Sensory neuropathy is an early-onset disease that causes degeneration of the sensory and motor nerve cells in the body.
FAM134B/RETREG-1
Autosomal recessive
Clinical signs of this disease start between two and seven months of age and can include progressive proprioceptive ataxia with intermittent knuckling of the paws, hyperextension of the limbs, and self-mutilation wounds in the distal part of the limbs. Typically, thoracic limbs are less severly affected than the pelvic limbs. The patient can present with decreased proprioception and nociception, as well as urinary incontinence.
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.
