  • Lavender foal syndrome (LFS), is an autosomal recessive genetic disease that affects newborn foals of certain Arabian horse bloodlines. Affected LFS foals have severe neurological abnormalities, cannot stand, and require euthanasia shortly after birth.
  • Severe Combined Immunodeficiency (SCID) is an autosomal recessive disorder that affects the Arabian An affected foal is born with no immune system, and thus generally dies of an opportunistic infection, usually within the first four to six months of life
