I only just discovered about this issue -- thanks to the superlative Sean Croxton.
So I'm listening to the recordings of his Real Food Summit, which are all good, of course, and then his guest Jeffrey Smith starts dropping these bombshells:

First, the Roundup Ready issue:
What! So these people actually ended up with Roundup Ready gut bacteria.The only human feeding trial ever published confirmed that genetic material from Roundup Ready soy transferred into the gut bacteria in three of seven human volunteers.
But it gets worse.
Mr. Smith then starts talking about bt -- Bacillus thuringiensis. U.S. regulators allowed Monsanto to transfer genes from a soil organism into corn. It seems this is another gene that does survive the digestive process, despite claims to contrary. Now bt works because it "... breaks open the stomach of certain insects and kills them".
IOW, it damages the insects' guts. The worry is that it could be poking holes in humans' guts, since the gene survives the digestive process and can transfer into gut bacteria.
Now here's something that should give us pause for thought:
At a Canadian hospital
And:[bt] toxin was identified in 93% of 30 pregnant women [and] 80% of umbilical blood in their babies ...
Here's that link again:The fact that it flows through our blood supply, and that is passes through the placenta into fetuses, may help explain the rise in many disorders in the US since Bt crop varieties were first introduced in 1996
And here's a paper on the matter:

Sean Croxton, summing up, said that what GMOs amounted to was a massive science experiment with totally unpredictible consequences performed on millions of people without their consent.
