This is a pretty amazing development.
Girl had cancerous T-Cells meaning her immune system was the problem, so they modified healthy cells to attack all unmodified T-Cells and can now replace them via bone marrow transplant having cleared out her own.
Sounds like this latter stage hasn't been completed yet so a bit early for celebration, but probably the coolest DNA manipulation I've seen in the news for a while.

Certainly a league beyond gene swapping.
'Base editing allows scientists to zoom to a precise part of the genetic code and then alter the molecular structure of just one base, converting it into another and changing the genetic instructions.' 'Sickle-cell anaemia, for example, is caused by just one base change that could be corrected.'
What I'm not clear about is whether they change a base pair, or just one of the pair. It seems to imply one, but then it wouldn't fit with the other one. A-T and C-G are specific pairs; you can't have A-C, G-T etc.
