Hello, I have a two years old aqha, I didn’t test him for the 5 panels, his SIRE is 5 panels n/n and his DAM ’ S SIRE is also 5 panels n/n. Does that make him also negative or should I test him? Could he be only a carrier? Thank you
If you don’t have a test on the dam herself, I believe you’d need to test him.
You’ve tested 75% of the pedigree. Yes, you need to test the horse (or his dam.)
Thank you, but if he s 75 per cent it means that he could only be a carrier of one of the 5 diseases or he could also have the signs of them?
If HYPP is one of the 5 then he could also have HYPP as N/H and have symptoms. My horse was N/H and still had symptoms. We were able to manage him but HYPP is a dominant disorder so you do not need 2 copies to have symptoms.
So yes you should test him. If you can get the Dam’s results or the Dam’s Dam’s results you may be fine with that and not need to test him.
If he’s a gelding, then you don’t have to test him since he can’t pass any genes along. If he is intact, then absolutely test him if you are going to breed him. If you just want to know for your own sake, to recognize and manage disease early on, then test him.
Here’s the run down from the AQHA on what a five panel test covers:
https://www.aqha.com/media/13951/genetic-disease-descriptions-1.pdf
This is what you’re worried about with the info you have (as long as you have a gelding?)
With respect to the autosomal dominant genetic diseases listed below (HYPP, PSSM, and MH), only one defective gene is necessary to express the genetic disease in question.
If your horses dam received one copy of any of those gene from HER dam, she could have passed that on to your horse and your horse would be affected. It only takes one HYPP, PSSM or MH gene to cause problems.
These are the ones you’re not really worried about (until your horse is a stallion–if he is, he could pass these on and have affected babies):
With respect to autosomal recessive genetic diseases listed below (GBED and HERDA), typically, two copies of an abnormal gene (two copies = a pair) must be present in order for the horse to show signs of the genetic defect in question.
One HERDA gene or one GBED gene won’t cause problems for your horse.
So yeah, you still need to run a five panel on your horse, or his dam.
ok thank you, i knew from the owner that the dam has been tested only for HYPP because she has impressive line…
I’d be testing for MH and PSSM1 and PSSM2 if I was buying now. You would have to check, but it might be as cost effective to do the 5 panel and add on the PSSM2 as doing the 3 separately.
If he’s HYPP nH, or carries a PSSM1 gene, then his diet needs to be properly managed, gelding or not.

Which is why I went on to say, “If you just want to know for your own sake, to recognize and manage disease early on, then test him.” FYI, you can’t mess with some diseases, and you really should follow through with your vet if you suspect something like that. Don’t try to manage it using unverified information from anonymous internet posters.
My apologies, I shouldn’t have been quick-reading and posting that late.

It’s always good to go to sources that have a compilation of the facts and management of diseases like this. But I guarantee those places as “unverified” as any, will have way, way more and better information than most vets, simply because of the sheer number of horses owned by the people participating. I bet there are a great many vets who don’t know what PSSM is, let alone that there are 2 types, let alone possibly subtypes of Type 2. So take “go to your vet” for these things with as much of a grain of salt than “unverified information from anonymous internet posters”
There is little that is black and white with these diseases. The generic information is easily out there - high fat/low NSC (type 1), high protein/low NSC (type 2), and keep potassium below about 1.5% total (HYPP). Beyond that? It’s art as much as it is science as to what manages a given horse based on his individuality. And for that. a great many “anonymous internet posters” tend to have a lot more practical application than most vets. So don’t discount them either. You are also an annonymous internet poster who has given plenty of advice here, including feeding.

@Palm Beach - My vet and my trainer didn’t know that HYPP was dominant. Both thought it was recessive. There I didn’t have him tested before I bought him. He only had Impressive on one side pedigree so we figured he could only be N/H so no big deal. Yes he was N/H and eventually developed symptoms.
The vet didn’t know anything about managing the diet. We are in an area this is predominantly English sports and the Impressive bred horses are not common in my area as they do not generally fit the image most riders are looking for. I had to do the research on my own to determine the correct diet and management of my horse. My trainer randomly switched feed on me one time. She didn’t check the potassium. She checked the sugar though. ??? I guess she thought it was like diabetes. Many vets don’t know about some of these diseases. Some because they are not common in the horse population they treat, some because we have gotten a better understanding and awareness of these diseases since they graduated and that is not an area they did their continuing education in.

AQHA has been requiring testing for HYPP for all Impressive descendants since something like 2007. And your horse is 2? He must not be registered.
I guess you missed this.
tl; dr: The dam has been HYPP tested. The sire has been five panel tested. The OP is asking if she needs to five panel test her horse.
5-panel testing requirements only apply to stallions.
That’s why only the sire and damsire have been tested in this scenario.
The horse wouldn’t have needed to be tested for HYPP if both parents are tested n/n. So assuming you have registration papers, and he has not been tested, then he is n/n by way of both parents being n/n. And his papers would say n/n.
REG109.3.2 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, per REG102.8 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 (parents), 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
Well, he s aqha and nrha registered, the owner of the mare told me that the dam was tested for hypp
