when breeding an N/H horse to an N/N horse, the foal has a 50% chance of getting the genetic disease. An N/H horse with HYPP can have symptoms ranging from small muscle tremors, to full blown attacks where their entire body is seizing. Some horses will dunk their head in water to try to find some relief (From sudden rise in temperature, or just pain I don't know). These attacks if severe enough, can lead to death. HYPP horses require a special diet that helps them from having these attacks. Not every N/H horse will show symptoms, but it's horrible for the ones that do.
That was pretty much my version of a general description. To find out more information, you can Google HYPP and a whole load of sources will pop up. PSSM is also a good one to have knowledge of, as that's becoming more and more prevalent in breeding stock horses. PSSM causes 'tying up' and some lameness issues. I would want to know the full 5 panel test results for all these horses (For me, if I was ever to breed, both mare and stallion would have to be genetically clear on the 5 panel. )
