is the condition hereditary or just plain random?
It has been confirmed as a Sampson Fox. Less than 1 of the fox population has this condition. The article said that this condition was similar to the albino aligators. Not very many happen in nature, but a few do. The condition causes there to be little or no guard hair on the animal, giving it the appearance of being completely hairless.
