We are taking a summer break from December 21 to January. You can still place orders now and while we are on break. If we we receive but don't finish testing your samples before Christmas they will be at the top of our list when we re-open in January. Samples that arrive during the break will be stored carefully for testing in January.
Thanks for all the testing you've sent us this year, and have a wonderful summer!
W34 white markings
Summary
W34 is a version of the KIT gene that is thought to cause relatively subtle white markings such as a blaze and socks. It produces larger white markings on red-based colours like chestnut. Like W20, it has a white-increasing effect when it is inherited in combination with other white marking genes, particularly sabino 1 and the other W genes.
W34 has been found in a number of horse breeds. The following are just some of the horse and pony breeds where some individuals have tested positive to W34: Arabian, QH, Paint, Warmbloods and Welsh
If your horse has a blaze and one or more socks, or perhaps a few white belly spots that have not been explained by other white marking genes, test for W34 as well as W20 and sabino 1.
