HYPP question....

Okay guys I am still learning and reading daily etc about this new world of horses I have been delightfully brought into/back into by my darling daughter and her horse, but reading about impressive and his disorder I have found lots of research... If the horse is out of impressive bloodline and has been tested HYPP N/N, is it possible that they could still pass the disorder onto their offspring? How far out would it be safe to breed off of an impressive bloodline? I know this sounds like a crazy question but was just wondering, looking at gettin my other daughter a horse, she is also starting to fall in love with them... And also looking at breeding possibly in the future...

Since he's N/N he won't pass it on... so you should be safe

H/H - This status means that a horse carries a double copy of the defective gene and will pass at least one copy of the gene and the disease to 100% of it's offspring.

N/H - This status means that the horse carries one normal gene and one HYPP gene and statistically an N/H horse will pass the gene and the disease to 50% of it's offspring when bred to a N/N or non-Impressive bred horse. N/H to N/H cross will statistically result in 25% N/N progeny, 50% N/H progeny, and 25% H/H progeny.

N/N - This status means that the horse carries two normal genes. It does not have the disease, nor can it be passed on.

If you are looking at Quarter horses, Paints or Appalosas I would pay to have the test done no matter what the breeder/seller tells you. I hate to say you can't trust horse people, but when it comes to this and other health issues some are pretty liberal with the truth. Good luck and hope all your daughters are horsewomen

Thanks for the advise. I am just getting bogged down with info. I thought that it was not able to be passed on with a n/n result just wasn't sure I was reading all info correctly. Starting to believe that taking care of a horse is harder and more demanding than raising children. Lol.not really but It does seem to be more info to learn though.

I think I remember reading somewhere that it was on their registration papers.

Foals born in 1998 and later tracing to IMPRESSIVE will have the following statement placed on their Certificate of Registrations:

"This horse has an ancestor known to carry HYPP, designated under AQHA rules as a genetic defect. AQHA recommends testing to confirm presence or absence of this gene."

Beginning with foals born January 1, 2007 and after, all descendants of IMPRESSIVE, #0767246, must be parentage verified and HYPP tested unless their decendant parent has already been tested and found to be N/N. Any foal that tests H/H will not be eligible for registration.

The APHA has no such requirements or rules.

BTW, our "Lady" (left in the picture) has Impressive in her bloodline.
