WebCystine Chemical Pathology Notes Cystinuria is caused by a defect in cystine transport in the kidney. Cystine accumulates in the urine, which can lead to crystals and ultimately renal stone formation. Around 1 in 2000 people in the UK are affected by cystinuria. It is an inherited condition. WebCystinuria, a genetic disorder of cystine transport, is characterized by excessive excretion of cystine in the urine and recurrent cystine stones in the kidneys and, to a lesser extent, in the bladder. Males generally are more severely affected than females.
