HYPP

HYPP stands for Hyperkalemic Periodic Paralysis. It is a genetic disease of descendants of Impressive.

Some things I want to say about HYPP:

1. Not all descendants of Impressive have it. I had a very, very nice mare with him in her lines and she was N/N.

2. Just because a horse has never exhibited symptoms of HYPP does NOT mean they don't have it and they never will experience symptoms. There are a lot of horror stories out there of horses that have never experienced symptoms suddenly having a fatal attack.

3. There is a VERY simple solution to this problem. DON'T BREED HYPP POSITIVE HORSES. Not even if they're H/N. I saw an ad for a very gorgeous little paint filly that was HYPP H/H the other day. The owners were giving her away and not only were they not willing to pay for their mistake, they also suggested her being a nice halter prospect broodmare.
