Xanthinuria
SpecialtyEndocrinology Edit this on Wikidata

Xanthinuria, also known as Xanthine oxydase deficiency is a rare genetic disorder causing the accumulation of xanthine.

It was first formally characterized in 1954.[1]

Causes

It can be caused by a deficiency of xanthine oxidase, which is an enzyme necessary for converting xanthine to uric acid. [2]

Presentation

Sufferers have unusually high concentrations of xanthine in their blood and urine, which can lead to health problems such as renal failure and xanthine kidney stones, one of the rarest types of kidney stones.

Treatment

There is no specific treatment beyond maintaining a high fluid intake and avoiding foods that are high in purine.
