Interesting, but as pointed out, we don’t fully understand other cascade effects. For instance, removal of this gene might impact memory suppression. While that can enhance learning, it could also make it more difficult to cope with trauma. It’s a really hard thing to account for. This is a perfect example of genes not being a 1:1 ratio of gene to changes on the body.
I can also understand the “Brave New World” fears that could arise.
I do think it is something with amazing applications potentially, but considering the life spans of people, you’re not going to get a full data set for a very long time.
