Unfortunately, under the genetic law of averages, many of them also would be HC gene carriers. Steer clear of the King bloodline if you can, but if you already have a horse with this lineage consult with your vet about having him or her tested, especially if you plan on breeding.
Join us as we interview leading equine researchers from the University of KentuckyPoco Bueno has been identified as the sire line associated with the brutal affliction known as hyperelastosis cutis or hereditary equine regional dermal asthenia (HERDA). Although these stallion lines were extremely popular at one time, today these bloodlines are just as well known for their genetic flaws and even difficult temperaments.
"It doesn't matter what you call it," says Rashmir, "it's the same disease." However, when two carriers are mated, there is a 25% chance the offspring will have HC. If you enjoyed the article please take a moment to pin it to Pinterest or share on social media. The genes that cause HC are recessive, and it takes two to tango.
In dramatic cases, says Rashmir, the skin can split along the back and even roll down the sides, with the horse literally being skinned alive.
It is primarily down through Poco Bueno's bloodline, say researchers at Mississippi State University and Cornell University, that the recessive gene that causes hyperelastosis cutis (HC) has passed.
Many are not. He was a giant among horses.
He says the announcement by Rashmir and Winand, to his knowledge, is the first public revelation concerning the Poco Bueno bloodline being the primary reservoir for the HC gene. Without this, the horse cannot store sugar properly and they will die within days or, at maximum, 2 months.There is a 100% mortality rate for any foal diagnosed with GBED.
This disease does not usually present until the horse begins training, usually around the age of 2 or 3, when a saddle or rider causes pressure on the horse’s skin, forcing the separation and subsequent injury. "All of the horses diagnosed with HC are related," Rashmir says. The truth is, you should always study a horse’s bloodlines, especially if it is a Quarter Horse.
Rashmir and Winand are collaborators on research involving hyperelastosis cutis.

Behavioral issues like bucking or hard-headedness may only be situational and in the right hands, a “bad” horse could turn out to be an extraordinary one.

Some of the bloodlines have serious, known genetic issues and should be tested or be able to show proof they are clear of the issues prevalent in their line. Poco Tivio became well known for his excellent producing daughters, many of which were bred to Doc Bar. With HC, both parents must carry the recessive gene for the horse to be afflicted.
While this suggests that Poco Bueno may have inherited the HC mutation from his sire, this may not be the case. The goal is to determine which ones are and avoid breeding carrier to carrier.Les Sellnow is a free-lance writer based near Riverton, Wyo. If it's not available.
ACVS, associate professor of surgery and head of the Hyperelastosis Cutis Research Program at Mississippi State University, and Nena Winand, DVM, PhD, a geneticist and assistant professor in the Department of Molecular Medicine at Cornell University, opt for hyperelastosis cutis. King and Poco Bueno became legends in their time, and in the breeding shed they sired outstanding cutting and performance horses. Just where along the line did the mutation occur?
Winand says that another study, also based on statistics published in the 2004 Winand emphasized that other disciplines besides cutting are involved in these bloodlines–reining, working cow horse, and even pleasure horses. Unfortunately, a fatal gene mutation can occur with some horses that carry the King-P234 lineage. This means that both sire and dam must possess the recessive gene in order for an offspring to possibly be afflicted with HC. He sired an excellent racehorse in Little Joe. It is not supposition at this point, Winand and Rashmir state. Also watch out for or one of his most popular sons Doc O’Lena, another well-known carrier of the disease.
The mutation causes the cells within a horse to not recognize the GBR gene, which in turn makes its body unable to produce the GB enzyme. The Quarter Horses with Impressive bloodlines used in breeding today are required to be tested for HYPP in order to be registered, and AQHA will no longer register a foal that tests H/H for the gene. Their descendants still make premier head and heel horses. Breeding decisions for the horse carrying the gene are critical in order to lessen the chance of producing a foal that is positive for the gene. "It is not just a problem with cutting horses," she says. Think of it like glue holding the skin layers together, only with HC, the glue is inferior.

That way you can make the best decision and avoid a lot of expensive and heartbreaking problems. Under the genetic law of averages, here's how it works, according to the two researchers.
This thing (HC) is going to mushroom in the next several years, and there is no way to stop it. It has been established, say Rashmir and Winand, that the recessive gene was passed on to Doc O'Lena through his dam, Poco Lena, rather than through his sire, Doc Bar. For example, Quarter Horse names include Doc, Poco, Bar, Zip, Peppy, and Leo.
That, says Winand, is unfortunate. Click There are cases where horses with HC have lived to a fairly old age, says Rashmir, but they are treated as pets and great care must be taken to prevent trauma that can rip the skin.
Although affected horses can be made more comfortable and their lives prolonged, there is no cure.
