DID and epigenetic markers

wow, thank you all, lots of things to check. I myself are not DID, just 2 consistent and aware alters (or substitute identities as I call them). I developed a nasty disease in one of them and then started to research how this is possible, being sick in one identity (a personality is just the expression of the underlying identity) and not in the other (and symptoms disappearing fast with a switch to the more healthy alter. I Found ways to get out of the nasty one, realized what triggered it and assume it's related to some trauma in my youth. (meaning ptsd and DID have the same origin)
But now i believe that this switch (moment or few seconds) holds the key to how our bodymind deals with trauma. It's not a genetic conditions (although one can have genes that make such substitute identity formation more likely), I think it's epigenetic (which is a very broad range of things) and it leaves traces (in rna, methylation, rna editing and what not). There is some research that points at miRNA changes after trauma. The moment of the switch is where the mechanism is most active and thus i am looking for research about that moment. There is fascinating research about cuttlefish masks and that points to mRNA editing, but nothing like that in humans has been published. Anyway, I take all your comments and remarks serious, and will work the in my draft at www.share-shop.nl/identity.pdf, your comments are welcome.
