About the Colour
The Colour gene (Tyrosinase, TYR) has four alleles (C, cs,cb and c). The wild-type allele (C) is dominant and produces full colouration. The cs and cb mutations cause temperature sensitive pigment production that is characteristic of Siamese colourpoint and Burmese colouration, respectively. The c allele is rare and causes full albino colour.
Two copies of the Burmese allele (cb) are required for Burmese colouration and cause a change from black to sepia and orange to yellow, with the points being darker than the body.

Bengal and Savannah cats - our domestic cat Burmese colour genetic test has also been validated in Bengal and Savannah cats (i.e. it will detect Asian Leopard Cat or Serval genes if they are present).
Interpretation of results
Test Result |
Interpretation |
Burmese colouration (cb/cb) |
Has two copies of the Burmese colouration allele (cb/cb). Cat will have Burmese colouration. |
Carrier of Burmese colouration (C/cb or cs /cb) |
Has one copy of the Burmese colouration allele. Cat will have solid colouration (C/cb) or be Mink (seebelow) if it also carries Siamese colourpoint (cs/cb). |
Does not carry Burmese colouration (C/C or C/cs or cs/cs) |
Has no copies of the Burmese colouration allele. Cat will have solid colouration (C/C, C/cs) or be Siamese colourpoint (cs/cs). |
Mink colouration
Mink colouration is intermediate between Siamese and Burmese and is caused by the presence of one Siamese allele (cs) and one Burmese allele (cb). If you wish to test for Mink please select
both the Siamese and Burmese colouration tests
Snow colour - Bengals
There are 3 kinds of Snow Bengal - Lynx, Sepia and Mink.
- Snow Lynx is caused by the Siamese colourpoint mutation.
- Snow Sepia is caused by the Burmese colour mutation.
- Snow Mink is caused by a combination of Siamese and Burmese
mutations.
Hence, to check the kind of Snow Bengal you have you need to request Siamese and Burmese colour tests.
