Does anyone know of any HYPP testing centres in the uk as I'm buying a quarter horse and want them tested? If anyone has been through the process here I'd like to know more.

If people could let me know asap, it would be very appreciated.

Regards all.
 
Hi,

If the horse is registered with the AQHA (and it can be even if it is in the UK) then it will have been tested if there is Impressive lurking in there somewhere.

I cannot believe that horses registered with AQHA-UK would NOT have the HYPP testing as mandatory for Impressives.

does your horse have impressive anywhere in his pedigree ??? if not its very very unlikely to have HYPP

and most horses that do have it on the papers ... www.aqha.com
just search for HYPP there is lots of info.. hope this helps
 
Hi all - thanks for your responses. I've now found a lab - animal genetics that will test for HYPP and other diseases if needed.

I don't want to reopen the debate on HYPP as I've posted lots of info there on it. Just to recap though - only foals born after 2007 in the UK have to be tested for the UK AQHA and foals in the US after - 1996 (I think). So older horses won't necessarily have it on their papers unless the owner chose to do it. BUT although its all traced back to the horse Impressive - his line has been interbred with lots of non-QH including Arabs and Paints and these breeds now also show the HYPP gene as can any horse who has ever had any Impressive blood in their history and people did get very quiet about whether there was his blood ina horse (and if its not a registered horse, you'd never know anyway - you could have a horse from 2 Arab parents of which 1 or both may have interbred with a QH at some point in their background & you won;t necessarily know.)

Anyway - thx to all. I only mention the above as even in QH circles people don't realise the extent of HYPP in equines and wrongly believe its just in the QH population. The test is only £17 so I'd now test any horse I'd buy for safety reasons alone.
 
Hi, please can I ask where you found the testing for £17? I am looking into getting my mare tested for hyPP. I have only started to research this week. She is sports horse passports but is homyzygous and paint. Having very bad issues for her. 😞😕

Had mine tested by a Manchester lab as he is a mongrel DNA tested to Impressive as his sire. He tested negative, but my vet and I are convinced that he has it. Does anyone know if fake negatives are common, I gave them plenty of good fresh hair roots!?

I've got a great result from using alcar if anyone is fed up with feeding masses of oil. All symptoms totally gone.

Ycbm can I ask what symptoms were ? I may be going down a completely wrong route with my mare but she reacts very similar to tying up but totally fine afterwards as if nothing has happened.
 
Very stiff muscles after exercise in a newly broken horse who was being gently schooled and short hacks. He never tied up,
his muscles just felt more solid than they should all the time.

False colic, stamping his feet and looking around at his 'sides', but actually probably looking at his sore bottom muscles.

Severe incoordination on rough sloping ground, where he had no strength in his muscles to hold himself together.

Severe lack of stamina, unable to school for more than ten minutes without tiring.

Excessive spookiness, which I've seen reported by other people but isn't necessarily a recognised symptom, I'm not sure.

His reaction to a high oil, high vitamin E, rda selenium diet was fairly conclusive because of the improvement he showed, but the lack of strength and stamina continued to be a big issue. He sat down when I attempted to hack him down a neighbouring field, for example.

I put him on alcar and there was a marked improvement in all symptoms. He also packed on muscle like it was going out of fashion, and grew at least an inch and a half in three months. To all intents he is now a normal five year old, though immature mentally.

For anyone who wants to try it, alcar is available at around 30 a kilo on ebay. Dose is 10-15g per day. I feed in only one feed.

the symptoms are about a third of the way down the page. One of the symptoms it states is that they appear normal afterwards as opposed to tying up.

I thought your horse had PSSM? What makes you think he has HYPP as well if he has responded well to the PSSM diet? I don't think it works for HYPP horses as they need low potassium? I don't know much about HYPP hence my curiosity. The symptoms you describe are all PSSM symptoms in my experience - and if he was negative for PSSM with the tail hair test (which tests for type 1 only) he could easily be PSSM type 2 or another similar muscle myopathy which would need to be diagnosed by biopsy if you wanted to know (not really necessary if he has responded to the diet tho).

My horse is 12years old, has always " frozen " in stressful/exciting situations. Not spooky at all, very bold and brave. Never shown any signs as a youngster but out hacking when anticipating coming home , narrow gateways , having to walk slower than she wishes freezes. When I said freezes she will NOT move at all. Only small movement in her head mainly looking left , and towards hind end. Has got dramatically worse over the last 2 years. Tires easily in the school and finds schooling hard. Hacking is impossible , freezing constantly on the way back unless I keep her in trot , but then she can start to sidestep and if I slightly try to halt her takes smaller and smaller steps to then go stiff and stop. How ever , if I get off she will move forward no problem at all. Same in the school, if work becomes too tough she goes stuffy and freezes. Recently this has become so much worse that she is unridable. 2 weeks ago, she was so bad that she fell whilst I was hacking luckily both unharmed apart from small scrape on her leg. Have done a small amount of research on hyPP and behaviour is very similar in some respects. She has always been very weak behind and always used front end a lot more than needed. Lots to say but hard behaviour to describe! Certainly not tying up as will freeze for up to 20 mins and then happily walk off like nothing's happened. Same with going out to shows etc if she gets too much can take her back to Lorry load her and it's as if she hadn't even got off!

I thought that was just the American name for EPSM, because of the reference to Impressive, who I thought passes on EPSM? Sorry if I've got that all mixed up :(

I'm no expert but HYPP is another not very nice muscle disorder which affects QHs and it does come from a horse called Impressive. PSSM/EPSM does not come from Impressive (well not particularly, I'm not entirely sure if he is implicated in spreading PSSM as well!) and is an across the board disorder affecting QH, draft horses and probably many other horses.

Both disorders are horrendous and good on anyone who makes sure their horse is tested prior to purchase and *definitely* prior to breeding.
