I think that the gold dust is a patterened animal but that the Gold dust Spider is almost patternless, We'll see as it ages.

Other things Like the
Genetic stripe are near patternless
Cinni and Pewter and Sterling G-Stripe are patternless
Silver Bullet
Silver Streak
Super Cinni/BP

I'm sure there are some I'm missing but I've got a headache so I can't think.
