Phenotype: The albino mutation produces a white coat with blue eyes.
Mode of Inheritance: Autosomal recessive
Alleles: N = Normal/non-albino, A = Albino
Breeds appropriate for testing: Tonkinese, Siamese, blue-eyed white cats of other breeds
Explanation of Results:
- Cats with N/N genoytpe will not be albino and cannot transmit this albino variant to their offspring.
- Cats with A/N genotype will not be albino, but are carriers. They will transmit this albino variant to 50% of their offspring. Matings between two carriers are predicted to produce 25% albino kittens.
- Cats with A/A genotype will be albino, and will transmit this albino variant to all of their offspring. Matings between two A/A genotype cats are predicted to produce all albino kittens.
Feline albinism is a rare inherited condition characterized by a lack of pigment resulting in cats with a white coat and blue eyes.
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 (c.936delC) causes a shortened form of the TYR protein and produces an albino phenotype of a white coat with blue eyes. The albino mutation is recessive to the Burmese (cb) and Siamese(cs) mutations following the allelic series C>cb=cs>ca.
