This is not a gene mutation. This poor dear spent a great deal of its life wrapped up in a milk ring or some other, probably plastic, man made piece of trash. There are much worse cases (scroll down a bit).
Also, this animal is a red-eared slider, which is called a "turtle" in these parts. Your parts may vary.

I feel so sorry for them and I'm amazed they can live like this. I suppose many don't survive.
