Informations générales
The Dominant White coat colour pattern in horses can be caused by any in a wide array of related mutations. The resulting pattern can vary anywhere between white markings on the face and legs, up to a completely white coat. Depending on both breed and pattern, variants of the Dominant White phenotype may be referred to as Splashed White, White Spotting, Tobiano or Sabino, among others.
The specific variant analysed in this test, known as Splashed White 2 (SW2), is caused by an incomplete dominant mutation to the paired box 3 (PAX3) gene. It is found in the Lipizzaner horse, Noriker and Quarter Horse breeds and is recently renamed into Auditory-pigmentary syndrome.
Caractéristiques cliniques
SW horses are often characterised by a large broad blaze, white markings on the legs, variable white spotting on the belly and blue eyes.
Additional Information
Coat colour is an intricate trait that involves a combination of multiple different genes. Testing for a range of different loci will give the most complete prediction of a horse's coat colour genetics.
Dominant White can be caused by a wide range of mutations. A white-patterned horse that tests as unaffected for a particular mutation will almost certainly be affected by a different one.
