About the Test The PSSM1 DNA test verifies the presence of the affected allele at the GYS1 locus responsible for Polysaccharide Storage Myopathy Type 1 (PSSM1). Sample Collection Hair Roots: 20 to 30 hair roots. Pull the hair and tape it onto the printable sample submission form. Blood Sample: 5 mL blood in a K3 EDTA tube. Collect the blood and send the tube together with the printable sample submission form. Turnaround Time Standard Processing: Results in 5 working days after sample arrival at the laboratory. Clients organize and cover the costs of sending the samples. Why Test? This genetic test helps breeders identify horses carrying the PSSM allele. Informed breeding choices can prevent the birth of affected foals. While PSSM cannot be cured, muscle function can be managed with dietary changes and exercise routines. The PSSM1 test is required by many studbooks and is highly recommended when considering the purchase of a horse. Testing for PSSM1 as part of the pre-purchase examination can ensure that you are making an informed decision, as the condition can impact the horse's performance and overall health. Learn More Results Description The DNA test results will be one of the following: n/n: Negative for PSSM1. No affected allele present. n/P1: Positive heterozygous for PSSM1. One mutated allele present. The horse can pass the PSSM1 allele to 50% of its progeny. P1/P1: Positive homozygous for PSSM1. Two mutated alleles present. The horse will pass the PSSM1 allele to 100% of its offspring. Additional Information Polysaccharide Storage Myopathy (PSSM1) is a hereditary muscle disease that affects many breeds. The condition is caused by a mutation in the GYS1 gene, leading to an abnormal accumulation of glycogen in the muscles. This can cause symptoms such as muscle tremors, stiffness, reluctance to move, and excessive sweating. Management of PSSM1 includes dietary changes and regular exercise to help mitigate symptoms. Check our FAQs for more information FAQs What breeds are affected by PSSM1? PSSM1 affects many breeds, including Quarter Horses, Belgian Draft Horses, and Warmbloods. The prevalence of the mutation varies by breed, with some breeds having a higher incidence of the condition. How is PSSM1 inherited? PSSM1 is inherited in an autosomal dominant manner, meaning that horses with one (n/P1) or two (P1/P1) copies of the mutated gene can develop the disease. Horses with two copies generally show more severe symptoms. How can PSSM1 be managed? Management includes dietary modifications to reduce starch and sugar intake, and a consistent exercise regimen. These measures can help prevent the onset of symptoms or reduce their severity. Visit our full FAQ page for more details.

DNA test The DNA test verifies the presence of the chromosomal inversion.  The Tobiano coat pattern usually involves some white on all four legs and rounded white spots on the body with sharp, clean edges. Sample 30 to 40 - hair roots - envelope or 5 mL - blood - K3 EDTA tube Turnaround time 2 to 5  working days Why test? This genetic test can confirm is the horse is heterozygous (To/N) or homozygous (To/) for the Tobiano gene. For breeding purposes, homozygous Tobiano horses are highly desirable as they are guaranteed to produce Tobiano foals regardless of their mate. Since Tobiano is only responsible for the white markings of a so called “colored” horse, the test does not determine the horse’s base-color. This is determined using the extension test. The two tests in conjunction not only verify the likelihood of Tobiano being passed to foals, but also the likelihood the foals will be piebald or skewbald. Results description The DNA test verifies the presence of the chromosomal inversion and presents results as one of the following: N/ – Non-tobiano horse. To/N – Positive for the dominant Tobiano gene mutation, carrier of a single inherited copy of Tobiano. Horse’s base color may be modified to varying degrees by the Tobiano markings. To/ – Positive for dominant Tobiano gene mutation, carrying two inherited copies of Tobiano. Will always pass Tobiano to foals. For breeding purposes, homozygous Tobiano horses are highly desirable as they are guaranteed to produce Tobiano foals regardless of their mate. Additional information The Tobiano coat pattern usually involves some white on all four legs and rounded white spots on the body with sharp, clean edges. The head of the horse is usually colored and will not have white caused by the Tobiano gene. The white on the body will generally cross the top-line of the horse. Although white often incorrectly referred to as adding color it is actually a deletion of color. Tobiano is the result of a chromosomal inversion, affecting regulatory regions of the KIT gene. The Tobiano coat pattern is governed by the dominant KIT gene. Only one copy of Tobiano gene (To/N) is required to express Tobiano coat pattern. Homozygosity of the Tobiano gene (To/) may show visual clues (“ink spots” or “paw prints”) but only genetic testing will tell you more conclusively that the horse is homozygous for the Tobiano gene. When there is no presence of the Tobiano gene (N), the Tobiano coat pattern is not possible.

