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.
