Quarter Horse & Related Breeds Disease Panel (5-panel plus)
This panel bundles together several tests for genetic diseases found in the American Quarter Horse and related breeds.
Panel can be purchased on MyVGL. See below for pricing and list of specific tests included in panel.
Please note: If testing a horse registered or eligible for registration with AQHA, then it is recommended that you order the AQHA's Five-Panel Genetic Disease Test directly through the registry (Order Form). Not doing so may result in a recording fee assessed by AQHA.
Hereditary equine regional dermal asthenia (HERDA) is an inherited skin condition primarily found in Quarter Horses that is characterized by hyperextensible skin, scarring, and severe lesions along the back of affected horses.
Myosin-heavy chain myopathy (MYHM) is a muscle disease in Quarter Horses and related breeds that results in two distinct clinical disease presentations, immune-mediated myositis (IMM) and non-exertional rhabdomyolysis. Both presentations involve muscle loss or damage and are linked to the same genetic variant.
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.
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.
