Cystinosis, Nephropathic; Ctns

Description

Cystinosis has been classified as a lysosomal storage disorder on the basis of cytologic and other evidence pointing to the intralysosomal localization of stored cystine. Cystinosis differs from the other lysosomal diseases inasmuch as acid hydrolysis, the principal enzyme function of lysosomes, is not known to play a role in the metabolic disposition of cystine. The fact that plasma levels are well below saturation indicates that the defect is a cellular one. Within the cell, cystine is compartmentalized with acid phosphatase and is membrane-bound as demonstrated by electron microscopy. Ferritin accumulates in the same organelle which appears to be the lysosome.
