Horse Color Mushroom
The mushroom gene is a recessive dilution gene that affects red pigment in horses. It was identified in 2014. [1] On a chestnut base coat the horse is born a pale beige with sometimes a greyish or pinkish tint and often keeps that color when it becomes an adult, but some turn darker when an adult.
[2] On a bay base the horse is born a yellowish beige with a dark contrast stripe on the back. Information on the mushroom dilution.Mushroom is one of the dilutions present in horses. Phenotype Mushroom only affects red pigment, and therefore only shows on chestnut- and bay-based horses.

It dilutes the coat to distinctive "sepia" toned coat, often accompanied by a " flaxen" mane and tail. The coat colour can show a wide shade variation and can have similarities to cream and silver. Phenotype: Mushroom is a dilute coat color found in Shetland Ponies that results in a distinctive "sepia" toned coat color, often accompanied by a flaxen mane and tail.
Mode of Inheritance: Autosomal recessive Alleles: N = Normal or non-mushroom, Mu = Mushroom Breeds appropriate for testing: Shetland Pony, Miniature Horse Explanation of. The 4 Base Horse Colors All horses have one of four base colors. Depending on genetics, mutations, parental lineage and coloration, these base colors may skew to some of the more unusual shades or remain mostly or entirely present as the horse's color.

Bay Black Brown Chestnut Rarest Horse Colors Mushroom. Mushroom Dilution Description: Mushroom is a unique recessive coat color type found in the Shetland Pony. In 2019 the researchers using 12 Mushroom colored horses were able to map the phenotype to a frameshift mutation in MFSD12 on equine chromosome 7.
This recessive dilution gene that affects red pigment in horses. Mushroom Breeds Only a few breeds have been identified to carry mushroom, Shetland Ponies are the main breed responsible for the color. Miniature Horses carry it at low frequency.

It's also possible that American Quarter horse, Icelandic horses and Haflingers also carry it, although the Davis genetic testing website doesn't mention them. Mushroom is a unique recessive coat color type found in the Shetland Pony. Horses with two copies of Mushroom dilution are typically described as being a sepia color, and may also have a light or flaxen mane and tail.
In 2019, researchers used 12 Mushroom colored horses to map the phenotype to a frameshift mutation in MFSD12 on equine chromosome 7. The substantial size and bright white coloring of the horse mushroom make it hard to miss. Growing in a grassy green field, it looks like a puffball or white floating orb in the meadow.
Mushroom Dilution Light Black A loose group of unexplained genetics surrounding black coat, skin and eye color variations. Possible undocumented dilution genes. Mushroom Colors The advent of genetic testing for color has given rise to a whole new world of horse color.
While testing indicates that this is a dilution acting on a chestnut coat, its effect on a black is unknown at this time. (Please let me know in the comments below if you know otherwise).
