Neonatal Ataxia (NA), or Bandera's Syndrome (BNAt), is a genetic mutation that affects the nervous system of Coton de Tulear dogs. The mutation damages the cerebellum, the part of the brain that controls coordination and movement.
An affected Coton will tend to fall on its side when attempting to stand and will not be able to walk. The dog will only be able to move in sideways or "swimming" motions. Symptoms can be detected quickly after a pup is old enough to begin moving around. There is no treatment or cure, and affected dogs will never be able to properly walk.
Neonatal Ataxia is an autosomal recessive trait; both parents would need to be carriers of the genetic mutation in order to produce offspring with Neonatal Ataxia. Carriers will not exhibit any symptoms, but will pass on the defective gene to offspring. It is important to test a dog's DNA for BNAt before breeding, especially if breeding to another carrier.
