It's called asprosin, it was on the news tonite, but I did a search and found an article from last March, I think. Anyway, it's got to do with glucose and possibly weight gain and loss, and diabetes. The article said it's on the gene B3GALT6. I looked to see if it has been brought up already on PR, and nothing pulled up just like it. Sorry if it's already been discussed and "old hat". Edit: sorry, meant to @Valentijn on this one.