8 panel genetic test for coat colour with results in 5 to 10 working days.   Includes 8 coat colour genetic markers:  2 base colour - Agouti, Extension; 5 dilutions - Cream, Pearl, Champagne, Silver and Dun (D, nd1, nd2) and the Grey* (G/G, G/N or N/N) depigmentation gene. Our Grey test in panels provide the number of copies of the Grey gene (G/G, G/N, N/N) A Genetic Colour Certificate - Coat Genotype and Offspring Prediction of coat colour is provided Sample type: 30 to 40 hair roots  or 5 mL of blood  (K3 EDTA tube) Turnaround time 5 to 10 working days   Additional information DNA tests for coats can be an important tool for selection, elimination of coat-related diseases and enhancing your stud farm. There are various coat colours and tones in the horse species. Judging coat colour by eye is always subjective and can be influenced by a number of environmental factors (light exposure, time of year and feeding) and it doesn’t allow us to predict with any confidence that the “colour” will be passed down. Genetic determination of coat colour can be done correctly in a laboratory using DNA tests. This method allows us to determine with rigour and objectivity the horse´s coat colour and also forecast the potential transmission of “colour” to offspring. Currently more than 16 gene variants have been identified that can influence this phenotypic characteristic.

DNA test The DNA test verifies the presence of the grey mutation. Grey is the dominant gene responsible for the gradual and progressive de-pigmentation (fading) of the carrying horse. Sample 5 mL - blood - K3 EDTA tube Turnaround time 2 to 5  working days Why test? This genetic test can help breeders that are interested in specifically breeding grey foals. Homozygous grey specimens are ideal as they will always transmit the grey gene when bred, thus guaranteeing eventual grey progeny. For the breeder that wants to  “breed-out” the grey modifier to gain non-fading foals may hope for heterozygous grey horses. Some breed-types have a large percentage of grey stock which through historical lineage may harbour colours and dilutions that are ‘hidden’ by the masking effect of the grey. Insight into a foal’s potential to fade: since grey may cause slow de-pigmentation, it may not be visually apparent whether or not a newborn foal will eventually fade to grey. The de-pigmentation process may take many years and therefore DNA testing is useful in the cases whereby a foal is born of one or more grey parents and verification of the presence of grey is necessary. Results description The DNA test verifies the presence of the grey mutation and presents results as one of the following: N/ – Non-grey horse. Negative for grey. Horse will not turn grey. G/N - Grey horse. Positive for dominant grey gene, carrying a single inherited copy. Carrier’s coat modified and will eventually become de-pigmented. Heterozygous grey horses are statistically likely to pass the gene to 50% off their progeny when bred. G/ - Grey horse. Positive for dominant grey gene, carrying two inherited copies. Carrier’s coat modified and will eventually become de-pigmented. Homozygous grey horses are genetically bound to pass the gene to 100% of their progeny when bred, so all foals will receive grey and fade-out. Additional information Grey is the dominant gene responsible for the gradual and progressive de-pigmentation (fading) of the carrying horse. Grey cannot be considered a base-color, or a dilution, but rather a gene which slowly removes pigment from the coat.  This gene is considered to be the ‘strongest’ of all coat modifiers, and acts upon any base-color regardless of the carrying horse’s phenotype. The fading process itself may last for years, but once hair is de-pigmented, the horse’s original colouring will never return. Since grey is a dominant gene, where it is present it is expressed. However, the final phenotype of the carrier will vary from horse to horse. Some grey horses fade to full de-pigmentation (almost pure white) whereas others may be ‘fleabitten’. Fleabitten refers to grey horses with tiny non-faded spots or ‘fleabites.’ The grey carrying horse may also experience de-pigmentation of the skin itself, and before skin is fully faded may display ‘mottling’. Equine melanomas occur most often in grey horses, and it is expected that at least 80% of grey horses will develop melanoma.

