There was evidence of non-significant group × sex interaction effects on differential expression of TNFRSF14 (BA11: p = 0.063; BA25: p = 0.15) and TSPOAP1 (BA11: p = 0.055; BA25: p = 0.12), resulting in subsequent sex-specific investigations of differential expression of these genes in PTSD vs. controls. This evidence concerns the gene TSPOAP1 and post-traumatic stress disorder.
