Although we are unable to specifically confirm a regulatory effect for this locus, or confirm association in the brain, cg19534438 and G0S2 remain an interesting locus for further study in relationship to PTSD based on the strong convergent evidence of association from two independent sources of data and prior studies associating G0S2 expression to PTSD-related traits. This evidence concerns the gene G0S2 and post-traumatic stress disorder.
