These guys... These fucking guys are bugging me to no end. On a terminal on Prydwen it states that the strains are different from the ones in the Capital Wasteland, in the basement of the Institute through the Bio lab there's a secret laboratory where they've been experimenting on them, apparently Virgil is one of these muties as well or something and he made a cure. Obviously the Institute made them, that's not what's bugging me, it's the why. With Father (Shaun, player's son, director of the Institute) so much against altering scientists with the same kind of enhancements they gave Kellogg (found on his private terminal iirc), why would he allow such experimentation? The terminals there reveal that the scientists themselves aren't sure why the research continues as it doesn't see much progress, and with Virgil's cure there are a few more questions, such as the far-fetched "are they actually trying to cure them?" but that seems more like guessing than anything, especially doubtful considering the massive tanks with mutants submerged into (very likely) liquid FEV. So, digression aside, why did they do it?
