A rare genetic disorder due to a lack of parahydroxyphenylpyruvic acid oxidase, which catalyzes the conversion of tyrosine to homogentisic acid. Characterized by elevated blood and urine levels of tyrosine, liver damage, mental retardation, and rickets.
An inborn defect of metabolism of the amino acid tyrosine causing excess excretion of parahydroxyphenylpyruvic acid in the urine, giving it abnormal reducing power.
