For years, veterinarians and breeders were left searching for answers as healthy Quarter Horse foals suddenly developed severe neurological symptoms, lost coordination, and rapidly deteriorated. Now, researchers at the University of California, Davis (UC Davis) have identified the genetic cause of Equine Juvenile Spinocerebellar Ataxia (EJSCA), a fatal neurologic disease affecting Quarter Horse foals.
In this video, we explore the groundbreaking discovery of the FDXR gene mutation, how this devastating disease affects young foals, and why this breakthrough could help breeders prevent future cases through genetic testing.
This discovery represents a major advancement in equine medicine, horse breeding, and veterinary genetics, providing long-awaited answers to one of the most heartbreaking diseases affecting Quarter Horses.

Frequently Asked Questions
What is Equine Juvenile Spinocerebellar Ataxia (EJSCA)?
EJSCA is a fatal inherited neurologic disease that causes progressive loss of coordination and nervous system degeneration in young Quarter Horse foals.
UC Davis researchers identified a mutation in the FDXR gene as the cause of the disease.
Genetic testing can identify carrier horses and help breeders avoid producing affected foals.
Who should test their horses?
Quarter Horse breeders and owners with breeding animals may benefit from testing to determine carrier status.