About the Test The qPCR test detects the genome (ADN) of Streptococcus equi variant equi, the pathogen (bacteria) responsible for Strangles. Sample Nasopharyngeal swab - dry swab (see AAEP guidelines) Nasal swabs or draining lymph nodes Guttural pouch washes Turnaround time 2 to 5 working days What is Strangles? Strangles is a highly contagious upper respiratory infection of horses caused by the bacteria Streptococcus equi subspecies equi (S. equi). It is transmitted by inhalation or direct contact with contaminated surfaces (for example, horses sharing water buckets). The bacteria colonize the horse’s tonsils and pharynx within hours of infection, and then infect the lymph nodes under and behind the jaw, resulting in abscessation of these structures days later. Horses develop a fever initially, but are typically not contagious during the initial 48-72 hours. Rarely, infection spreads to other parts of the body resulting in abscesses in other organs such as the intestines, kidneys, lungs, spleen, or liver. This is often called “bastard strangles” or metastatic abscessation. A few horses may develop a hypersensitivity reaction to the bacteria with repeated exposure either in the form of infection or vaccination, otherwise known as purpura hemorrhagica. Horses that develop classic clinical signs and are not treated with antibiotics have the potential to develop immune protection for up to five years. Clinical signs Classic clinical signs include a fever (often >103°F or 39.5°C) first, followed by one or more of the following symptoms: depression, thick nasal discharge, and lymph node enlargement under the jaw and/or in the throat latch region. The abscessed lymph nodes may drain externally or into the guttural pouches (blind-end sacs connected to the throat in horses) resulting in nasal discharge. Horses that have been vaccinated for strangles or horses that have previous partial immunity may develop milder signs of upper respiratory tract infection. Bastard strangles cases may develop colic signs, fever, and/or weight loss with or without a history of previous strangles disease or exposure. Horses with purpura hemorrhagica may develop edema of the head, trunk, and/or legs, and broken blood vessels or bruising of the mucous membranes of the mouth, eyes, and nose. Additional signs can include fever, severe depression, and muscle tightness. The severity of symptoms in purpura hemorrhagica cases ranges from mild to life-threatening. Transmission Strangles is caused by oral exposure of a horse to S. equi bacteria. Once within the oral cavity, the bacteria invade the tonsils and subsequently colonize the lymph nodes. Bacteria can be transmitted through contact with pus or nasal discharges from an infected horse, or from contaminated bedding or barn equipment (water troughs, buckets, etc.). Flies may also act as vectors, spreading the bacteria from horse to horse. Under the right conditions, S. equi can survive in the environment for weeks or months. Exposure of a horse to S. equi does not necessarily mean that it will come down with strangles. Factors that influence the risk of disease include dose of bacteria (poor sanitation and direct contact with nasal secretions and pus increase the chance of disease); immune status of horse. Previously exposed horses are often immune to the disease, or do not get as sick as unexposed horses. During the first three to six months of life, foals are often protected by maternal antibodies. Vaccination can also increase resistance to the disease; stress (poor nutrition, overcrowding, lengthy transportation, or pre-existing diseases increase the risk of strangles). Strangles may be transmitted by “silent shedders” who do not display signs of disease. These horses commonly carry the strangles organism in the guttural pouch, an air sac at the back of the horse’s throat. Detection of these animals requires guttural pouch endoscopy (passing an endoscope via the horse’s nose into the guttural pouch). Strangles is most commonly transmitted by acutely ill or recovering horses that are still shedding bacteria in their nasal secretions. Bacterial culture results have a turnaround time of 2 to 3 days. The DNA test known as Polymerase Chain Reaction (PCR) takes less than a day. However, it may take an additional 1 to 2 days to send samples to the laboratory. Prevention