The protein encoded by this gene is an enzyme in the catabolic pathway of tyrosine. The encoded protein catalyzes the conversion of 4-hydroxyphenylpyruvate to homogentisate. Defects in this gene are a cause of tyrosinemia type 3 (TYRO3) and hawkinsinuria (HAWK). Two transcript variants encoding different isoforms have been found for this gene.

GeneCards Summary for HPD Gene
HPD (4-Hydroxyphenylpyruvate Dioxygenase) is a Protein Coding gene. Diseases associated with HPD include Tyrosinemia, Type Iii and Hawkinsinuria. Among its related pathways are Biosynthesis of cofactors and Histidine, lysine, phenylalanine, tyrosine, proline and tryptophan catabolism. Gene Ontology (GO) annotations related to this gene include oxidoreductase activity, acting on single donors with incorporation of molecular oxygen and 4-hydroxyphenylpyruvate dioxygenase activity. An important paralog of this gene is HPDL.
