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.

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.

Lethal White Overo (LWO)

Lethal white overo (LWO) is a genetic disorder that results from two copies of the version of the gene causing the frame overo coat color pattern.

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.

Multiple Congenital Ocular Anomalies (MCOA)

Multiple congenital ocular anomalies (MCOA) is an inherited eye disorder that is associated with the silver dilution and is characterized by ocular cysts, enlargement of the cornea, abnormally formed iris/retina, and additional abnormalities.

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. 

Immune-Mediated Myositis (IMM/MYH1)

Immune-mediated myositis (IMM) is an autoimmune muscle disease that can result in severe atrophy and extreme muscle loss. The genetic susceptibility to this condition is found in quarter horses and quarter horse-related breeds.

Malignant Hyperthermia (MH)

Malignant hyperthermia (MH) is an inherited disease in which affected horses can be triggered by halogenated anesthetics, succinylcholine, stress, or excitement, which can induce a hyper-metabolic state characterized by symptoms including muscle contracture, elevated temperature, and an irregular heart rhythm.