Biosecurity on the farm is necessary to prevent the spread of disease. Isolate new horses for three weeks prior to introducing them to the rest of the population. Isolate any horse with a fever and signs of strangles. Do not share tack or equipment between sick horses and others. Perform twice daily monitoring of rectal temperatures of all horses in an outbreak to identify new cases. Stop all movement of horses to and from the farm when strangles is identified. Disinfect water buckets daily. Use strict hygiene between horses to reduce the spread of the disease. Ideally, three throat flush samples are obtained from recovering horses and any horses who were in contact with sick horses at approximately weekly intervals and tested for S. equi subsp equi by PCR and culture. Identification of strangles bacteria in clinically recovered horses may mean the guttural pouches have retained some infection. Endoscopy of the guttural pouches provides visualization of any pus or dried debris (chondroids) that harbor the bacteria. A small number of horses will recover from strangles and continue to shed bacteria from the guttural pouch, causing recurrent farm outbreaks. Detection and treatment of these “silent carriers” (S. equi bacteria in guttural pouches) via endoscopy and PCR is essential for preventing disease recurrence on a farm. Discuss vaccination types and recommendations with your veterinarian. Vaccination does not provide 100% immunity against S. equi infection. Vaccination is not recommended during or within two years of a strangles outbreak due to the increased risk of purpura hemorrhagica.

Pathogen test  This is one of the internationally imposed tests in the import/export of live equines or semen/ova and embryos intended for assisted reproduction. PTE029/7 AGID test (Coggins test) to detect antibodies against equine infectious anemia  Equine Infectious Anaemia is a disease listed in the OIE Terrestrial Animal Health Code and countries are obligated to report the occurrence of the disease according to the OIE Code. Sample 5 mL - blood - serum tube Turnaround time 2 to 5 working days   What is Equine Infectious Anemia? Equine infectious anemia is a very old viral disease that affects horses, asses, mules and hinnies worldwide. It is subject to tight controls in the import/export of live equines and their products Clinical signs This infection may have an acute, chronic or sub-clinical (silent) phase. The acute phase characterised by intermittent fever associated with depression, lethargy, increased heart and breathing rates, haemorrhaging, diarrhoea with blood, bleeding wounds that won’t heal, lack of coordination and rapid weight loss. It can also cause petechial haemorrhages of the mucous membranes and general oedema more evident in the legs and jaundice. The chronic phase characterised by recurrent episodes of fever, anaemia and thrombocytopenia (decrease of blood platelets) interspersed with periods of normality. These episodes will be spread out over time. This disease is often fatal during the acute or chronic phase. Should the animal survive the acute and chronic phase, it enters a silent phase with no evident signs of illness for the remainder of its life. In this silent phase the virus persists but the clinical signs are only manifest if the immune system is weakened by another disease, stress or the administration of corticosteroids. Transmission EIA is caused by a lentivirus of the HIV family, the equine infectious anaemia virus. The virus can be passed from one horse to another through fly, or more rarely, mosquito bites, or by direct contact with blood or blood derivative products (serum and/or plasma). Such as, for example, by: sharing objects contaminated with infected blood (needles, branding tools, etc). The virus can also be passed down from mare to foal via the placenta or, more rarely, in the mother’s colostrum or milk. Potentially, the virus can be transmitted by semen. Prevention There is no treatment, cure or vaccine for this infection. Prevention is crucial to avoid it being passed on. Serological tests for EIA must be done for any horse with anaemia and thrombocytopenia of unknown origin. Regular tests must be done on a yearly basis to keep the holding free from EIA. It is advisable to test studs and brood mares every 90 days in the breeding period.

