DEFINITION:
- lysosomal storage disease
-
Any inborn error of metabolism having four characteristics: (1) a defect in a specific lysosomal hydrolase; (2) intracellular accumulation of the unmetabolized substrate; (3) clinical progression affecting multiple tissues and organs; (4) considerable phenotypic variation within a disease. All but two of the lysosomal storage disorders are of autosomal recessive inheritance. The term comprises the mucolipidoses, mucopolysaccharidoses, disorders of glycoprotein degradation, lipase deficiencies, ceramidase deficiency (Farber's disease), α-galactosidase A deficiency (Fabry's disease), lipidoses, and gangliosidoses. Called also "lysosomal enzymopathy" and "inborn lysosomal disease."
