The clinical aspects of adult hexosaminidase deficiencies.
The authors describe the clinical phenotypes of hexosaminidase deficiencies (GM2 gangliosidosis). The symptoms, differently combined, include cerebellar ataxia, motor neuron disease, dystonia, psychosis, neurovegetative troubles with different severity. Morphological changes are evident in rectal, muscle or nerve biopsies. Minor clinical changes are described in carriers from a family. A chronic GM2 gangliosidosis has to be suspected in any atypical case with the above-mentioned symptoms with autosomal-recessive inheritance.

Movement disorders associated with chronic GM2 gangliosidosis. Case report and review of the literature.
A 24-year-old man presented with dystonia, dementia, amyotrophy, choreoathetosis, and ataxia. Partial hexosaminidase A deficiency was documented in serum and leukocytes and confirmed by rectal biopsy with ganglion cells containing membranous cytoplasmic bodies. A brief review of the literature reveals that tremor, dystonia and choreoathetosis are common but neglected symptoms associated with chronic GM2 gangliosidosis.

Juvenile progressive dystonia: a new phenotype of GM2 gangliosidosis.
A 10-year-old boy developed progressive dystonia and dementia. His symptoms had begun at age 2 1/2 years, and he had been unable to walk by 8 years. At age 10 he was severely dystonic, unable to use his hands to feed himself, and almost anarthric . He had dysphagia and urinary incontinence, and functioned at a 4-year-old level of mental development. The mean percentages of beta-hexosaminidase A measured in serum, leukocytes, and fibroblasts by the heat denaturation method, each on three separate assays, were 5.9, 9.8, and 13.0%, respectively. These values are higher than in Tay-Sachs disease but are similar to levels seen in late-onset or adult cases of GM2 gangliosidosis. This patient appears to represent a new phenotype of juvenile GM2 gangliosidosis having dystonia as the dominant symptom.
