The subject and several males of his family present behavioural disturbances of an enduring type. An aminoaciduria was discovered in the subject and his father. [ncbi.nlm.nih.gov]

Affected individuals present with the displacement of optic lenses known as ectopia lentis, mental retardation, skeletal abnormalities, osteoporosis, and premature arterial disease. [wisegeek.com]

It usually presents with cystine stone formation in the kidneys; a quarter of patients experience symptoms in the first decade of life. [patient.info]

• Severe Osteoporosis

  Affected individuals may present with an enlarged liver, protein intolerance, hyperammonemia, an impairment of kidney function, severe osteoporosis, or structural changes in the lungs. [wisegeek.com]

• Dark Urine

  The three characteristic symptoms of alkaptonuria are the presence of dark urine, large joint arthritis, and darkening ears and other cartilage and collagenous tissues. [wisegeek.com]

Eleven studies have also been carried out in ten patients with stable renal failure before and during treatment with different metabolites of vitamin D. [ncbi.nlm.nih.gov]

Prognosis The prognosis of cystinuria is variable and depends on the level of renal function at the time of diagnosis and initiation of therapy, and the success of preventative measures and surgical management. [encyclopedia.com]

Prognosis Malnutrition and a low-protein diet increase morbidity. Attacks become less frequent with increasing age. [patient.info]

However, since the description of aminoaciduria in hyperparathyroidism, the literature has been divided concerning the etiology of aminoacidura in conditions associated with abnormal vitamin D metabolism because secondary hyperparathyroidism often occurs [ncbi.nlm.nih.gov]

It can equally result from defects in the renal tubular reabsorption of the same amino acids; and, in regard to this latter phase, etiology would include many types of renal injury caused by inborn errors of cell metabolism, toxic agents, or vitamin deficiency [jamanetwork.com]

The treatment goal is to prevent stone formation by lifelong alkaline diuresis. [wisegeek.com]

An early re-equilibration of the amino acid metabolism can prevent the risk of developing, at the adult age, certain anemias and other diseases (rachitism, mental handicap, urinary infections, conjunctivitis, stomatitis, a.o.). [ncbi.nlm.nih.gov]

Treatment and management Prevention The primary goal of treatment of cystinuria is prevention of existing cystine stones through non-invasive means. [encyclopedia.com]
