Genetic Diagnostic Testing

Disease Testing

We offer testing for established genetic mutations that cause, or are associated with, disorders in many breeds of horse. Testing can confirm whether your horse is afflicted with a genetic disorder. Testing is also the best way to confirm that your horse does not carry a recessive (hidden) disease DNA variant that it could pass onto its offspring. A list of traits that we test for is displayed below, and is continuously updated with newly developed tests.

Tests available

HERDA is a skin disease found primarily in Quarter Horses and their derivatives.

HYPP is a muscular disorder that causes muscle spasms and tremors.

OLWFS is a fatal disorder of the digestive system that is associated with a particular white pattern called “frame overo”.

PSSM1 causes muscle crampling and tying up.

GBED is a disorder that prevents the storage of glycogen in muscles and other tissues, causing late term abortion, stillbirths and death in affected foals.

MH is a muscle disorder that causes an increased rate of metabolic activity usually associated with administration of certain types of anaesthetic gases.

MYHM (previously called IMM) is a muscle disease found in Quarter Horses.

CA is a neurological disorder that affects coordination and balance.

LFS is a fatal neurological disorder.

SCID is a disorder of the immune system.

OAAM is a bone defect which causes neurological problems.

HWSD is a disease that affects the hoof wall, causing it to easily break and crack.

FFS1 is a disorder of the connective tissue which causes hyperextensible joints and skin tearing in affected foals.

The SCC DNA mutation confers a high risk of squamous cell carcinoma, the most frequently occurring type of ocular cancer in horses.
