Test Overview:

Variants of the TYRP1 gene at the brown (B) Locus impact canine coat color by disrupting regular eumelanin (black pigment) synthesis which causes the dilution of black pigmented areas to brown. The B locus also controls the colour of the dog’s nose and foot pads regardless of the dog’s genotype at the E locus because eumelanin is still produced in the epidermis of the nose and foot pads of e/e dogs. Although black is dominant to brown, the overall B locus genotype for a dog is determined by the combination of the genotypes at the bc, bd and bs loci. The bc, bd, and bs variants confer brown coat, nose, and foot pads when at least one of these DNA changes is present on both genes of the dog at the B locus. If the dog has one or no copies of b then the dog will have a black coat, nose, and foot pads. However, the dog’s coat colour is also dependent on the E, K, and A genes among others.
