GBED

Glycogen branching enzyme deficiency is an inherited disorder found in Quarter Horses and related breeds. The disease results in weakness affecting heart and skeletal muscles, and has been reported to be responsible for about 3% of late term abortions and stillbirths. The mutation, which causes this disease, has been identified by Dr. Stephanie Valberg and Dr. James Mickelson of the University of Minnesota, and licensed for diagnostic use by Vetgen. It is estimated that about 10% of Quarter and Paint horses carry the mutation.  VetGen tests using either oral cheek swabs plus hair or blood as DNA sample.
