Nena Winand, DVM, PhD at the Cornell University College of Veterinary Medicine, explains her current interest in identifying the causative mutation in Ehlers-Danlos syndrome in American Quarter horses. Ultimately she hopes to create an assay to screen for the mutation in order to help breeders identify carriers of the disease.
