Health and disease risk

Ancestry & Composition Panel*

Androgen Insensitivity (ais) *

Androgen Insensitivity Syndrome (AIS), previously known as Testicular Feminization Syndrome, is a disorder of sexual development in which a horse with a XY SRY+ karyotype appears female.

Anhidrosis (ANH) NEW!

Cerebellar Abiotrophy (ca)

Cerebellar Abiotrophy (CA) is a degenerative neurological disorder due to the death of large neurons (Purkinje cells) in the cerebellum.

Dwarfism (Friesian and acan)

Dwarfism is characterized by abnormal growth, leading to either a disproportionate body type or overall smaller body size.

Equine Metabolic Syndrome (EMS)

Equine Metabolic Syndrome (EMS) is a wide-spread issue in the horse population.

Equine Recurrent Uveitis (ERU)

Equine Recurrent Uveitis (ERU) is the most common cause of blindness in horses.

Foal Immunodeficiency Syndrome (fis)

Foal immunodeficiency syndrome (FIS) is a failure in the development of the adaptive immune system.

Fragile Foal Syndrome (ffs or wffs)

Warmblood fragile foal syndrome is a connective tissue disorder resulting in joint laxity and extremely thin skin that is only loosely connected to the body.

Glycogen Branching Enzyme (gbed)

Glycogen branching enzyme deficiency is a lethal recessive disorder characterized by seizures, muscle weakness, respiratory failure, and death.

Hereditary Equine Regional Dermal Asthenia (herda)

Hereditary equine regional dermal asthenia (HERDA) is a degenerative skin disease that primarily affects the American Quarter Horse breed.

Hoof Wall Separation Disease (hwsd)

Hoof wall separation disease is characterized by separation and breakage of the dorsal hoof wall extending up from the sole.

Hydrocephalus (hyd)

Hydrocephalus is an abnormal build up of cerebral spinal fluid around the brain. In the Friesian, it is believed that a narrowing of a passage within the brain prevents normal fluid absorption, leading to an obvious external cranial distension.

Hyperkalemic Periodic Paralysis (HYPP)

Hyperkalemic Periodic Paralysis (HYPP) is a dominant genetic disorder resulting from defects in sodium channels in the muscle.

ImmuneNoMediated Myositis (IMM)

Immune-mediated myositis (IMM) is an autoimmune disease which, when triggered by an infection, or certain vaccinations (i.e. influenza) can cause severe muscle loss (atrophy) within a period of 3 days (up to 40% in 72 hours).

Impaired Acrosomal Reaction (iar) *

In normal fertilization, the the head of a sperm binds to the egg and releases the contents of a structure known as the acrosome.

Junctional Epidermolysis Bullosa (jeb1)

Junctional epidermolysis bullosa (JEB), also known as red foot disease or hairless foal syndrome, results in the inability to produce the proteins needed to keep the skin on the body.

Junctional Epidermolysis Bullosa (jeb2)

Kissing Spines Susceptibility (KSS)

Laminitis Risk (LAM)

Lavender Foal Syndrome (lfs)

Lavender foal syndrome (LFS), also known as coat color dilution lethal, is a neurological dysfunction in newborn foals.

Lethal White Overo (LWO)

Lordosis (Swayback)

Lordosis, also known as swayback, is a curvature or dip in the spine that is often seen in older horses.

Malignant Hyperthermia (MH)

Malignant hyperthermia (MH) is a muscle disorder in which anaesthesia, stress, or extreme exercise trigger a hypothermic state.

Myotonia (MY)

Myotonia is a rare disorder involving a slowed relaxation of muscles after contraction.

Polysaccharide Storage Myopathy (PSSM1)

Polysaccharide Storage Myopathy (PSSM) is a glycogen storage disorder in which affected horses have chronic episodes of exertional rhabdomyolysis (“tying-up”).

Recurrent Laryngeal Neuropathy (RLN) Roaring

Severe Combined Immunodeficiency (scid)

Severe combined immunodeficiency disease is a condition in which the foal has essentially no immune system, due to a complete absence of certain types of immune cells, specifically B and T lymphocytes.

Squamous Cell Carcinoma Risk (SCC)

Squamous Cell Carcinoma is the most common cause of eye cancer in horses. It is also responsible for a large percentage of tumors throughout other parts of the equine body.

West Nile Virus Risk (WNVR)*

West Nile virus is a mosquito-borne virus that can infect multiple types of mammals, including horses.
