Exposure to maternal [Spearman’s rank correlation coefficient (ρ)=−0.06, p = 0.10] or paternal ASP symptoms (ρ=−0.3, p = 0.55) was not associated with daughter’s MAOA genotype. Females with low/low genotype had increased exposure to childhood adversity, although differences were non-significant. In a test of evocative rGE, MAOA genotype did not predict exposure to childhood adversity using a linear regression approach (β = 1.8, p = 0.24), suggesting that MAOA genotype does not affect exposure to childhood adversity.
