I think all the Blackrunners are in some way. Mylo has this 'super-genius' talent, and he doesn't understand the purpose of hierarchies, which is a common trait you can see in autistic kids. Blackrunners have their mutations, the things that mark them as different as children... until they grow up. Like how an autistic person might learn to mask it when they get older. And apparently they usually excel in one of the Four over the others.
Nitro admittedly doesn't quite fit into the theory for me but also him having ESP - having psychometry - certainly is something different.
