Elevated orotic acid
WebSlightly elevated values are found in autismand other disorders. An analog of the Krebs cycle compound 2-oxoglutaric (alpha-ketoglutaric) acid. Elevated 3-oxoglutaric acid may correlate with low 2-oxoglutaric acid, possibly indicating an interference with 3-oxoglutaric acid in the Krebs cycle.
