We don't know exactly when Picard had his DNA stolen to create Shinzon. However, presumably it was some time before Picard was assimilated to become Locutus.
We know that Picard's DNA was altered to turn him into a Borg transmitter or whatever, and that this gave him irumodic syndrome and this went undetected until the Picard show. Strangely enough, none of the medical care he received post-assimilation caught this nor did the transporters (which are said to imprint common human DNA to save power onto all humans, what the changelings sabotaged to infect people with Borg DNA) seemingly overwrite Picard's Borg DNA with the common human DNA template that exists in transporters all the times he was transported after Best of Both Worlds.
Yet if Shinzon was cloned from Picard's original DNA, why didn't Dr. Crusher notice the difference in Shinzon's DNA from Picard's Borg-altered DNA immediately when she compared them? A Starfleet medical computer should catch something like that.
Thoughts?
