Succinylacetone

In hepatorenal tyrosinemia type 1 (HT1) tyrosine breakdown is impaired due to a deficiency in fumarylacetoacetate hydrolase. As a consequence, fumarylacetoacetate is converted into succinylacetone (4,6-dioxoheptanoic acid) which is elevated in HT1 patients. Since succinylacetone is unknown to occur in any other metabolic pathway, it is a specific diagnostic marker for the disease. It can be reliably measured in plasma, urine, amniotic fluid and dried blood spots.
