other cardiovascular or metabolic phenotypes reached significance in relation to the two polymorphisms. Our family-based design excluded population stratification as a possible explanation for the significant association of the ADRB1 Arg389Gly polymorphism with blood pressure and HDL cholesterol.File | Dimensione | Formato | |
