General information

The Coat Colour Dun dilution test tests for the genetic status of the TBX3 gene. This gene has three variants (alleles); allele D is dominant over the alleles nd1 and nd2; allele nd1 is dominant over nd2. The dominant allele D results in Dun dilution with primitive markings. Allele nd1 does not dilute the coat colour of the horse, primitive markings are present but the expression is variable. Allele nd2 does not have an effect on the basic colour.

Clinical features

The Dun dilution gene lightens the coat colour of the horse by lightening the body colour, leaving the head, lower legs, mane and tail undiluted. Dun is also typically characterised by “primitive markings”, almost all dun horses possess at least the dorsal stripe, but the presence of the other primitive markings varies. Other common markings may include horizontal striping on the legs, transverse striping across the shoulders, and lighter guard hairs along the edges of a dark mane and tail.
