Objectives: To replicate a previously identified gene-environment interaction between a genetic polymorphism in the serotonin 2A receptor and cultural consonance in family life in relation to depressive symptoms (Dressler et al., 2009).
Methods: A sample of 402 individuals in a sample drawn from four different economic strata in Ribeirão Preto, Brazil was interviewed and genotyped.
Results: Cultural consonance in family life has an inverse association with depressive symptoms (beta = -0.439, P < 0.001) and with high depressive symptoms (OR = 2.36, P < 0.001), but the interaction with genotype was not statistically significant.
Conclusion: The previously identified gene-environment interaction was not replicated. Limitations of the study are discussed. Am. J. Hum. Biol. 28:936-940, 2016. © 2016Wiley Periodicals, Inc.
