Interestingly, this was not the only immune-related gene implicated in the top probes, with IFI30 (associated with immune regulation and previously implicated in posttraumatic stress disorder; Neylan et al.58) and STAT1 (regulation of immune related signalling; Hu and Ivashkiv59) both showing suggestive results. This evidence concerns the gene IFI30 and post-traumatic stress disorder.
