Hereditary equine regional dermal asthenia (HERDA)

Summary

HERDA is one of the 5 tests in the 5-panel. It is useful for Quarter Horses, Paints, Appaloosas, Quarter Ponies and any other breeds with some Quarter Horse bloodlines. Horses with two copies of the HERDA gene have extremely fragile skin, particularly along their back. Their skin can rip or tear easily. The large wounds that result from this tearing are painful and like most wounds on horses carry a substantial risk of infection.

Horses with one copy of the HERDA gene (HERDA carriers) are not affected.

The HERDA carriers are most commonly found in cutting horse lines. HERDA also exists outside of the cutting horse population, but is rarer.
