  • Genetic Diagnostic Testing
    We offer testing for known mutations that cause genetic disorders. This can be used to prevent the birth of a foal affected by one of these disorders.

Coat Colour and Pattern Testing

Coat Colour and Pattern Testing

We offer a range of tests designed to detect the genetic mutations that are responsible for certain coat colours and / or patterns. Knowing the genetic status of your horse can be helpful if breeding a particular colour or pattern is a goal. If you are interested in a particular colour test that is not listed below, please notify us of your interest via the 'Contact Us' page.

Tests available

Dominant White W22

W22 is one of the many mutations of the KIT gene that cause the Dominant White phenotype.

Dominant White W10

W10 is one of the many mutations of the KIT gene that cause the Dominant White phenotype.

Dominant White W5

W5 is one of the many mutations of the KIT gene that cause the Dominant White phenotype.

Dominant White W20

W20 is a white booster. It will increase the amount of white on a horse that carries another white spotting pattern.

Splashed White

Splashed white is a white spotting pattern characterised by extensive white markings on the head and legs. Sometimes the white can extend to the body. There are many mutations that cause the SW pattern.

Tobiano

Tobiano is a white spotting pattern consisting of large patches of white that typically cross over the horses topline

Sabino-1

Sabino-1 causes white on the legs, belly and face, which often has roaning around the edges

Appaloosa Pattern-1

Appaloosa Pattern – 1 increases the amount of white in observed in horses that also carry Leopard Complex.

Leopard Complex

Leopard complex causes a number of different spotting patterns

Grey

Grey causes accelerated loss of pigment in the coat which will slowly turn white as the horse ages

Dun

Dun is a coat colour dilution that is often accompanied by primitive markings such as a dorsal stripe or leg barring

Pearl

The pearl mutation dilutes both red and black pigment if two copies are present

Champagne

This mutation dilutes the horses coat whether they carry one or two copies

Silver

Silver dilutes black pigment whilst not affecting red pigment

Cream Dilution

One copy of this mutation will dilute red pigment while two copies dilutes both red and black pigment

Agouti

This gene determines the distribution of black pigment, if it is present

Red Factor

This gene determines whether the horse will have any black pigment in its coat

OLWFS

OLWFS is a fatal disorder of the digestive system that is associated with a particular white pattern called “frame overo”
