A lysosomal storage disease, belonging to the group of oligosaccharidosis or with a wide clinical spectrum that is divided into two main clinical subtypes: sialidosis type I, the milder, non dysmorphic form of the disease with characteristics of gait abnormalities, progressive visual loss, bilateral macular cherry red spots and myoclonus, that presents in adolescence or adulthood (second or third decade of life); and sialidosis type II (see this term) the more severe, early onset form, with characteristics of progressive and severe mucopolysaccharidosis-like phenotype with coarse facies, visceromegaly, dysostosis multiplex, and developmental delay. Bilateral macular cherry red spots are also present. Sialidosis type II has been further divided into congenital (with hydrops fetalis), infantile and juvenile presentations.

A rare disorder characterized by early-onset progressive encephalopathy with migrant, continuous myoclonus. Three cases have been reported. The focal continuous myoclonus appeared during the first months of life. Prolonged bilateral myoclonic seizures and generalized tonic-clonic seizures occurred later. Subsequently, a progressive encephalopathy with hypotonia and ataxia appeared. Cortical atrophy was revealed by computed tomography (CT) scan and magnetic resonance imaging (MRI). The etiology is unknown.	Is a	True	Myoclonic disorder	Inferred relationship	Some
