Dominant white is a variable white spotting pattern caused by many different mutations in the KIT gene. The VGL tests for the five most common mutations known as W5, W10, W13, W20, and W22. Homozygosity for W5, W10, W13 or W22 is thought to be non-viable.
Camarillo White is a dominant white coat color characterized by a completely white coat, mane, and tail, and is found exclusively in the Camarillo White Horse.
