Leukodystrophy in Dogs

Category: Nervous System & Behavioral
Breeds documented: 1
Published sources: 6

Overview

White matter contains nerve fibers coated with myelin, an insulating material that speeds nerve signals. Leukodystrophies are inherited disorders that damage this tissue. One form linked to the TSEN54 gene has been described in Standard Schnauzer puppies. It causes severe, worsening problems with movement and brain function very early in life. Other forms have different genetic causes and patterns, so this puppy disorder does not describe every case.

Signs to watch for

Unsteady walking with exaggerated steps
Walking in circles
Holding the head tilted to one side
Trembling during movement
Seizures

In the TSEN54-related Standard Schnauzer form, signs appeared shortly after birth or before four weeks of age.

Emergency Go to an emergency vet now if your puppy has a seizure.

Diagnosis and tests

Vets combine the history and neurological examination with brain imaging to investigate a suspected white matter disorder. An MRI scan can show the areas affected, but the pattern needs to be considered with other findings. For Standard Schnauzers, testing for the associated TSEN54 variant can help identify this particular inherited form.
