If CSNB is connected to particular Appaloosa coat patterns, would CSNB be considered a genetic risk factor associated with that coat pattern?
Not exactly – the amount of patterning on the body was not the determining factor. The type of patterning is what matters. Coat patterns that indicate the presence of two dominant copies of LP are associated with CSNB. Referring to Diagram 1 earlier in this document, you will see that fewspot, near-fewspot, large snowcap, moderate snowcap and small snowcap horses are represented, all the way down to horses born with no white patterning at all. These horses are all night blind, all equally affected. The amount of white patterning they display is not important, except that when they have moderate to large amounts of patterning, they are easier to classify correctly as being homozygous for LP. Horses homozygous for LP born with no coat patterning are night blind.
