General information
Sabino is a general description for a group of similar white spotting patterns. The sabino pattern is described as irregular spotting usually on the legs, belly and face, often with roaning around the edges of the white markings. A mutation has been discovered that produces one type of sabino pattern, it has been named Sabino1 as it is not present in all sabino-patterned horses. The Coat Colour Sabino 1 test, tests for the genetic status of the KIT gene. This gene has two variants (alleles).
Clinical features
The allele SB1 is semi-dominant. One copy of the SB1 allele results in horses with broken Sabino markings and possibly only a small amount of white. Two copies of the SB1 allele result in at least 90% white, also referred to as Sabino-white. The allele N is recessive and does not have an effect on the basic colour.
Additional information
More mutations will probably exist that account for other sabino patterns.
