What is Cystinuria?

Cystinuria is an inherited condition that prevents the body’s retention of certain amino acids from excretory pathways. The clinical effect of cystinuria occurs in the urinary system where these amino acids collect in concentrations that are much higher than normal. One of these amino acids named “cystine” can form solid crystals which group together to form rock hard cystine kidney stones. These stones are either passed by urination or removed by surgical intervention.


About the ICF

We aim to support a strong and growing group of patients, families, professionals, and friends by providing educational and health related resources to affected individuals worldwide. Furthermore, we aim to promote knowledge of cystinuria within the research and medical communities in order to reduce kidney destruction, renal impairment, and subsequent health, vocational, and economic impact.
