Possibility of an Illiterate Programer?

/prog/, is it possible for a person to know how to code and program computers before knowing how to read and write in English (or any other natural language)? Is there an example of, maybe, a savant with extraordinary talents in the field, but is, otherwise, social inept?

>>13 I don't mean autistism or Asperger's or even Tourette's. That is something else.

I'm more interested in the savant mind. Has there been one yet that has captured the distilled essence of process, mathematical logic and time/change? And could he/she, with assistance perhaps, sit down at a terminal and control the computer with a non-ambiguous language (a computer programming language) and generate decent output (prove theorems, bla)?
