I adopted a paint PMU mare that was bred to a stallion that we later
found out carried the lethal white gene. Fortunately my mare turned
out to not be in foal, but anyone breeding paints should know that the
lethal white is NOT just confined to the overos...
From a UC Davis article that can be found at
http://www.vetmed.ucdavis.edu/ceh/HR20-3lethal.html:
"The lethal white disease is most often associated with the overo
spotting pattern in horses, but it can occur in tobianos and toveros as
well.
Horses with this disease are all white and die shortly after birth due
to intestinal abnormalities (similar to Hirschsprung Disease in
humans). Surgical intervention has not proved successful; therefore,
this condition is lethal in all cases."
The whole article is quite good.

Jean, You are right about it being Overo that produces the lethal
white. Howerver, it can happen to any that carry the overo gene. A
friend had a crop out mare (QH who had too much for the QH registry at
that time) woh had only one white spot on her belly. She had a lethal
white when bred to an overo stallion. When I bred my breeding stock
mare to an overo stallion I kept my fingers crossed! I lucked out!
