Cross-species summary: A lysosomal storage disease in which there is a buildup (storage) of mannose-rich compounds, due to the lack of the enzyme alpha-mannosidase, whose task is to cleave mannose from such compounds. Clinical signs include ataxia, head tremor, aggression, and finally paralysis and death.
