Question on AQHA Registration Paper

[AHorseSomeDay]

I was looking at my horse's AQHA paperwork and it says HYPP results = N/N.

What does this mean? Is this good or bad?

Thanks.

That's a good thing. It means your horse does not have HYPP.

[My Two Cents]

From the AQHA Handbook

http://www.aqha.com/association/registration/pdf/registrationrules_09.pdf

(1) The following notification shall be placed on registration
certificates of foals descending from the stallion Impressive or
any other bloodline determined to carry the HYPP gene:
“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.”
When the parent(s) tracing from the HYPP line has tested negative
for HYPP with an appropriate designation appearing on their registration
certificate, the above notification is not required, and will,
instead, be substituted by the designation “N/N”; or, after testing
negative for the gene, the notification may be substituted by the designation
“N/N” upon request of the owner at his or her expense.
(2) Mandatory testing for HYPP. At such time as AQHA
requires mandatory parentage verification of any foals to be registered
in either the numbered or appendix registry, (see 202(i)) any foal tracing
to bloodlines known to carry the HYPP gene shall be tested for
HYPP at the time the genetic testing for parentage is performed. The
results will be designated on the registration certificate in lieu of the
above notification. Such testing will not be necessary if the foal’s closest
ancestors, tracing to the HYPP line, have been tested negative and
designated on their registration certificates, these foals will automatically
be designated “N/N” on their registration certificate.
(3) Effective with foals born on or after January 1, 2007,
all descendants of the stallion Impressive, AQHA registration number
0767246, shall be required to be parentage verified and HYPP
tested, subject to the conditions in (c)(2) above. Any foal testing
homozygous positive for HYPP (H/H) will not be eligible for registration
with AQHA.

So Yes, N/N is good

This is HYPP, a very serious inheritable disease:
