Overlap between differentially expressed genes (DEGs) and differentially methylated loci (DMLs) in the amygdala of mice that were exposed to maternal separation (MS) and are offspring of tryptophan hydroxylase 2-deficient (Tph2+/-) parents. For statistical analysis of RNA expression and DNA methylation, contrasts were calculated for Tph2MS interactions GE1 [(Tph2+/- MS-Tph2+/- C)-(Tph2+/+ MS-Tph2+/+ C)] and GE2 [(Tph2-/- MS-Tph2-/- C)-(Tph2+/+ MS-Tph2+/+ C)]. Per group 8 samples (total 48 samples were sequenced for either analysis). For DNA methylation data, pre-analysis quality control revealed two outlier samples, both of the Tph2-/- MS condition, which were excluded from analysis. Genes of either analysis were determined differential if they showed a nominal p < 0.01 and lg2FC > | 0.2|. Fars2, phenylalanine-tRNA synthetase 2 (mitochondrial); Nsun2, NOL1/NOP2/Sun domain family member 2; Cck, cholecystokinin; Xkr4, X-linked Kx blood group related 4; 5830473C10Rik, RIKEN cDNA 5830473C10 gene; Gm10801, predicted gene 10801; A830073O21Rik, RIKEN cDNA A830073O21 gene; Gm26596, predicted gene 26596; Stx1a, syntaxin 1A (brain); Stom, stomatin; Gm13179, predicted gene 13179.
