Frame overo including Lethal White Syndrome

Why test for frame overo?

Frame overo markings include eye-catching white patches, and often a white face accompanied by one or two blue eyes. The amount of white on a frame overo horse or pony can be highly variable, from a very discrete patch of white on the belly all the way up to majority white coat colours.

Frame overo is unique amongst white coat colour patterns in that foals born with two copies of the frame overo gene suffer from the heart-breaking and fatal Overo Lethal White Syndrome. Testing helps breeders avoid crosses that could produce Lethal White Syndrome foals.
