Not sure if it's really credible but wikipedia describes it as "leucistic gold." Leucism means that they lack all skin pigmentation, not just melanin(albinism).
I'll try to look further if it's because they altered it or b/c it was natural...
EDIT: No real confirmation but I believe it belongs to the experiment category. Damn, wanted to keep my setup "natural." But I'm keeping my gold
