Background.
It has been widely suggested that analyses considering multilocus effects would be crucial to characterize the relationship between gene variability and essential hypertension (EH).
Objective.
To test for the presence of multilocus effects between/among seven polymorphisms (six genes) on blood pressure-related traits in African-derived semi-isolated Brazilian populations (quilombos).
Methods.
Analyses were carried out using a family-based design in a sample of 652 participants (97 families).
Seven variants were investigated: ACE (rs1799752), AGT (rs669), ADD2 (rs3755351), NOS3 (rs1799983), GNB3 (rs5441 and rs5443), and GRK4 (rs1801058).
Sensitivity analyses were further performed under a case-control design with unrelated participants only.
Results.
None of the investigated variants were associated individually with both systolic and diastolic BP levels (SBP and DBP, respectively) or EH (as a binary outcome).
Multifactor dimensionality reduction-based techniques revealed a marginal association of the combined effect of both GNB3 variants on DBP levels in a family-based design (P=0.040), whereas a putative NOS3-GRK4 interaction also in relation to DBP levels was observed in the case-control design only (P=0.004).
Conclusion.
Our results provide limited support for the hypothesis of multilocus effects between/among the studied variants on blood pressure in quilombos.
Further larger studies are needed to validate our findings.
