| Summary |
Here, we selected >1000 variants from over 30 depression-associated loci using brain epigenomic data, and functionally assayed them using in vivo functional assays in the mouse brain to examine sex-by-genotype interactions. We identify extensive sex-by-allele effects in mature hippocampus, suggesting genetic risk and thus disease mechanisms may be distinct between the sexes. Unbiased informatics approaches indicated a role for nuclear hormone receptors, which was supported by . Further, comparative analysis of allelic function in the neonatal mouse brain, during a key between developmental neonates during the masculinizing testosterone surge, and in the adult hippocampus—a region of interest in depression pathology—but not at 10 days old, a older hormonally quiescent developmental stage juveniles. Our study provides novel insights into depression genetics as influenced by age, biological sex, and cell type, and provides a framework for in vivo parallel assays at a scale not previously shown possible to functionally define interactions between sex and disease variation.

| Overall design |
AAV9 MPRA library was delivered into the mouse brain in utero (embryonic day 15). Mice were screened at birth for reporter-driven red fluorescence (visible through the skull by eye by green light illumination). Brains were collected WITHOUT cerebellum for RNA extraction at postnatal day 0 (P0) (n=9 male, n=6 female) or P10 (n=7 male, 6 female).
