i believe he is the 99'-- i don't have his papers yet as i am still paying for him

i know he has qh in him-- im not trying to be naive here, and if you could tell me if he was tested that would be fantastic

i didn't understand what the test was-- now that i know what it is i can research more about it as i am very curious about it

[Acme Acres]

I don't see any impressive on him at all. But he does have a nice pedigree!

Didn't copy right but gives you names. So, unless he would trace to Impressive, no need to test. Never hurts to check names though, people can be sneaky and get off the "impressive" name to get people to think they're not even Impressive bred but are, or horses do have it in their names but not Impressive bred. You can find a lot of good info on HYPP around the internet.

[Brogan]

i didn't think he had any

yeah i got pretty lucky with him-- he really is one of a kind

and i was just looking through the APHA site and hypp testing is not a requirement-- which i think is kind of weird considering a lot of paints have impressive lines in them

HYPP stands for "Hyperkalemic Periodic Paralysis". It has been traced to the Quarter Horse stallion Impressive (though there are rumors of cases of HYPP that were not connected to Impressive, but no confirmed ones yet I believe).

HYPP basically causes afflicted horses to have extremely high potassium levels. And episodes can range from mild muscle twitching that is undetectable to the human eye to noticeable twitching and their skin moving. It also causes the hind end to become temporarily paralyzed and excessive yawning. A severe episode can cause the muscles in and around the heart and lungs to jerk and paralyze as well, causing death by heart attack and/or suffocation.

There is no way to determine how bad an episode will be. A horse's very first attack could be the one that causes a fatal heart attack. It is very popular with some Halter breeders because the minor episodes that cause the muscle twitching have the side-effect of the horse "bulking up" and developing the large muscles favored in the Halter ring.

HYPP horses live decent lives with careful management, but even this is not a guarantee they will not have an episode.

A horse can be N/N, N/H, or H/H.

A horse that is N/N does not have or carry HYPP.

A horse that is N/H carries one copy of the HYPP gene. The horse has a 50% chance to pass this gene on to its offspring. Please know that an N/H can still have episodes. It is not like having a single copy of SCIDS or LWO; a horse can carry one copy of those and is perfectly healthy. HYPP has a good chance of affecting a N/H horse though sometimes they do not.

A horse with H/H has two copies of the HYPP gene. This horse will give HYPP to their foals 100% of the time. They will have HYPP episodes; all H/H horses have them.

ApHC doesn't require testing either. ApHCC does though

Is this true? I thought it was just H/H they had a problem with(registration wise) Maybe thats why my girl isnt registered, and where do you find this information on the AQHA website, I am a member and do have her pedigree pulled, but it doesnt show N/N, N/H, or H/H anywhere, but on all breed it shows her grandfather listed as N/H. Her mother isnt listed and dad is a TB.

AQHA will not register specific N/H in a few years, hoping to rid of the disease. I think it will just lead to more unregistered show horses.

Found it:

October 17, 2003; letter from AQHA President Steve Stevens:
HYPP
The next important topic relates to Hyperkalemic Periodic Paralysis (HYPP). The stud book and registration committee has asked the executive committee to obtain input from the membership regarding this important matter that will appear on their agenda at the Reno convention in March 2004. The proposal is as follows:
1. Rule 227 will be amended making foals of calendar year 2006 and after ineligible for registration if they are descendants of the stallion Impressive, AQHA Number 0767246, and found to be HYPP positive (H/H).
2. Additionally, Rule 227 will be amended to provide that foals of 2010 and later that are found to be HYPP (N/H) will only be eligible for registration as geldings or non-breeding mares.
Again, make your elected representatives and AQHA staff aware of your feeling regarding this issue.
