Evaluation of the differential diagnosis of hyperammonemia and hereditary orotic aciduria
When orotic acid is measured after a protein load or administration of allopurinol, excretion of orotic acid is a very sensitive indicator of ornithine transcarbamylase (OTC) activity. An allopurinol challenge may be helpful in determining whether a female patient may be a carrier of an OTC mutation if molecular genetic testing was not informative.
