I thought he described that person as the light in the darkness or something. I'm not doubting the 'pure blood' thing, I just don't remember it.

Not necessarily. He he could have gotten his shot after she was conceived. Angela may be pure blood, Peter may be pure blood, Merridith may be pure blood. Do we know when these shots are administered? Do we know that the children of synths get powers on their own? It's possible her powers come from Angela's side of the family.
Also, if Angela, Arthur, Peter & Sylar are all naturals and not synths, then couldn't the gene just skip a generation? Or the manifestation skip a generation? I don't know anything about genetics, but it's an idea.
EDIT: Okay a quick google search showed up something along the lines of 'there is one hope among you who carries the purity of blood, who carries the “light” to safeguard against the darkness'. So yeah it did happen. What I don't know if the purity of blood is metaphorical for somebody who is good, rather than someone whose ability isn't synthetic.
