disease:Defects in CTNS are the cause of cystinosis [MIM:219800, 219900, 219750]. This autosomal recessive disorder results from defective lysosomal transport of cystine. The classical nephropathic form is characterized by renal failure at 10 years of age and other systemic complications. Milder phenotype exist such as intermediate cystinosis, with later onset of renal disease and benign or non-nephropathic cystinosis, with symptoms related only to corneal crystals and photophobia.,function:Thought to transport cystine out of lysosomes.,similarity:Belongs to the cystinosin family.,similarity:Contains 2 PQ-loop domains.,tissue specificity:Strongly expressed in pancreas, kidney (adult and fetal) and in skeletal muscle. Expressed at lower levels in placenta and heart. Weakly expressed in lung, liver and brain (adult and fetal).,
