Coat Color and/or Type

Dun Dilution

Dun is a coat color dilution characterized by lightening of the coat, with the head, lower legs, mane, and tail undiluted. Oftentimes, dun is also characterized by "primitive markings" such as a dark dorsal stripe, barring of the legs, shoulder stripes, and "cobwebbing" on the forehead.

Dominant White Mutations – W5, W10, W13, W20, and W22

Dominant white is a variable white spotting pattern caused by many different mutations in the KIT gene. The VGL tests for the five most common mutations known as W5, W10, W13, W20, and W22. Homozygosity for W5, W10, W13 or W22 is thought to be non-viable.

Cream

Cream is a dilution that causes the palomino, buckskin, smoky black, cremello, perlino, and smoky cream coat colors.

Camarillo White - W4

Camarillo White is a dominant white coat color characterized by a completely white coat, mane, and tail, and is found exclusively in the Camarillo White Horse.

Appaloosa Pattern-1 (PATN1)

Appaloosa Pattern-1 is a modifier of the leopard complex spotting (LP) and controls the amount of white in the coat pattern.

Agouti (Bay/Black)

The agouti gene controls the distribution of black pigment, and determines whether a horse will have a bay or black base coat color.

Mushroom

Mushroom is a dilute coat color found in Shetland Ponies that results in a distinctive “sepia” toned coat, often accompanied by a flaxen mane and tail.

Leopard Complex & Congenital Stationary Night Blindness

Leopard complex or appaloosa spotting is a white pattern in horses characterized by a variable amounts of white in the coat with or without pigmented leopard spots. Horses homozygous for this variant have an ocular condition known as congenital stationary night blindness.
