Lethal White Syndrome occurs for "OO" Overo horses, and is fatal. If a foal geno is rolled as OO, it will be marked unusable. With this in mind, it is possible for a breeding to fail completely if two LWS foals are rolled, and the slots will still be used up if this occurs.

Overview:

• Causes irregular white patterning that starts from the belly and/or center of the horse. Markings should have cutouts around the edges to cause irregularity of shape and sharp edges. Will not round outward.
• White generally spreads within the center area of the horse, creating a "frame" of color around it. The only areas on the body where it may cross to the other side of the horse are the crest of the neck and the belly (from behind armpit to just past groin).
• Can cause extensive and/or irregular face markings, generally bald faces with some cutouts. May cause badger face.
• Mane/Tail: White in mane where touching; will not affect tail, as it cannot cross/touch.
• Skin: Pink skin beneath white markings.
• Eyes: Blue (optional)

Range:

• Minimum: May be fully hidden if desired.
• Maximum: White markings on the vast majority of the body, not crossing the "frame" of the body except on the neck/belly. Significant white markings on the face and legs.
