Russia fears genotyped bioweapons?

I think this is probably a front-runner for the “massive knee-jerk technophobic reaction by a major nation’s goverment” award for this week; there are reports that Russia has suspended the export of human tissue samples for fear that genetic material could be used to make biological weapons tuned specially to attack people with Russian DNA. Now, I’m not a genetic scientist (nor do I play one on television), but while it strikes me that such a thing is probably possible, it certainly doesn’t strike me as being very likely. But who knows? Maybe the new Mutually Assured Destruction scenarios will be based on biological weapons, not nuclear.
