I have a grandson of Impressive and he is N/N.

I think that moving to make a stricter rule about registering would go a long way to stopping this disease in it's tracks. Of course we can't control who breeds mutt horses, but if the AQHA would stop registering any carrier (they already refuse to register H/H, they should include N/H with that as well), then the number of foals born with it would decrease dramatically over the next 10-15 years.

My mare (who is APHA) has Impressive in her pedigree, but I did get her tested and she is HYPP N/N :)

Farmpony - ty for the reply.

I didn't know my foal's breeding so I tested him anyway not even being sure if he was full QH. I figured for the $50 rather be safe than sorry since his dam came from auction, looked full QH and it certainly was possible.

I too know someone with an HYPP horse (N/H) who is occasionally symptomatic. He's an app - so I assume impressive has been bred to apps as well meaning it's not *just* QH's. She manages with diet and he does very well.

Question - are there any HYPP horses that are NOT impressive bred?

I don't believe so, since he was the one responsible for the mutated gene that caused it. And yes, Apps and Paints can also have HYPP, depends on their bloodlines. Here's a good resource too and I suggest emailing them if you've had your horse tested so they can keep updated - I did :)

ty. Id add my horse to the list but his lineage is as such:

Dam: liver chestnut mare - "never bred, easy to handle, reining trained, sound" from auction. (wanna guess how much of that description is true!? LOL)
Sire: someone that mysteriously bred the never been bred well trained easy to handle totally sound mare some time before auction - or god as it was obviously an immaculate conception. Duh.

HYPP horse tested: cute (we think) palomino-ish colt (about to be gelded) named Logan's Run. Yeah...

LOL!

Nope. I just went to the AQHA website and copied the fact sheet for everyone.

AQHA's HYPP FACT SHEET
• Hyperkalemic periodic paralysis (HYPP) is an inherited disease that leads to uncontrolled muscle twitching or profound muscle weakness, and in severe cases, may lead to collapse and/or death.
• HYPP is listed as a genetic defect in AQHA's rules, along with Parrot Mouth and Cryptorchid conditions.
• To date, HYPP only has been traced to descendants of IMPRESSIVE, #0767246.
• Having negative (N/N) results on file may prevent a horse's offspring from being tested.
• Foals born in 1998 and later and tracing to IMPRESSIVE will have a statement placed on their Certificates of Registration that recommends testing for the condition unless test results indicating the foal is negative (N/N) are on file with AQHA.
• AQHA will test any foals who are required to be parentage verified and who trace to IMPRESSIVE for HYPP prior to them being registered. This testing will be performed with the same DNA sample submitted to the laboratory for parentage verification.
• AQHA will accept HYPP test results only if performed through a licensed laboratory. These currently include:
Veterinary Genetics Lab at University of California at Davis
Shelterwood Laboratory at Carthage, Texas
IDEXX Laboratories, Markham, Ontario
NSW Agriculture in Australia
Veterinary Diagonostics Center, Fairfield, Ohio, (800) 625-0874
Stormont Labs, Woodland, California, (916) 661-3078
Gene Check, Inc., Ft. Collins, Colorado, (940) 472-9951
Maxxam Laboratory at Guelph, Ontario
Other laboratories are in the process of being licensed.
• Beginning with the 2007 foals, all Impressive progeny are required to be parentage verified and HYPP tested subject to the conditions listed in rule 205. Any that test H/H will not be eligible for registration.
• Possible results of HYPP testing are N/N, N/H and H/H.
HYPP is inherited as a dominant trait, which means a heterozygous (N/H) stallion or mare bred to a normal (N/N) horse will result in approximately half of the offspring being affected and half being normal. The rare homozygote (H/H) usually is severely affected with the disease and will pass the gene to its offspring 100 percent of the time.
•HYPP can be treated through diet and medication in most cases.
• AQHA Testing Kits can be ordered for $40.

While this might be true is some respects. What I see happening is that there will just be more grade horses with it and no one will know until something goes wrong. I would rather let them keep registering the horses as they are now and put the info on the papers as they do now. It has to come down to proper education of breeders and even more so of owners who buy the horses.

Not to mention judges.

Rule changes. Let them register them, but make it a disqualifier or a major fault in the halter classes. That's the only way. (In my opinion)

Thanks, my internet was being wonky when I was trying to find that....

I read somewhere that it was possible it came from his dam as there was a apparently a grade half-brother to Impressive who showed some symptoms.

Seeing as it is pretty much impossible to tell exactly where the original mutations happened now, I'm guessing someone got sick of Impressive name bashing and wanted to make it not this one particular horse's fault. Which I wouldn't blame them if they were a breeder of Impressive line horses. I would get angry if they were breeding H/H or N/H horses though.
