White cell enzymes
Genetic defects of lysosomal enzymes cause the accumulation of incompletely catabolised substrates, with consequent accumulation in the affected cell systems, eg. connective tissue, cartilage, solid organs, bone and, above all, nervous tissue.
Investigation of suspected lysosomal storage diseases.
