Pedigree Analysis is limited to the info we have on hand at the time.
When we give someone an analysis of their pedigree we look at the pedigree and see if there are any nn (negative horses in the pedigree (we can then rule that line out). Then we look to see if there are any positives in the pedigree and then we look if there are any horses with positive foals. (A horse with a positive foal is not necessarily positive as the foal may have gotten the positive gene from the other side of his pedigree) and finally we look to see there are any suspects.
Obviously if a horse has 2 nn parents we can declare the foal as nn as well.
But if a horse has as an eg. two n/P1 parents - we can not declare that foal to be positive. Even if both parents are n/P1 the foal can still have a chance to be nn - so we can never guess, based on pedigree alone if a horse is going to be positive - all we can do is highly recommend testing.
There are two cases where we might guess a horse to be positive - one with 98% accuracy and one with about 70% accuracy.
Case 1 - a parent is homozygous for a genetic defect - eg. P1/P1 - the foal will automatically inherit a P1 gene - the only margin for error here is if the parent's result was recorded wrong.
Case 2 - a parent is n/P1 and a the foal has list of obvious PSSM1 symptoms. Margin for error here is that PSSM2 symptoms are very similar to PSSM1 - so the foal has a 50/50 chance of being P1 but it could be nn and positive for PSSM2 - further pedigree analysis looking for PSSM2 suspects can help increase the odds of this prediction to being more accurate.

The database is only as good as the info is accurate.
In an effort to verify pedigrees we ask that, as an AQHA member, if you have purchased any sire or dam details for any AQHA horses and you wouldn't mind sharing them with us - please email to foals@manitobahorse.com with AQHA detail in the subject line.
We are urgently seeking people who would be willing to donate $5 and be able to look up a $5 report at AQHA.
This is an exciting way to help us really start to nail down the source horses for PSSM1.
We have a list of about 20 key horses we are searching for reports on and you can help with a very small donation of time (takne to get the report) and $5. Please contact me if you would be willing to help out in this way.
Messaging Sharalee Worms on facebook is the best form of contact and will get the fastest response.

STATUS: if a horse is marked with a VREF that means the pedigree has been verified.
*** IF the horse has three stars after it's name *** it means the foal report is on file and all foals are in the database.
PF= Positive Foal, PGF = Positive Grandfoal, PGGF = positive great grandfoal, * means the horse is positive by default
CA= commona ancestor - BGP= Best Guess Positive - BGN Best Guess Negative - MLP=MOST LIKELY POSITIVE
these codes are internal codes used for establishing patterns and figuring out suspect horses
If you see a horse here with errors or your horse is on here and you would like it removed please send us a polite message and ask us to remove or correct it. Our intention is not to offend but to provide information and to research pedigrees.
