Disease overview

Sensory ataxic neuropathy is an inherited neurological condition that causes degeneration of the nerves in the body. It is characterized by uncontrolled muscle movement, abnormal posture, and decreased spinal reflex.

Gene name

tRNA-Tyr (MT-TY)

Inheritance

Mitochondrial

Signs and symptoms

Clinical signs are early-onset when an affected dog is a puppy. These include difficulty walking, a hard time maintaining normal posture, and abnormal, uncoordinated movements (ataxia).

How is it diagnosed

A veterinarian will conduct a thorough exam, including a review of health history and any clinical signs. Neurological tests, including imaging, may be required for a definitive diagnosis. Genetic testing is necessary to determine if there is an underlying genetic cause, which can assist veterinarians with diagnosis and help breeders identify affected and carrier dogs.
