Lavender Foal Syndrome (LFS)

Lavender Foal Syndrome (LFS) is an inherited lethal neurologic disorder known to affect Arabian foals and named for its characteristic expression of a dilute coat color. LFS is a recessive genetic disorder where newborn foals have problems standing, often after a difficult birth. Clinicial signs include seizure-like limb rigidity, hyperextension of the head, neck and spine (opisthotonus) and involuntary movement of the eyeballs (nystagmus). All affected foals are usually euthanized within days after birth. VetGen has licensed the direct DNA test for detecting LFS from Cornell University.
