I just read something about HERDA? What is it?

[Dawn]

It's a skin disorder where the skin isn't 'attached' to the body to put it simply. It also occurs in humans but under a different name.

It's associated with...I'm wanting to say the Poco Bueno line.

[Little Red Dun]

Hereditary Equine Regional Dermal Asthenia.

It was traced to Poco Bueno. Basically the affected horses' skin develops lesions, scars badly, and "tears away."

Here's some information on HERDA: HERDA

Thanks, I'll check that site right now!

[Ms.Cinderella]

its pretty bad! Horses from zippo, barr,(like little red dun said)Poco bueno umm and quite a few more carry the gene for it. The skin actually tears or peels off from pressure i believe. I have like a 3 page article on it. If I can find It Ill post more info. Its found in QH's and paints.. I think... hold on lemme go find this article

UC DAVIS RELEASES HERDA TEST.


Last month, The American Quarter Horse Journal reported Cornell University had released a test for the hereditary disease HERDA that is found predominantly in American Quarter Horses.
The University of California-Davis, has now also released a test for the disease. The American Quarter Horse Foundation and the Center for Equine Health at the UC Davis School of Veterinary Medicine funded the research that identified the gene responsible for the mutation.
HERDA most commonly affects certain lines of cutting horses. UC Davis’ study of a control group suggested that 3.5 percent of Quarter Horses are carriers of the disease. Because carriers do not show symptoms of the disease, which include loose skin, lesions and inability for wounds to heal, owners and breeders rarely know they have a carrier.
Most symptomatic horses diagnosed with HERDA are euthanized because they are not able to be ridden and have a low quality of life due to the condition of the skin, scarring and lesions along their backs. Horses don’t typically show symptoms until they are 2 years old.
The DNA test is available through the UC Davis Veterinary Genetics Laboratory. Further information, including pricing for the test, can be found at HERDA.

Just like the test for HYPP there is no reason why someone shouldn't do this specially if buying a young horse. It probably won't be long before it becomes mandatory by AQHA.

Does anyone know how long it takes for signs and symptoms to show?
