Hereditary equine regional dermal asthenia in Quarter Horses

Horses homozygous for Hereditary equine regional dermal asthenia (HERDA) appear normal at birth. However, within the first two years of like the skin becomes loose and hyper extensible and wounds occur. This results in disfiguring scars.

Because of the popularity of certain linages, HERDA horses will continue to be produced. Managed breeding strategies based upon DNA testing of horses or embryos is currently the only method available to minimise the production of affected horses. More research needs to be performed to look for closely linked performance genes of HERDA carriers.
