Answer 2

Hyperkalemic periodic paralysis is a condition , primarily in QH and spread to Paints and Appaloosas through the line of  Impressive (AQHA)     http://www.foundationhorses.com

Answer 3

Impressive -was born an Appendix American Quarter Horse, however earned his full AQHA registration in 1971. He was the 1974 World Champion Open Aged halter stallion, the first such World Champion in his breed, despite carrying only 48 halter points in total. He is famous for his highly successful progeny, having sired 2,250 foals. Nearly thirty of his offspring went on to be World Champions themselves.

However, the Impressive bloodline tends to have HYPP {Hyperkalemic Periodic Paralysis}. Impressive was a quarter horse sire that passed on the fatal HYPP gene to some of his foals. He was a champion halter horse but he should not have been bred. This caused the deaths of many young and good horses. Get your horse tested. If he is N/N, he doesn't have the gene. If he is H/N he is a carrier..This might only be possible in females though. Carriers do not express the symptoms but they should not be bred. If he is H/H..see if you can do anything to prevent this disease.http://www.vgl.ucdavis.edu/services/hypp...

Here's what Bill Brewer, AQHA President had to say about it.http://www.aqha.com/association/registra...

I currently own 3 mares who are Impressive bred but all 3 are N/N.
