gangliosidosis

 [gang″gle-o-si-do´sis] (pl. gangliosido´ses)
a lipid storage disorder marked by accumulation of gangliosides in tissues due to an enzyme defect. In generalized gangliosidosis, a hereditary defect in β-galactosidase causes accumulation of ganglioside GM1, resulting in mental retardation, hepatomegaly, skeletal deformities, and, often, a cherry-red spot. In tay-sachs disease, a defect of hexosaminidase A results in accumulation of ganglioside GM2.

gan·gli·o·si·do·sis

(gang'glē-ō-si-dō'sis),
Any disease characterized, in part, by the abnormal accumulation within the nervous system of specific gangliosides, for example, GM2 gangliosidosis, Tay-Sachs disease; caused by hexosaminidase A enzyme deficiency with accumulation of GM2 ganglioside.

gangliosidosis

(găng′glē-ō-sī-dō′sĭs)
n.
Any of a group of lysosomal storage diseases characterized by the abnormal accumulation of gangliosides in the tissues, especially within the nervous system.

gan·gli·o·si·do·sis

(gang'glē-ō-si-dō'sis)
Any disease characterized, in part, by the abnormal accumulation within the nervous system of specific gangliosides (e.g., GM2 gangliosidosis, Tay-Sachs disease), caused by hexosaminidase A enzyme deficiency with accumulation of GM2 ganglioside.

gangliosidosis

A disorder of GANGLIOSIDE metabolism resulting in accumulation of gangliosides in nerve tissue, especially in the lysosomes. Gangliosidoses are usually due to gene mutation causing an enzyme defect or deficiency. An example is TAY-SACH'S DISEASE.

Broad categories include MPS, [GM.sub.2] gangliosidoses, neutral glycosphingolipidoses, glycoproteinoses, mucolipidoses, leukodystrophies, glycogen storage diseases, disorders of neutral lipids, and disorders of protein transport or trafficking (22, 23).
Despite extensive variability in findings among studied patients, bilateral symmetric thalamic changes have been found to be an early, predictable finding that is probably specific to the [GM.sub.2] gangliosidoses, such as Sandhoff 's disease, and may be useful in determining whether to perform more specific investigations in infants suspected of having a neurodegenerative disease.
