Coat Colour Oculocutaneous Albinism (OCA4-1)

Oculocutaneous Albinism is a disorder caused by a lack of pigment in the skin, hair and eyes, resulting in a white coat colour and pale eyes, and which can also cause sensitivity to light. This particular variant of the disease, Oculocutaneous Albinism, is caused by a recessive mutation to the gene SLC45A2. It is found in the Lhasa Apso, Pekingese and Pomeranian breeds, as well as in certain mixed-breed dogs. Similar variants of Type IV albinism are found in the Doberman and the Bull Mastiff.
