Every horse should be treated as PSSM possible. Some horses carry a dominant copy and some carry a recessive copy. I've see horses with total "suspect" lines be N/N and horses with a bunch of no names carrying a copy. |

Location: California | The issue is the majority of these big time "suspect" names are long gone so there's no way to test them and truly isolate the main contributors. |

This site will show you if a horse is positive or suspect for a few genetic diseases, obviously it's not perfect as not all horses are added if the information has not been provided or found.

PSSM is not a recessive gene. If they have it, it's dominant. It's not like GBED. |

Unfortunately the only recessive muscle myopathy is being called P5. It's only in draft animals. It has not been found in any light riding or TB animals that they have said YET. But we know the stock horse breeds came from a bunch of different types of horses, so never say never.
The different muscle myopathies are coming from different bloodlines (P2 variants are from mostly race horses) they have suspects but nothing definite unless a son or daughter tests homozygous positive for something. Then you know both of their parents have the gene. That's about all we can do at this point. Because you know they aren't going to test some of these big name stallions to find out. |

I apologize I didn't word it correctly, I meant sometimes carries 1 copy and sometimes carries 2 copies - but you are absolutely correct it is not recessive

Location: Oklahoma | The stud that I looked up was Oklahoma Fuel. and I didn't know if P2/*P2 meant he has PSSM2?
Also it is showing that he has a couple PSSM1 in his background.
Bully Bullion shows RedBlk=E, Agouti+A, Status+Ref What does this mean? and also looks like PSSM1
So if you have a horse out of these two should you test? These are grandparents. the mom and dad doesn't pull up. This horse belongs to friend of mine that I will be riding for awhile and I want to help this horse as much as I can. Not sure if test will be done if need to because he doesn't belong to me. He is gelding so no worries on breeding.
Thanks for the help, Also, I was trying to find the original thread on PSSM from way back when, can someone please help me find I know it was super long thread!

Location: Peg-Leg Julia Grimm | "Bully Bullion shows RedBlk=E, Agouti+A, Status+Ref What does this mean?" This is his color genetics. He was bay so he had to be at least one copy of black with at least one copy of agouti.
"and also looks like PSSM1" I would be surprised if he was P1. In his pedigree many of the horses are TB so they list PSSM1 and they have TB* (Thoroughbred) but behind it they have n/n (negative/negative) which means because they are TB, they will not have P1. They haven't found any P1 in full blooded thoroughbreds to date. There are many TB's that have P2 variants though. They list Special Effort as a P2 suspect.

Location: Peg-Leg Julia Grimm | As far as what to do. Does he have any issues now? If not, I would feed him exactly like the former owners did or whoever has been feeding him while he has been symptom free. Or someone could pay for a P2 variant test which is $249 and takes several weeks.
If it were me and he's symptom free, I wouldn't try to fix what isn't broke. If he is showing symptoms then study up on the P2 diet and switch him over to that. There are several variants and they all require slightly different diets but they all require a good quality protein and balanced minerals. You may have to experiment with different things. If I were you, I'd join the PSSM Forum on facebook to ask them what is the best starting point.

*P2 means the horse carries the pssm2, they just cannot determine if N/P2 or P2/P2. |

Oklahoma fuel has a foal that tested P2/P2 and n/PX. Meaning Oklahoma fuel HAS TO carry at least one gene of the P2, and a good possibility he also carries PX (they don't know if the foal got it from sire or dam). |

My gelding was n/P3 PX/PX...he had to be put down. |

You're right. They are using P2, P3, P4 and Px as working names for the other non-PSSM variants. They are not the same as the sugar storage problem with PSSM1 horses and they are not the same as each other as far as what causes them. I'm sure we will all need to learn new terms when the scientific community finally names the mutations. |

| Yep, my mare is n/P2 and PX/PX and unridable going on 3 years and shes only 7 :( and VERY well bred with big names on her papers...definitely prevalant and something to be aware of come breeding time or when buying a prospect. I know there are a lot of lines I will stay away from now. |
