The Hairlessness (Discovered in the American Hairless Terrier) variant causes dogs to have little or no hair, and is located in the SGK3 gene.
Hairlessness (Discovered in the Chinese Crested Dog) Linkage test
The Hairlessness (Discovered in the Chinese Crested Dog) variant causes dogs to have little or no hair, and is located in the FOXI3 gene.
Hairlessness (Discovered in the Scottish Deerhound)
The Hairlessness (Discovered in the Scottish Deerhound) variant causes a dog to have little or no hair, and is located in the SGK3 gene.
Harlequin
The Harlequin variant results in a distinctive pattern of spots of color on a white coat background, but only when the merle variant is also present. The Harlequin variant is found in the PSMB7 gene (known as the H locus).
High Altitude Adaptation
The High Altitude Adaptation variant is associated with an adaptation to living at high altitudes. The variant is located in the EPAS1 gene.
Hind Dewclaws (Discovered in Asian breeds)
The Hind Dewclaws (Discovered in Asian breeds) variant may result in the presence of hind dewclaws, which actually have no function! The variant is also known as DC-1, and is located in the LMBR1 gene.
Hind Dewclaws (Discovered in Western breeds)
The Hind Dewclaws (Discovered in Western breeds) variant may result in the presence of hind dewclaws, which actually have no function! The variant is also known as DC-2, and is located in the LMBR1 gene.
Long Hair (Variant 1)
The Long Hair variant causes long hair in dogs and is located in the FGF5 gene.
Mask
The Mask variant causes dark facial hair, mainly over the dog's muzzle, which looks a bit like a mask. The Mask variant is also known as Em and is found in the MC1R gene (known as the E locus).
Merle
The Merle variant causes a patchy coat pattern common in many herding breeds. Each dog's pattern is unique. On a black dog, areas of black and silver will be seen, or on a chocolate dog, areas of brown and beige. It can occur in combination with many other coat patterns, and can cause blue eyes or a fully or partly pink nose. The Merle variant is found in the PMEL gene (known as the M locus).
Piebald
The Piebald variant causes white spotting, patches and/ or a completely white coat. It can also cause blue eyes, pink or "butterfly" nose, pink eye rims, white toenails and pink paw pads. The Piebald variant, also known as "sp" (for spotting), is found in the MITF gene (known as the S locus).
Recessive Black
The Recessive Black variant is a rare cause of black coat color. The Recessive Black variant, also known as the "a" variant, is found in the ASIP gene (known as the A locus).
Recessive Red (Variant 1)
The Recessive Red variant causes only shades of red (phaeomelanin) pigment to be displayed in a dog’s coat, ranging from a deep red, to orange, yellow or even white. The variant is also known as the e variant and is found in the MC1R gene (known as the E locus).
Reduced Shedding
The Reduced Shedding variant is associated with a decreased tendency for a dog to shed hair. The variant is located in the MC5R gene.
Saddle Tan
The Saddle Tan variant is responsible for a red color pattern with a dark-haired saddle over the back. The variant is located in the RALY gene.
Short Legs
The Short Legs variant is associated with short legs due to chondrodysplasia. The variant is an insertion of an FGF4 gene on chromosome 18.
Short Snout (Variant 1)
Short Snout (Variant 1) causes snout shortening, and actually accounts for 36% of the variation seen in dog muzzle length. The variant is found in the SMOC2 gene.
Short Snout (Variant 2)
Short Snout (Variant 2) has been shown to cause shortening of the head and snout. The variant is found in the BMP3 gene.
Short Tail
The Short Tail variant is associated with a naturally short "bobbed" tail. The variant is located in the T-box gene.
Tan Points
The Tan Points variant is responsible for a distinct symmetrical pattern of tan and dark pigment, with tan markings on the eyebrow, cheeks, chest and lower legs. This variant is also required for a saddle tan pattern to occur.
Widow's Peak (Discovered in the Afghan Hound and Saluki)
The Widow's peak (Discovered in the Afghan Hound and Saluki) is also known as the Grizzle variant. It is responsible for a blended effect of light and dark hair, with the lower part of the body appearing lighter than the top. Other names for this variant include Eg and Domino, and it is found in the MC1R gene (known as the E locus), and is a rare trait.
