Cystinosis is an inherited condition in which the body accumulates the amino acid cystine (a building block of proteins) within the cells. Excess cystine forms crystals that can build up and damage cells. These crystals can negatively affect many systems in the body, especially the kidneys and eyes. There are three distinct types of cystinosis: nephropathic cystinosis, intermediate cystinosis, and non-nephropathic or ocular cystinosis. All three types of cystinosis are caused by mutations in the CTNS gene and inherited in an autosomal recessive pattern.^[0]
