The MR is an important regulator of the hypothalamic-pituitary-adrenal (HPA) axis and a prime target for corticosteroids. There is increasing evidence from both clinical and preclinical studies that the MR has different effects on behavior and mood in males and females. To investigate the hypothesis that the MR sex-dependently influences the relation between childhood maltreatment and depression, we investigated three common and functional MR haplotypes (GA, CA, and CG haplotype, based on rs5522 and rs2070951) in a population-based cohort (N=665) and an independent clinical cohort from the Netherlands Study of Depression and Anxiety (NESDA) (N=1639). The CA haplotype sex-dependently moderated the relation between childhood maltreatment and depressive symptoms both in the population-based sample (sex x maltreatment x haplotype: beta=-4.07, P=0.029) and in the clinical sample (sex x maltreatment x haplotype, beta=-2.40, P=0.011). Specifically, female individuals in the population-based sample were protected (beta = -4.58, P=2.0e(-5)), whereas males in the clinical sample were at increased risk (beta=2.54, P=0.0022). In line with these results, female GA haplotype carriers displayed increased vulnerability in the population-based sample (beta=4.58, P=7.5e(-5)) whereas male CG-carriers showed increased resilience in the clinical sample (beta=-2.71, P=0.016). Consistently, we found a decreased lifetime MDD risk for male GA haplotype carriers following childhood maltreatment but an increased risk for male CA haplotype carriers in the clinical sample. In both samples, sex-dependent effects were observed for GA-GA diplotype carriers. In summary, sex plays an important role in determining whether functional genetic variation in MR is beneficial or detrimental, with an apparent female advantage for the CA haplotype but male advantage for the GA and CG haplotype. These sex-dependent effects of MR on depression susceptibility following childhood maltreatment are relevant in light of the increased prevalence of mood disorders in women and point to a sex-specific role of MR in the etiology of depression following childhood maltreatment.
