Objective

To evaluate the association between the angiotensinogen-6 polymorphism (AGT-6) and blood pressure levels.

Design

Data were analysed from the first 4,322 subjects of the NHLBI Family Blood Pressure Program (FBPP), consisting of four networks (GenNet, GENOA, HyperGEN and SAPPHIRe), each conducting a multicentre observational family study to identify and characterize the genetic determinants of hypertension and blood pressure. The four studies use different designs (concordant sibpairs, discordant pairs, sibships, extended pedigrees), target different ethnic groups (Caucasian, African-American, Japanese, Chinese), and have different inclusion/exclusion criteria. However, the protocols and definitions were standardized across networks before data collection to allow maximum poolability.

Methods

Each network/racial group was analysed separately, using generalized linear models that accounted for the non-independence of family members and/or the confounding of anti-hypertensive medications as needed. The results were also pooled using a pre-planned meta-analysis technique.

Results

AGT-6 was not significantly associated with blood pressure in any network/racial group. In the meta-analysis, the pooled effect of AGT-6 was small [hazard ratio = 1.10, 95% confidence interval (CI) = 0.99-1.22, P= 0.0647 for systolic; hazard ratio = 1.04, 95% CI = 0.89-1.21, P= 0.6383 for diastolic]. A post-hoc analysis restricting to subjects meeting JNC VI criteria for Stage I hypertension (blood pressure > 140/90 mmHg or medicated) showed a stronger statistically significant relationship for systolic blood pressure (hazard ratio = 1.44, 95% CI = 1.04-2.00, P= 0.0283).

Conclusions

AGT-6 has minimal to no effect on the inter-individual variation of blood pressure levels, and is at best a 'minor gene' for blood pressure in the population as a whole."xsd:string
