I wonder what the implications are for everyday stress. I mean, if extreme events can cause enduring anxiety what would even minimal stress do when repeatedly experienced over years do?

I suppose a lot of research is done in this area, but are there anyone looking into whether PTSD and chronic symptoms of repetitive stress have genetic overlaps?

PTSD and traumatic events will need to be studied so much more…but it’s a good start. So what gene is it anyway? How are they testing for this? It will be interesting to see if PTSD is over-diagnosed in a significant number of people simply how they may describe the events…but truly do not exhibit the number of symptoms required to qualify. Is it because insurance covers certain diagnosis and not others? Just some thoughts. Great article though.

Good story, and I appreciate the post, but here to tsk tsk about some sloppiness. Rs25531 is not a gene, it is the designation for a single nucleotide polymorphism. Likewise, 5-httpr is not a gene, it’s the name given to a region of a serotonin transporter gene that is polymorphic. The ‘short’ polymorphism of this region has been linked to anxiety and depression. 5-httpr genotype refers to whether this region has more (long) or less (short) repeats. rs53321 is a SNP, so a single base pair change, in this region.
