I hope I am not being a "noob" in asking this, but is Wiccan considered a mutant. Assuming that the Scarlet Witch is his mother. Even if she is his mother they are not genetically related so would he have the x-gene? Is it possible to have mutant powers and not be a mutant? Needless to say I am confused.

I think he is considered a mutant...

He's never been called or referred to as a mutant. Neither has his "brother" Speed.

There is no real evidence one way or the other. He and Speed's powers could be magical in nature or genetic. There is no reason to assume that he isn't a mutant. Beast, Angel, Jean Grey, and Cyclops all had flatscan parents, so its perfectly possible. But then again Wanda Maximoff's reality altering powers may just have given them powers, or her powers may have just made them mutants, after all she can remove mutant powers so logically she could probably bestow them. Wanda's near infinite plot-device powers allow for either option. I think I remember the kids just assuming they were mutants in the young avengers series until the vision told them about the Scarlet Witch's involvement.
Then again, (SPOILER ALERT) Doom did remove/suppress his powers using magic which implies they are magical in nature. Basically it doesn't matter to anyone except the X-men.

It's neither been confirmed nor denied whether or not Wiccan and Speed are mutants. It's part of the ongoing "Mystery of the Scarlet Witch" plot. They're going to keep us in the dark as long as they can keep the story going. Hopefully by the end of Children's Crusade we'll finally get a straight answer.

Wasn't it confirmed that he was a mutant when he said that he was part of the X-men in the future in Doctor Strange and the Sorcerers Supreme?
