Sabino 1

Gene

Sabino 1 (SB1) is an incompletely dominant splice variant of the KIT gene that causes one form of sabino white. One copy usually gives white legs, a wide blaze and roaning or jagged white on the belly, though the amount varies and can be small; two copies give a white or nearly white horse that is viable. Many sabino-patterned horses do not carry SB1.

Horse Coat Color DNA Records: Save the Report Behind the Prediction
