Roaning in Thoroughbreds?

Is there such a trait? I went to look at a JC registered TB mare yesterday and she had the strangest roaning looking pattern on the inside of her right hind leg.

It was more prominent at the coronet band and then kinda faded out up near the stifle. It definitely doesnt look like scarring of any sort since its not concentrated in one area, its pretty spread out. I guess it could be a birthmark of some sort, but I was thinking about it and I have never seen a TB with roaning.

FYI-she is solid bay with a few white hairs for a star and that's it.

I have one picture, its not a close-up of the roaning, but you can see a TINY bit of what I am talking about. Look at the right hind near the coronet band. In the picture, it looks like shine from the coat, but that's actually white hairs mixed with the bay...

Thoughts?

Lots of horses have odd roaning areas here and there.

There are a VERY FEW RARE TBs that are true/classic roan, but this girl is not one of them.

I have seen a couple of roan TBs. Here is a really old thread I made asking about the TB I owned at the time roaning, and somebody posted some good explanations as well as a picture of a road TB: Roan TB?

FYI-just for explanation purposes...I was not saying that she was a roan TB...I said she had an AREA that resembled roaning...

Thanks for the link QH!

TB's do have Sabino and Rabicano roaning. That is not to be confused with a true roan though.

Thank you...

She is for sure not a true roan, hands down.

I just have never personally seen a roaning type pattern anywhere on a TB, which is why I was curious.

Hopefully I will be picking her up on Thursday and I will be able to get a good close up shot of the area where the "roaning" is.

This is the closest to true roaning I could find on a thoroughbred

I think it is possible that it is just her sock. I've seen a few horses, although not TB's have a sock that is partially roaned out and not a full sock.

I see what your saying. We had a tb that had the same roaning patterns. As he aged it got more and more too.

*facepalm* I meant to comment on the roan sock.

Kind of looks to me like there was trying to be a sock there, but the mare has a white suppression gene which isn't quite wiping it out. Kind of the same idea when a horse has ermine spots on a sock.
