An 11-year-old Japanese girl was diagnosed as having type 3 GM1 gangliosidosis by clinical symptoms and enzyme assay. She was the youngest among the patients with type 3 GM1 gangliosidosis whose clinical and neuroradiological findings have been documented. Clumsiness since early infancy and dystonia since early childhood which progressed slowly without mental deterioration and dysmorphism led us to the diagnosis of type 3 GM1 gangliosidosis. Genotype determination showed point mutation in exon 2 of the beta-galactosidase gene, which is common among the patients reported in Japan. T2-weighted MRI demonstrated bilateral symmetrical hypointensity in the putamen and globus pallidus. Single photon emission computed tomography using 99mTc-HMPAO showed bilateral hyperperfusion in the basal ganglia which decreased gradually during 1 year of observation. Twenty-two patients with type 3 GM1 gangliosidosis reported in the literature whose onset was at under 15 years of age were reviewed.
