Gremlin genes

I know not a whole lot is known about gremlins, but while showing some pictures to my boyfriend, I noticed something odd... Every picture of gremlin mice I could find on google was either texel or rex... Coincidence? Does anyone know if its something about the rex and/or texel gene(s) that is related to the gremlin gene/mutation?
Also, any information on gremlins would be helpful, as I cant seem to find much through google.

Mike Chiodo is who you might want to contact about gremlin. You should be able to find some contact info by googling him.

He is also on facebook.
