Polysaccharide Storage Myopathy (PSSM1)

Type 1 Polysaccharide Storage Myopathy is a glycogen storage disease that results in the accumulation of abnormal complex sugars in muscle cells, which can lead to muscle pain, weakness, and reluctance to move.

Androgen Insensitivity Syndrome (AIS)

Five mutations in the androgen receptor gene, located on the X chromosome, are known to result in androgen insensitivity. Androgen insensitivity syndrome causes male horses to be sterile and appear phenotypically female.

Parentage/Genetic Marker Report

This DNA-based parentage test uses microsatellite marker analysis to compare the DNA profile of an offspring to the profiles of possible parents.

Champagne

Champagne is a coat color dilution responsible for diluting both red and black pigment as well as causing pinkish/lavender skin and amber-colored eyes.

Horse Embryo Pre-Implantation Genetic Diagnosis

Pre-implantation genetic diagnosis (PGD) is a procedure used to screen embryos recovered after uterine flush to determine sex and genetic traits through DNA testing prior to implantation in the uterus.

SynchroGait®

SynchroGait® is a diagnostic DNA test for a genetic variant (A) that has a major impact on the gait and coordination of horses. The discovery by researchers in Sweden showed that the mutation “facilitates lateral gaits, ambling and pace, and inhibits the transition from trot or pace to gallop”. The gait A variant has been identified as a major genetic factor for performance in trotting horses and ability to perform the additional “flying pace” in Icelandic horses. 

Tobiano

Tobiano is a white spotting pattern characterized by white on the body that crosses the topline.

Sabino 1

Sabino is a white spotting pattern that is characterized by white markings on legs often accompanied by white ticking or roaning of the midsection and a blaze on the face.

Roan Zygosity Test

Roan is a white patterning coat color trait characterized by intermixed white and colored hairs in the body while the head, lower legs, mane, and tail remain colored.
