If I were the owner of registered purebred Arabian that had beed diagnosed
with HYPP I would take a REALLY close look at my horse's pedigree and try
to find out where it was in error (since no p.b. arabian should be a
decendent of a QH).
As I said, unless new discoveries have been made about HYPP, any
registered p.b. Arabian that has the trait is not really a p.b. arabian
at all...and somebody falsified a breeding report somewhere along the line.
HYPP is quite prevalent in the QH, Appaloosa, and Paint registries (all
of which allow the use of QH bloodlines in their stud books), but I have
never heard of an Arabian having it.
