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.

Turnaround Time
At least 15 business days; may be delayed beyond 15 business days if sample requires additional testing, or a new sample is requested.

Sample Collection:

Cat DNA tests are carried out using cells collected from your cat's cheeks and gums using household cotton swabs.

The cat DNA submission form with instructions, pricing, and a place to tape the cotton swabs can be printed from your home computer after signing up for a MyVGL account and placing an order. Test kits are not mailed.

Step-By-Step Instructions:

1.

Person looking at different brands of cotton swabs in a storePurchase regular household cotton swabs for cat DNA collection (the cotton swabs can be purchased at a pharmacy or drug store)

 

2.

Label indicating both ends of the two cotton swabsUse both ends of the two cotton swabs for a total of four swabs.

 

3.

Demonstration of swabbing the inner cheek of a cat with a cotton swabCollect the DNA sample by swabbing the cheek and gums of the cat.

 

4.

Cotton swabs taped to bar-coded submission form for VGLAfter swabbing the cheek and gums, tape the cotton swabs to the bar-coded submission form printed from your MyVGL account.

Additional Details

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.

 

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 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.
