Información específica de la prueba
The White Spotting 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 White Spotting phenotype may be referred to as Splashed White, Dominant White, Tobiano or Sabino, among others.
The specific variant analysed in this test, known as White Spotting 15 (W15), is caused by an incomplete dominant mutation to the gene KIT. It has been observed in the Arabian horse.
Características clínicas
Most horses with the W15 mutation have a wide blaze, white socks, and patches of white on the belly and torso. At least two W15/W15 foals have been confirmed by genetic testing, but their health and fertility is unknown; one died of unrelated causes as a foal. They are mainly white with some small roany areas of colour.
Información adicional
El color de la capa es un rasgo intrínseco que implica una combinación de múltiples genes diferentes. Las pruebas para una variedad de loci diferentes darán la predicción más completa de la genética del color del pelaje de un caballo. El blanco dominante puede ser causado por una amplia gama de mutaciones. Un caballo de patrón blanco que es no afectado para una mutación en particular casi seguramente se verá afectado por una diferente.
