Sobre o teste

Garanta que a linhagem do seu cavalo está livre de doenças genéticas com o nosso painel abrangente de testes de DNA. Certifique o seu cavalo contra 10 doenças genéticas: SCID, LFS, CA, PSSM1, HYPP, GBED, HERDA, MH, CM, WFFS.

Porquê testar?

O nosso teste Certificado de Linhagens Livres de Doenças Genéticas ajuda criadores, compradores e certificadores de livros genealógicos a garantir que os cavalos estão livres de doenças genéticas. Isto assegura cavalos mais saudáveis, decisões de reprodução informadas e maior tranquilidade.

Sinais clínicos

What each disease looks like in an affected horse:

SCID (Severe Combined Immunodeficiency): the foal looks normal at birth, then from about 10 days old has repeated infections and dies in the first months
LFS (Lavender Foal Syndrome): a pale-coated newborn foal with fits, unable to stand or nurse
CA (Cerebellar Abiotrophy): head tremor and poor balance, usually starting between about six weeks and four months of age
PSSM1 (Type 1 Polysaccharide Storage Myopathy): stiffness, reluctance to go forward and tying-up after exercise
HYPP (Hyperkalemic Periodic Paralysis): attacks of muscle tremor and weakness that come and go
GBED (Glycogen Branching Enzyme Deficiency): abortion, stillbirth, or a weak foal that dies within weeks
HERDA (Hereditary Equine Regional Dermal Asthenia): fragile skin that tears and scars, often first noticed when the horse is started under saddle
MH (Malignant Hyperthermia): a normal-looking horse that has a fast, potentially fatal attack during anaesthesia, hard exercise or stress
CM (Congenital Myotonia): muscles that are slow to relax, so the pony is stiff and struggles to get up
WFFS (Warmblood Fragile Foal Syndrome): abortion, stillbirth, or a foal born too weak and fragile to survive

None of these signs is unique to one disease. In a sick horse, your veterinarian makes the diagnosis from the examination and the DNA result.

Transmissão

Seven diseases are recessive: SCID, LFS, CA, GBED, HERDA, CM and WFFS. A foal is affected only if it gets one copy from each parent. A horse with one copy is a healthy carrier.

Carrier x clear gives 50% carriers, no affected foals
Carrier x carrier gives 25% clear, 50% carriers, 25% affected

Three are dominant: PSSM1, HYPP and MH. One copy is enough to make a horse susceptible.

One copy x clear gives 50% clear, 50% susceptible
One copy x one copy gives 25% clear, 50% one copy, 25% two copies

Each disease is inherited separately. None of the genes is on a sex chromosome, so colts and fillies are affected equally.

Prevenção

Preventing affected foals.

Never mate two carriers of the same recessive disease
A carrier mated only to partners that tested clear produces no affected foals, so good bloodlines can stay in use while the variant is bred out
Breeding a horse positive for PSSM1, HYPP or MH passes the risk on to its foals
Test the partner too: the panel shows which of the ten diseases matter for each mating

Looking after a positive horse. A horse positive for PSSM1, HYPP or MH needs a plan made with your veterinarian: feeding and exercise for PSSM1 and HYPP, and precautions before any anaesthesia for MH. Tell your veterinarian the result before any operation.

FAQs

At what age can a horse be tested?
Any age. The genotypes are fixed at conception, so one test lasts for life.

What is not included?
Lethal White Foal Syndrome (frame overo), coat colour genes and the MIM (PSSM2) panel. MIM is sold separately, and the link between its variants and disease has not been confirmed by independent research.
