Fumarylacetoacetase is an enzyme that in humans is encoded by the FAH gene.[1][2][3]

This gene encodes the last enzyme in the tyrosine catabolism pathway. FAH deficiency is associated with Type 1 hereditary tyrosinemia (HT).[3]

Fumarylacetoacetate hydrolase is an enzyme which catalyzes the hydrolysis of 4-fumarylacetoacetate into fumarate and acetoacetate.


Mutations in the FAH gene cause type I tyrosinemia.
