WebApr 22, 2016 · Cystinosis is the most common hereditary cause of renal Fanconi syndrome in children. It is an autosomal recessive lysosomal storage disorder caused by mutations in the CTNS gene encoding for the carrier protein cystinosin, transporting cystine out of the lysosomal compartment. WebSep 9, 2024 · Cysteamine is an aminothiol which reacts, in the lysosome, with cystine in a thiol-disulfide interchange reaction converting cystine into cysteine and cysteine-cysteamine mixed disulfide. This compound rapidly exits the lysosome through the lysin transport system [ 9 , 10 ].

People with cystinosis lack a functioning transporter (cystinosin) which transports cystine from the lysosome to the cytosol. This ultimately leads to buildup of cystine in lysosomes, where it crystallizes and damages cells. Cysteamine enters lysosomes and converts cystine into cysteine and cysteine-cysteamine mixed disulfide, both of which can exit the lysosome.
