[Marvel] Does Xavier's school accept non-mutants?

Okay, so long story short, about two weeks ago I escaped some secret facility, possibly HYDRA's, and I woke up the next day with the ability to shoot lightning from my hands. Now, that's cool and all, but my family doesn't seem to think so. I've been looking for a place to go where I will be accepted, and Charles Xavier's school for gifted youngsters seems like the place to be. However, I heard they're pretty big on mutants there, and I'm pretty sure I'm not one of them. Will I still be able to go there if I'm missing that special X gene? And if not, where can I go?

You can probably still go as you are a mutate and definitely need to learn to control your very deadly powers. Additionally, you may be missing the X gene, but that's not to say that your children (if you ever have any) won't have it. 

Remember, the X-men reached out to spider-man and requested he join when he was transforming into a Man-spider. He too lacked an X-gene. But learning to accept yourself and learning your place in the world is what the school is all about, not specifically the X gene. Having it does, however, help the teachers understand the full nature of your powers and (possibly) if it can be reversed ... if you ever get out of control.

The Prof. has never turned anyone away, but if you feel some other place is better, you might try the military. Particularly SHIELD. They may give you the training needed to improve  and join one of their elite teams or the protection from evil doers who might want to abduct you and turn you into a massive lightening bomb dropped into the middle of NYC killing millions (not that I've thought about it).
