Background: Variation in the corticotropin-releasing hormone receptor (CRHR1) gene has been shown to interact with early life stress to predict adult depression. This study was conducted to determine whether CRHR1 polymorphisms interact with childhood maltreatment to predict hypothalamic-pituitary-adrenal (HPA) axis reactivity, which has been linked to both depression and early life stress. Methods: One hundred twenty-nine White, non-Hispanic adults completed the Childhood Trauma Questionnaire and the dexamethasone/corticotropin-releasing hormone (DEX/CRH) test, and provided blood samples for genotyping of two CRHR1 polymorphisms. Results: Both rs110402 and rs242924 (which were in tight linkage disequilibrium, D' = .98) showed a significant interaction with maltreatment in the prediction of cortisol response to the DEX/CRH test (p
