Fanconi syndrome and cystinosis

Fanconi syndrome is a type of kidney disease. Fanconi syndrome is often the first sign of cystinosis. It may lead to:

  • The body losing important substances needed for good health
  • Needing to pee (urinate) a lot
  • Extreme thirst or dehydration
  • A softening or weakening of the bones, commonly called rickets

Eventually, cystinosis may cause damage that leads to kidney failure (also called renal failure), dialysis, and kidney transplant. Taking cystine-depleting therapy (CDT) regularly has been shown to delay harm to the kidneys.
