Is Appaloosa-specific CSNB connected to a particular coat pattern?
The 2005-06 study by Sandmeyer et al revealed that CSNB is associated with Appaloosa coat patterning of a specific type. Appaloosas with coat patterns indicating they are homozygous for LP are affected. The above diagram shows these patterns. Appaloosas that are heterozygous for LP are not affected by CSNB. Horses that are true solid non-characteristic Appaloosas, with no dominant copies of LP, are not affected by CSNB either. For more information on the research that was done to establish this connection, readers will want to read the summary of the research paper, or the entire document (see below on this page). More information relating to coat pattern and CSNB can also be found on the Frequently Asked Questions and Inheritance of CSNB pages.
