Sheer probability says there has been. There's been dozens upon dozens upon dozens of billions of people that have been born over the course of our species history, so somewhere along the line at least one person has to have been born with that mutation at some point, probably more than one. There's even a good chance there's one alive now actually.

I can feel my brain as it does certain things, for example thinking invokes a similar feeling in my forehead as moving a muscle during exercise does. Not claiming I am a superman though, since it is purely sensorial. I thought everyone was like this and then learnt it wasnt the case.
