Plain-English summary
A 16-hour-old white foal, born to a registered quarter horse mare, was seen by a veterinarian because it was showing signs of colic, which is a type of belly pain. The foal was diagnosed with Overo lethal white syndrome, a genetic condition that affects the intestines and prevents normal digestion. DNA testing confirmed this diagnosis, but unfortunately, there is no treatment available for this condition. Because of this, the decision was made to euthanize the foal to prevent suffering.
Abstract

This was confirmed by DNA testing. Since there is no treatment for Overo lethal white syndrome, the foal was euthanized.
