Impressive?

So I was looking at buying a horse that has Impressive bloodlines... And I couldn't remember, was there some kind of genetic disease that Impressive lines carry sometimes? If so, what is it, and there's a way to test for it, right?

its called HYPP and im pretty sure you could send in a sample of the horses hair and they could get you the results. but i may be wrong.

Thanks. Yeah, that's what it is. Since he's a gelding, I really don't care if he'll pass it on to his offspring, but it's sort of imperative that he doesn't go into cardiac arrest, as the little definition thing says...

I'll just ask if he's been tested. Thanks again!

Yes, its Hypp and make sure he is tested before you buy him. Even if he is H/N he could still have a fit, which are horrible to watch and could end up killing him. Make sure he is N/N.

There is nothing wrong with an NH horse (my mare is) as long as you know what to feed, what to look out for as symptoms of an attack and what to do when a horse is going into an attack or is having an attack.

UCDavis can test for the disease. It's $50 and you have to send in a hair sample (from the mane, depending on age) and within a week or so, you'll have the results.

http://bringinglighttohypp.org/ this is a very good website that has a ton of informationi about Hypp.

I now someone that had a NH horse and knew what to watch for and she ended up having a fit and died. I think each horse is different. I would have the horse tested before you purchase. otherwise I havent had any problems with the impressive lines... I think the tests can be done through AQHA also and then they will put hypp N/N on the papers.

I have an Impressive granddaughter that is NN. I love her to pieces, but I would NEVER own an NH or HH horse. Some may be non-symptomatic, but that can change one day.

To the OP, if the horse in his pedigree that goes back to Impressive (sire, dam, grandsire, etc,) has been tested negative, NN, then your horse will also be NN.

it should say on her papers what she is. If both her parents are NN then you have nothing to worry about. How old is this horse?
