Help with HYPP

Thanks to all the wonderful people on this forum, I found out about HYPP I've heard about it before but was unaware it was also known as the Impressive Syndrom. My mare has Impressive in her 5th generation. She only has it on her dad's side, and she's clear on her mom's side (thank goodness). The person I bought her from never disclosed any information about her being HYPP N/N, N/H, H/H. I read Fancy's story and that just broke my heart. Vega is also 4 and I can't even imagine losing her. Does anyone have a horse out of Impress Me Shanon that was tested for HYPP?

Appy, can you just test her to be on safe side? I don't think it's very expensive (I may be wrong though)....

I went onto a webiste, paid the $50 and pulled out mane hair. I will send it out tomorrow or monday, depending when the post office is open (i know monday, but hoping sunday). I've been reading a lot about HYPP, and am praying she doesn't have it. My boyfriend thinks her chance of having it is 10%, but I know there's a 50% she does. I will keep everyone updated.

I can tell you what signs Fancy had although at the time I didn't realize what they were. I always thought she was just a laid back horse (one of the reasons I bought her) She would almost fall asleep when being tacked up and then start to fall over. I would just give her a nudge and she would be ok. She drug her back feet a lot, just walking across the pasture I noticed she wasnt picking up her feet. I thought she was depressed, we got another horse to keep her company but it didn't help. She was very trippy on the trail, I figured she was just a clutz. Now that I know what HYPP is and the signs of an attack I can see that this is what was happening. Her grandfather was Impressive. I fault the AQHA and the other registrys for not doing something sooner to stop this defect. They could have wiped out this disease in a single generation and did nothing. I admit there are genetic defects in many breeds of horses but not many that can kill the horse and rider. Not in the least break our hearts when a beloved companion suffers an attack.

Vega is the spirited type. She's always on the move, unless its time to eat. There was one time during the summer when I went to see her that she was just like standing in the stall, head lowered and just seemed very out of it. My boyfriend and I thought it was heat stroke, or the beginning of it since she is out from 8am-4pm in direct sunlight. I hosed her off and she seemed fine. I don't know if that was an episode, but there hasnt been anything since. There is one thing tho, I started teaching her to jump, with ground poles and small cross rails, and one time we were jumping, she did it fine, but as a I rounded a turn, she had a funky step. It's like her leg buckled but she caught herself. I immediately got off and walked her so it could see her legs move. She's done that a few times when I graze her, but I didn't think it was anything. When I see her today, I'm going to take a video and post it, so you can get a better idea on how she moves.

I was up til about 3:30 yesterday reading all about HyPP, trying to get as much information as possible and just learn about it. Someone at my barn mentioned to me that her horse and my horse are related because they both have Impressive in their show name and I thought it was pretty cool, but not anymore. I have to ask if she got her horse tested, because some of the things i've read where it was just out of the blue really really scared me

Information is your best ally. I think if we knew then what we know now we maybe could have saved Fancy. I hate to think that way because it makes me sad, but there it is. Fancy was out in the heat on the fourth of July. We always wondered if it was someone throwing firecrackers out the car window (we live on a road that goes to a lake) or something like that that brought on the stress.
I pray that your test results are negative.

Thank you Vidaloco, I do too. I'm going to call her previous owner, the one who bred Vega's mom to Impress Me Shanon and ask if she got her tested. I finally found her number online and an ad about her and no where does it say anything about HyPP which makes me a little suspiscious. Just as an FYI, I didn't get her from her previous owner, I bought her from the barn where I ride. Nice of them to tell us anything about her.

Appy, let us know the results. Hope, she's is NOT positive!!
    09-24-2007, 12:40 PM
Don't worry Kitten, I'll post her results. I don't know what I'm going to do while I wait for the results. I'm going to be a mess, that's for sure.

I talked to Vega's old owner and they never got her tested because "she never had any symptoms, so I never bothered". Kind of sucks, but I'm glad I sent it out anyways. I should know by either the end of this week, or early next week. I'll post an update once I get her results.
