Here is another problem with the LWO gene and it confuses people who don't think they have a frame overo. It is possible for sabinos and splashed overos, as well as apparent Tobianos, to carry lethal white. Most likely, it is because these horses have a frame overo in their pedigree somewhere that passed on the overo gene, but it is not showing up in the coat, as often happens with overo. It is recommended to test for lethal white to anyone breeding any overo or a horse that looks solid but has overo in its pedigree. A lot of people don't do this research.
