We found expression levels of the LRP8 (low density lipoprotein receptor (LDL) receptor related protein 8, or ApoER2) gene, which is highly expressed in the hippocampus and amygdala, and GOLM1 (golgi membrane protein 1) gene to be significantly greater in soldiers reporting symptoms of PTSD. This evidence concerns the gene GOLM1 and post-traumatic stress disorder.