This genetic test helps breeders identify horses carrying the PSSM1 and WFFS alleles. Informed breeding choices can prevent the birth of affected foals. While PSSM1 affects muscle metabolism, WFFS is a fatal connective tissue disorder. Testing for these conditions is often required by studbooks and is highly recommended during pre-purchase exams to ensure the horse's health and performance. Learn More Results Description The DNA test results will be one of the following: PSSM1 n/n: Negative for PSSM1. No affected allele present. PSSM1 n/P1: Positive heterozygous for PSSM1. One mutated allele present. The horse can pass the PSSM1 allele to 50% of its progeny. PSSM1 P1/P1: Positive homozygous for PSSM1. Two mutated alleles present. The horse will pass the PSSM1 allele to 100% of its offspring. WFFS n/n: Negative for WFFS. No affected allele present. WFFS n/WFFS: Carrier for WFFS. One copy of the mutated allele present. The horse can pass the WFFS allele to 50% of its progeny. WFFS WFFS/WFFS: Positive for WFFS. Two copies of the mutated allele present. The foal will exhibit severe clinical signs and must be euthanized shortly after birth due to the untreatable nature of the disease. Such foals will not survive to adulthood and hence will not pass on the allele. Additional Information Polysaccharide Storage Myopathy (PSSM1) is a hereditary muscle disease affecting many breeds, caused by a mutation in the GYS1 gene. Warmblood Fragile Foal Syndrome (WFFS) is a fatal genetic defect of connective tissue, resulting from a mutation in the PLOD1 gene. WFFS is characterized by hyperextensible, fragile skin and mucous membranes, leading to severe lesions and often resulting in euthanasia of affected foals shortly after birth. Both conditions can significantly impact a horse's health and performance, making genetic testing an essential tool for breeders and buyers. References Ablondi, M., et al. (2022).

Check our FAQs for more information FAQs What breeds are affected by PSSM1 and WFFS? PSSM1 affects many breeds, including Quarter Horses, Belgian Draft Horses, and Warmbloods. WFFS primarily affects Warmbloods but has also been detected in breeds like Thoroughbreds, Knabstruppers, Haflingers, and American Sport Ponies. How are PSSM1 and WFFS inherited? PSSM1 is inherited in an autosomal dominant manner, meaning horses with one (n/P1) or two (P1/P1) copies of the mutated gene can develop the disease. WFFS is inherited as an autosomal recessive trait, requiring two copies of the mutated gene (WFFS/WFFS) for the disease to manifest. Affected foals with two copies of the WFFS mutation will not survive to adulthood and must be euthanized shortly after birth. How can PSSM1 and WFFS be managed? PSSM1 management includes dietary modifications to reduce starch and sugar intake, and a consistent exercise regimen. WFFS, however, is a lethal condition with no cure, emphasizing the importance of genetic testing to inform breeding decisions and avoid producing affected foals.

Buy a Base colour test and find out if your horse's base colour is Black, Bay or Chestnut. Results within 24 h are available. DNA test for the Agouti and Extension loci that controls distribution of Black and Red pigment throughout the coat. Sample 30 to 40  hair roots  or 5 mL - blood - K3 EDTA tube Turnaround time Standard processing - Results in 3-5 working days after sample arrival at the laboratory. Clients organize and support the costs of sending the samples to the laboratory. PREMIUM processing - Results in 1 day after sample arrival. Includes free express delivery** . The laboratory organizes Express shipping with pick-up of the package at the client's address and delivery at the laboratory. ** PREMIUM SERVICES INCLUDE AN EXPRESS SHIPPING DELIVERY FOR EUROPEAN COUNTRIES FROM NON-REMOTE REGIONS. Check here to know if you are in a remote European region. For remote/outreach regions EXTRA fees are applied.    Why test? Horses have only three base colours: Bay, Black or Chestnut These different colours are controlled by 2 loci, the Extension  (Red/Black) and Agouti. The Extension locus controls the production of black or red pigment throughout the coat. The allele for black color (E) is dominant over the red allele (e), so a horse only needs one copy of the black allele to appear black-based. But if the horse has two alleles (e/e) he will appear Chestnut. The Agouti locus can then modify black pigment by pushing it the horse's points, creating a Bay. The Agouti A allele is dominant, so a black pigmented horse only needs one copy (heterozygous) of the A allele to appear Bay. The Agouti (a) allelle is recessive, thus, a horse needs two copies (homozygous) of the recessive allele (a) at the Agouti locus to appear Black. Agouti has no effect on red pigment, but the red allele (e) is dominant over the (a) allele. This means a Chestnut horse (e/e) can carry one or two copies of the Agouti recessive (a) allele and will look no different from chestnut horses with  Agouti dominant alleles (e/e a/a, e/e A/a,  e/e A/A).   Results description Base Colour Extension Agouti Bay E/E or E/e A/A or A/a Black E/E or E/e a/a Red e/e A/A, A/a or a/a   References Rieder, S., Taourit, S., Mariat, D., Langlois, B., & Guérin, G.

