Textbk. Med. I. ix. 99/2 Cystinosis is not related to cystinuria; confusion has arisen in the past because the generalized amino aciduria, which is a component of the Fanconi syndrome induced by cystinosis, includes cystine and this amino acid was more easily detectable than most others before chromatographic methods became available.
