Abstract: A possible participation of the renin-angiotensin system (RAS) components with mood disturbances has been suggested in both animal and pharmacological models. in this cross-sectional study, we examined the association between functional polymorphisms in the angiotensin converting enzyme (ACE) and angiotensinogen (AGI) genes in 115 bipolar affective disorder (BPAD) patients and 323 healthy control subjects. the ACE I/D variant did not show any difference in allelic frequencies and genotypic distribution between the groups. in contrast, when studying the AGT M235T polymorphism we found that the M allele was more frequently observed in BPAD patients than in controls (chi (2) = 6.766, d.f. = 1, P = 0.009). Using multivariate logistic models the strongest odds ratio resulted from a dominant genetic model (OR = 3.0; CI (95%) 1.7-5.3] Our data suggest an association between the AGT M235 genotype and increased susceptibility for BPAD in these Brazilian patients. These findings are consistent with the hypothesis that the RAS system plays a role in regulating the mood (C) 2000 Published by Elsevier Science Ireland Ltd.
