Sabino is a white marking that spreads from the underside of the body, specifically from three areas: the throat, the elbow area, and the stifle area.
Sabino has jagged, speckled edges.  Minimal Sabino has crisp, clear edges, but higher-coverage Sabino causes Roan-like lightening and gradual edges.
As Sabino spreads, it remains more dense/extensive on the underside of the body.
Sabino causes irregular spreading of face markings, and can create bald face markings.

Genotype: Sb_
Locus:  Sabino is a KIT gene mutation, along with Roan, Tobiano, and Dominant White. A horse may carry only two KIT gene mutations.

• Coat: Sabino is a white marking.
• Mane and Tail: Mane will be white where marking touches. Gradients or white roots are acceptable.

Range:

• Minimum: Sabino can be hidden entirely.
