Neurodegenerative Vacuolar Storage Disease (Lagotto RomagnoloType)



Test Overview:

Affected dogs suffer from progressive cerebellar ataxia, sometimes accompanied by episodic nystagmus and behavioral changes.


Nervous system / Neurologic - Associated with the brain, spinal cord and nerves


Autophagy related 4D cysteine peptidase (ATG4D) on Chromosome 20

Variant Detected:

Base Substitution c.1288G>A p.Ala430Thr


Moderate. This disease can cause significant signs of discomfort and/or dysfunction in affected animals. It may involve relatively high treatment/management costs, and can sometimes reduce life expectancy.

Mode of Inheritance:

Autosomal Recessive
