title: [Lysosome enzyme pseudodeficiency].
abstract: Inherited deficiency of lysosomal hydrolase often displays different clinical features. However, a greatly reduced enzyme activity may be observed in healthy individuals. This pseudo-deficiency concerns at least nine lysosomal hydrolases. When a deficiency has been proved, the presence of mutations known to cause pseudodeficiencies must be searched, above all in Tay-Sachs disease and metachromatic leukodystrophy.
