• Dysphagia

  Slow eating and dysphagia are common. Heterozygotes may have elevated levels of free cystine in leukocytes. The later onset juvenile form of cystinosis presents with kidney failure secondary to glomerular damage instead of tubular dysfunction. [disorders.eyes.arizona.edu]

  These include myopathy and dysphagia due to the accumulation of cystine in the muscles, endocrine involvement such as hypothyroidism and diabetes mellitus, hepatomegaly, hypersplenism and photophobia from the accumulation of cystine in the cornea. [sjkdt.org]

  Finally, the ocular form is observed in adults, usually asymptomatic and may only present photophobia. The diagnosis of cystinosis is confirmed by determining the cystine content in leukocytes. [tellmegen.com]

  As the disease progresses, cystine crystals deposit in the cornea of the eye causing significant pain and sensitivity to light (photophobia). 2 Juvenile or late-onset nephropathic cystinosis is generally diagnosed in childhood or adolescence. [avrobio.com]

• Kidney Failure

  The kidney disease leads to a Fanconi syndrome type pattern of kidney failure. Pancreatic insufficiency, ovarian failure, myopathy, and central nervous system signs are often seen. [disorders.eyes.arizona.edu]

  If left untreated, children with this condition typically develop kidney failure within the first 10 years of life. With treatment, end-stage renal failure is often delayed. One of the most notable symptoms in infants is failure to thrive. [healthline.com]

  Without specific treatment, most children with cystinosis will later develop kidney failure before the age of ten requiring dialysis or a kidney transplant. [cystinosis.org.uk]

  Malfunctioning kidneys and corneal crystals are the main initial features of this disorder. If intermediate cystinosis is left untreated, complete kidney failure will occur, but usually not until the late teens to mid twenties. [en.wikipedia.org]

  "The late-onset or adolescent form of cystinosis accounts for about 5% of cases and is very under-recognized," he said. This form typically presents between 10 to 12 years of age but may occur in late adolescence or early adulthood. [raredr.com]

  This is very important in delaying the onset of renal failure and other complications in cystinosis. [wjgnet.com]

  The re is a milder form with onset in adolescence [MIM*219900] and one with onset in adulthood without kidney damage [MIM*219750]; the latter two forms are thought to be allelic to the nephropathic form of early childhood. [cystine + G. [medical-dictionary.thefreedictionary.com]
