Looking at a 4 yr old.

allbreedpedigree says his sire is n/p1 for PSSM.

id like to verify that and see if he was tested when registered.  Owner is not sure so I’m trying to see if I can check or tell her how to check.

my understanding is n/p1 could still be symptomatic?  

You can call AQHA and ask for 5 panel results. All Breed is not very accurate 

Thanks, I wonder how long I’ll sit on hold, lol.

i didn’t figure allbreed was accurate, but wanted to make sure I could check it out.  The original one I was asking about actually had his on the back of his papers.  I have another one to look into though 

If you're a current AQHA member you can check 5 panel results with a couple of the free reports available online. Both of the Master Registration reports include test results.

To answer your question about N/P1 being symptomatic, yes they can be, as it is a dominate gene, not recessive like HERDA and GBED, which you need two copies to be symptomatic. 

We have a PSSM n/P1 horse, non symptomatic nor was her mother, no matter the routine or diet.  What I have learned, from a FB group, there are many more layer to P1 then people realize, same with P2.  I also feel this page a lot of the posters over react and make up symptoms, again it is still new to me.  Further testing can be done for various varients.  I've also been told it's not IF but WHEN and our horses mother is in her early/mid 20's symptom free to this day,

I am in no way promoting PSSM but it can be easily managed with diet, have a friend who has symptomatic horses but not confirmed and with diet change it's managed 100%, and believe the real severe cases are the P1/P1 or P2/P2.

Thanks!  Last time I tired to log into the new system it wouldn’t let me.  Looks like they’ve made some progress there.

Doesn’t look like the mare has been tested.  Her sire is all negative, but it doesn’t look like there’s any results on the mare’s side.
