Could it be used on someone who is a 7 year old to rid them of this?
No. Gene editing works in this case since they’re just working with a few cells. But a whole human is way more cells. Not only that, but the cells have already developed into structures that are much harder to access, and difficult to change. Any gene therapy may only affect a few cells.
On top of that, there’s also a bunch of ethical issues around altering a human when they’ve already formed, and we don’t really know if it would be possible to do so, or if it would make things worse.
