"Lavender foal syndrome is a heritable and fatal neurologic disease that is primarily found in Egyptian Arabians. Affected foals have a characteristic soft lavender, pale pink, or silvery coat color.

Based on research performed by Samantha Brooks, PhD, an assistant professor in the Department of Animal Science at Cornell University, and colleagues, a mutation in a particular region of the gene called myosin Va (MYO5A) is responsible for LFS.

"Approximately 10% of the Egyptian Arabian population carries the mutation," explained Brooks. "If two carriers are bred, there is a chance the foal will have LFS. This condition is passed on via a recessive inheritance pattern, which means that there is a 25% chance that a foal will have LFS if two carriers are bred."

The LFS syndrome test identifies the mutant gene in DNA extracted from either hair roots or whole blood."

The LFS test is offered through Cornell University's Animal Health Diagnostic Center and costs $47.00 USD.
