Albino
Albinism in dogs — or any species — isn't a specific breed, but is a rare, genetic mutation known as tyrosinase (full albino) or tyrosinase-positive (partial albino). Albinism causes a complete lack of pigmentation, including of the skin, hair, and eyes as well as the blood vessels, resulting in a pinkish tinge

Intolerance to imperfection does not make the world perfect, it makes the world intolerant.
So, fyi. All cream Dobes are tyrosinase positive. They are all incomplete albinoids at best.The reason it's explained like that, is because there's a difference between Tyrosinase Positive and Negatives. One, still has melanin. The other is the true quintisential Albinoid. No melanin.
A Tyrosinase Positive mammal is nowhere near problematic as a Tyrosinase Negative mammal
Oculocutaneous albinism is the oa gene you test for in z factor dobermans. a z registered dog back be oa clear.
OA is what makes a white doberman. White dobermans have 2 copies, or two standard colored dobermans who are carriers of OA (1 copy) can produce 25% of white dobermans in a litter.

We should educate people about the stipulation that white dobermans are true albinos.
Welll !!! sorry they are not. They are in fact tyrosinase-positive animals, meaning the same thing as a leucistic animal. As far as them not being a standard color through akc they are not. Can they still be akc registered, yes they can. Can you show them, yes but not in the confirmation class. They can be titled in other classes, obedience, agility etc. I'm over the people who can't tell a difference and definitely don't want to learn. But what I can do is educate everyone else who is open minded on the subject.
What Causes Albinism?
A completely pure white animal with pink eyes and pale pink skin is considered albino, and is technically referred to as tyrosinase-negative. Tyrosinase is an enzyme involved in melanin production, and melanin is the natural substance that gives color (or pigment) to the eyes, skin, and hair. Albinism is a lack or defect of this enzyme and is caused by a recessive gene that is inherited from both parents. Many true albino dogs will suffer from deafness because the unpigmented skin in the ear canal causes the nerve endings to degenerate.
Other Forms of Albinism
Other forms of albinism -- referred to as tyrosinase-positive -- result in a dog that exhibits whitening but does have pigment. White German Shepherds, West Highland White Terriers, and White Doberman Pinschers are some of the breeds considered to be tyrosinase-positive. While these dogs may appear to be all white, they are actually either a pale cream or very light gray color.
Definition of leucism
: an abnormal condition of reduced pigmentation affecting various animals (such as birds, mammals, and reptiles) that is marked by overall pale color or patches of reduced coloring and is caused by a genetic mutation which inhibits melanin and other pigments from being deposited in feathers, hair, or skin
How Common Is Albinism?
True albino dogs with no pigment at all are extremely rare. Dogs with some degree of albinism are much more common, especially for the breeds listed above and below.
Did you know know that leucism and tyrosinase positive are the same things?
Did you know what white dobermans have blue 💙 eyes T-pos variant not pink 💟 like a True albino.
Did you know white dobermans can see and hear unlike true albinos.
Did you know white dobermans are only white where their rust markings should be and their body is different shades of cream.
Did you know that tyrosinase-positive dogs come in lots of other breeds beside dobermans.
Let me name some