  MIM (PSSM2) DNA Test Ensure the Health and Performance of Your Horses with Accurate MIM Testing. Our DNA test identifies the presence of genetic variants associated with Muscle Integrity Myopathy (MIM), formerly known as PSSM2, which affects muscle function and structure. Sample Requirements 30 to 40 hair roots - envelope Alternatively, 5 mL blood - K3 EDTA tube Turnaround Time up to 15 working days Results Description The DNA test identifies six genetic variants that predispose horses to developing symptoms of Muscle Integrity Myopathy: P2: Myotilinopathy P3: Filaminopathy P4: Myozenin-3-Myopathy P8: PYROXD1-Myopathy Px: CACNA2D3-Myopathy K1: COL6A3-Myopathy Genetic Inheritance Muscle Integrity Myopathy (MIM) is caused by a hereditary predisposition involving multiple genetic variants. These variants disrupt the structure and function of muscle fibers, leading to symptoms such as muscle stiffness, unexplained lameness, and difficulty building muscle. Clinical Signs and Affected Breeds Symptoms of MIM can vary widely among horses and include unexplained lameness, muscle stiffness, difficulty with gait changes, reluctance to move, muscle atrophy, and behavioral changes. Almost any breed can be affected, with common occurrences in breeds like Quarter Horses, Warmbloods, and Thoroughbreds. Why Test? Testing for MIM is crucial for breeders and owners to make informed decisions. By identifying carriers of the genetic variants, breeding choices can be optimized to prevent the spread of these disorders. Additionally, knowing a horse's genetic status can help manage and mitigate symptoms through tailored exercise and feeding protocols. Learn More Detailed Results Description The DNA test results will indicate the presence of the following genetic variants: P2: Myotilinopathy P3: Filaminopathy P4: Myozenin-3-Myopathy P8: PYROXD1-Myopathy Px: CACNA2D3-Myopathy K1: COL6A3-Myopathy Additional Information Muscle Integrity Myopathy (MIM) is a genetic disorder that disrupts muscle function and structure, leading to various clinical signs. While it is not possible to cure genetic disorders, optimized management through diet and exercise can help mitigate symptoms, allowing horses to lead normal lives. References Generatio. Muscle Integrity Myopathy in HorsesEquiSeq. Polysaccharide Storage Myopathy type 2 (PSSM2) Check our FAQs for more information FAQs What breeds are affected by MIM? Almost any breed can be affected by MIM, with common occurrences in breeds like Quarter Horses, Warmbloods, and Thoroughbreds. How is MIM inherited? MIM is caused by multiple genetic variants that disrupt muscle structure and function. These variants are inherited and can predispose horses to developing symptoms of exertional myopathy. How can MIM be managed? While genetic disorders cannot be cured, their symptoms can often be managed through optimized feeding and exercise protocols. Identifying genetic variants through testing allows for tailored management strategies to mitigate symptoms. Visit our full FAQ page for more details.
