Milloin Sabino1-geeni löydettiin?
Sabino 1 was identified in 2005 by researchers at the University of Kentucky. The Sabino 1 gene, and the associated spotting pattern, is found in Miniature horses, American Quarter Horses, American Paint Horses, Tennessee Walkers, Missouri Fox Trotters, Mustangs, Shetland Ponies, and Aztecas. SB1 is notably absent from the Arabian horse, Thoroughbred, Standardbred horse, Shire horse and Clydesdale. There are many proposed genes responsible for the sabino-like white spotting in these and other breeds. Researchers gave the allele they discovered the name "Sabino 1" with the expectation of finding genes yet to be named "Sabino 2", "Sabino 3", and so on. However, the next allele to be discovered on KIT caused a dominant white phenotype, and so was given the name W1. After that, all other alleles found at the KIT locus were given names in the W series, even the ones that would better be described as sabino than dominant white. As a result, it is unlikely that a Sabino 2 will ever be named. If more sabino alleles are found in the future, they will most likely be given names in the W series.
