Five Negative Splashed White Test Results

I am going to start a Negative Splashed White Test Results area here in hopes that we can all learn from these as well. We only had SW-2, or SW-3 Negative results on all ten tests. So they are not noted seperatly. [b]Magic Mans Color Prints[/b] Bay Frame Sabino Overo Pinto Stallion, with Blue Eyes. Homozygous for Black. Color Prints was tested at UC Davis and found to be a Bay, Frame (LWO) pinto, Homozygous for Black, Sabino (SB1) gene. Negative for the Silver Gene at Animal Genetics. [b]Results from UCD: Negative for Splashed White SW-1 [/b] [img]http://pacificpintos.com/referencesires/images/magicman12.jpg[/img] [b]Comment: Two blue eyes and bald face, maximum white frame sabino. [/b]************************************************************************************************************************ [b]Canterbury All That Jazz[/b] Jet Black Homozygous Tobiano Pinto Stallion Jazz was tested and was found to be homozygous for Tobiano.

She has sabino type roaning, no roan on either parent. Has had many foals and no roan foals. Perhaps another type of sabino that we cannot test for?

Very interesting. It seems to me that minis could have another type of SW, they still fit the phenotype for the most part.

Daylene Alford Fri, 01/27/2012 - 10:59

Well, 2 of the three have frame which is known to cause blue eyes and also face white but even so we have 2 test results so far of a horse with blue eyes and neither frame nor one of the 3 testable splash mutation. Very interesting stuff.

I am not convinced Frame does cause blue eyes- we have discussed this before.
We have a lot of Splash in UK Shets but no Frame and loads of blue eyes on solids.
I am completely sure there are more Splash genes that have yet to be mapped.

Here is another photo of Cross Country Blue Moon, the Blue Eyed Buckskin above showing his facial markings and eye color.

Again, I have never tested him for sabino as I just did not see it.

As a reminder: Blue Moon tested Homozygous for the Tobiano Pinto gene, and negative for the Frame Overo (LWO) gene.

Does anyone think I am missing anything?

Comments??

Lethal white foals all have blue eyes. Since it causes blue eyes in the homozygous foals, I have no trouble with it causing blue eyes at times with lesser levels of expression.

Katie Fri, 01/27/2012 - 21:36

The only thing that surprises me about these results is the negative on the blue eyed boy. None of the markings suggest splash to me, so this just helps affirm the picture I have of splash.

It may be easier for me to accept the idea of more types of Splash genes AFTER I see some examples of SW2 and SW3. So far, everything I have seen is SW1.

Threnody Sat, 01/28/2012 - 13:09

Neat to find another blue eyed non LWO or SW1,2,3 horse. I'm really hoping UC Davis might be interested in testing the 2 of them. I also want to see the SW2 and SW3, but we may have to wait until someone's QH and Paint happen to be from those unreleased lines.

I'm also convinced frame can and does cause blue eyes because of the lethal white foals as admin stated.

Threnody Sat, 01/28/2012 - 17:54

And splash can cause blue eyes in one dose. Frame and blue eyes is also highly correlated. Again not enough to prove either of our opinions 100%.

Interesting, it just tells me there are more SW yet to map though. Were SW2 and 3 the ones they thought could cause blindness? Not surprising there isn't heaps of them so far then? I also don't think frame causes blue eyes, or face white for that matter, as said though I guess we can't really prove it either way. So far nothing positive seems to be UK based breeds? Be interesting if any of the welshies, shetlands etc. test positive for SW. I'll test my Gypsy Cobs and a few shetlands if I think it would be worth doing. I'd like to see at least one proper UK breed prove SW1 is out there first though LOL!

Ok, now you are really getting me confused. :-t I know a lot of Welsh that if they test negative, I WILL consider this test worthless. ~x(

Splash is linked to deafness, not blindness.

Sorry, I meant to say deafness :ymblushing:

Is there anyway that the positive test results with photos could be put together as a reference page and the same with the negative test result horses, without all the comments???

It would be grand to have all the reference material in one location.

I think pages of comments distract from the use of the reference material.
