Combo package for the two base colors of horse coat coloring (Agouti, Extension).

MIM - 6 Variant is the new name for the test that was previously offered as the PSSM2 test. The adaptation reflects the current findings in the field of exertional myopathies. The tests comprises the 6 gene variants ((P2, P3, P4, P8, Px,K1) that are important genetic predispositions for the development of MIM (Muscle Integrity Myopathy), a specific form of exertional...

The Agouti gene (A) is involved with the production of both red (pheomelanin) and black (eumelanin) pigments. It regulates the relative amounts of each pigment produced in melanocytes (pigment-producing cells) in different regions of the horse’s body. A functional version (AA or Ae) results in a horse that has a base color of bay with black mane, tail, legs and ear tips. Two...

The Cream mutation dilutes the red pigment (phaeomelanin) in the hair. It is incomplete dominant: one copy of the cream dilution (n/Cr) results in Palomino and Buckskin coat colors; Smoky Black (black carrying cream) horses look the same as normal black. With two copies of the Cream variant (Cr/Cr), the dilution effect is complete, giving the Cremello, Perlino, and Smoky...

Dun is the original coat color of all horses (wild-type). Over time, two mutations (nd1 and nd2) caused the now wide-spread undiluted phenotypes most modern horses display. Horses with one or two copies of this variant (D/D, D/nd1, D/nd2) are Dun and show the diluted coat color and the primitive markings (zebra stripes, dorsal stripe) on their legs and back. A dun horse must...

Horses with two copies of the MC1R variant (ee) are chestnut (red, sorrel) in color. Horses with only one copy of this variant (Ee) are bay or black-based (depending upon their variants at the Agouti locus), but carry chestnut. A horse that does not carry the variant (EE) cannot have a chestnut foal, even if bred to a chestnut horse.

Frame Overo is a white spotting pattern most common in Quarter Horses, Paint Horses, and specific American Saddlebred and Throroughbred and Warmblood lines. Frame has a great phenotypic variablity; horses with the frame mutation may show the “typical” pattern, or no white at all. For this reason, all horses that may carry frame should be tested before breeding, even if they...

The test detects the mutation in the STX17 gene (a 4.6 kb intronic duplication) which is causative for the Grey coat color. It is also a risk factor for melanoma. The inheritance is autosomal dominant. Horses with one or two copies of the genetic variant (n/G or G/G) will grey with time. This test detects if a horse has one or two copies of the Grey mutation.

Malignant Hyperthermia is an autosomal dominant mutation where fever, muscle rigidity and respiratory distress and even death can be triggered by specific anaesthetics or other stress/exercise. It also worsens the symptoms of horses with PSSM1 and 2.

The KIT Noriker roan allele has been found in Noriker, Lipizzan, Quarter Horse, Murgese and some draft breeds. It is not the classical roan mutation found in most roan quarter horses, but it has not yet been tested in a wide variety of breeds.

PSSM1 is a form of exercise intolerance in which a disorder of the sugar metabolism of the muscles causes muscle damage.
The test detects the mutation (c.926G>A) in the GYS1 gene which causes PSSM1. The inheritance is incomplete autosomal dominant. Horses with one or two copies of the genetic variant (n/P1 or P1/P1) are at risk to develop symptoms of PSSM1; those with two...

Height in animals depends on multiple factors including genes and the environment. One genetic variant (a single basepair change in the LCORL-regulatory region) has a strong influence on height in warmblood horses. This test enables breeders to predict a horse’s adult height before they are fully grown (accuracy: 70% ; +/- 5 cm) and to plan breedings to select for taller or...
