abstract="DNA methylation profiles of aggressive behavior may capture lifetime cumulative effects of genetic, stochastic, and environmental influences associated with  aggression. Here, we report the first large meta-analysis of epigenome-wide  association studies (EWAS) of aggressive behavior (N = 15,324 participants). In  peripheral blood samples of 14,434 participants from 18 cohorts with mean ages  ranging from 7 to 68 years, 13 methylation sites were significantly associated with  aggression (alpha = 1.2 × 10(-7); Bonferroni correction). In cord blood samples of  2425 children from five cohorts with aggression assessed at mean ages ranging from 4  to 7 years, 83% of these sites showed the same direction of association with  childhood aggression (r = 0.74, p = 0.006) but no epigenome-wide significant sites  were found. Top-sites (48 at a false discovery rate of 5% in the peripheral blood  meta-analysis or in a combined meta-analysis of peripheral blood and cord blood)  have been associated with chemical exposures, smoking, cognition, metabolic traits,  and genetic variation (mQTLs). Three genes whose expression levels were associated  with top-sites were previously linked to schizophrenia and general risk tolerance. At six CpGs, DNA methylation variation in blood mirrors variation in the brain. On  average 44% (range = 3-82%) of the aggression-methylation association was explained  by current and former smoking and BMI. These findings point at loci that are  sensitive to chemical exposures with potential implications for neuronal functions. We hope these results to be a starting point for studies leading to applications as  peripheral biomarkers and to reveal causal relationships with aggression and related  traits.<p /> <p>Language: en</p>",
