The gray allele causes progressive depigmentation of the hair, often resulting in a color that is almost completely white by 6-12 years of age. This test will detect the presence or absence of the gray allele only and is included in the Coat Color Panel. For a more detailed test that determines the specific gray allele(s), please refer to the Gray Copy Number test.
The gray gene causes progressive depigmentation of the hair, often resulting in a color that is almost completely white by 6-12 years of age. This individual gray test will determine the genotype (which alleles and/or number of copies), whereas the coat color panel test that includes gray only detects the presence or absence of the gray alleles.
The extent of shedding is impacted by several genes but two, MC5R and RSPO2, appear to have significant effect on the relative degree of shedding. Combinations of variants identified in these two genes result in decreased overall shedding rates.
Lhasa Apso Albinism (LAA) is an oculocutaneous albinism that is characterized by white or off-white fur and pink skin, and is caused by a missense variant in the SLC45A2 gene. This variant is also responsible for French Bulldog Pink.
Variants in the PMEL17 gene (aka SILV) cause a color dilution from red or black to pale cream or white coat color. This gene has a dosage-dependent effect on pigment, with a single allele diluting black to gray and red to pale red, and a double dose producing a significantly lighter coat.
Includes all tests in the basic cat coat color panel plus a test for the Birman white gloving pattern and the Bengal charcoal coloration. This panel is valid only for the Birman breed and Birman crosses.
