Supporting this idea, a significant upregulation of SLITRK4 was found in the female prefrontal cortices (orbitofrontal cortex and subgenual prefrontal cortex) of patients with PTSD (Girgenti et al., 2021) and the blood of military personnel with PTSD (Guardado et al., 2016). Here, SLITRK4 is linked to post-traumatic stress disorder.
