Feline Albino Test

Note: The albino mutation is very rare in cats. Among 9229 cats tested by the VGL, only 4 (2 Tonkinese and 2 Siamese) were positive for this mutation. Because of its rarity, Albino has been removed from the coat color panel testing but will continue to be offered as a stand-alone test. If the genetic basis of a blue-eyed white cat is unknown to owners, we recommend first testing for Dominant White and White Spotting, before requesting the Albino test.


Two mutations in the Tyrosinase (TYR) gene produce the Burmese (sepia), Siamese and mink colorpoint coat and eye color phenotypes in cats. A rare mutation in TYR produces an albino phenotype of a white coat with blue eyes. The albino mutation is recessive to the sepia and Siamese mutations. The VGL offers a test for this albino mutation.

Procedure for collecting a feline DNA sample

Allow 2-6 business days for results.

Results reported as:

N/N:   No copies of albino allele are present.

A/N:   1 copy of the albino allele is present

A/A:    2 copies of the albino allele are present. Cat is albino.
