lysosomal storage disease

(redirected from Lysosomal storage diseases, nervous system)

lysosomal storage disease

 
any inborn error of metabolism in which the deficiency of a lysosomal enzyme results in accumulation of the substance normally degraded by that enzyme in the lysosomes of certain cells. These diseases are further classified, depending on the nature of the stored substance, as glycogen storage diseases (glycogenoses), sphingolipidoses, mucopolysaccharidoses, and mucolipidoses.

lysosomal storage disease

n.
Any of various genetic diseases caused by a deficiency or defect in a specific lysosomal enzyme or in another lysosomal protein and resulting in the accumulation of undegraded macromolecules in the lysosomes.

storage disease

any metabolic disorder in which some substance (e.g. fats, proteins or carbohydrates) accumulates in certain cells in abnormal amounts; called also thesaurismosis, thesaurosis.

lipid storage disease
any disorder of cellular metabolism that results in accumulation of lipids in tissues, e.g. gangliosidosis, sphingomyelinosis, gaucher's disease, globoid cell leukodystrophy, metachromatic leukodystrophy. Called also lipidosis.
