PW121990 View Pathway	disease Tyrosinemia Type 3 (TYRO3) Rattus norvegicus Tyrosinemia type 3, one of the three types of tyrosinemia, is a rare disorder with only a few reported cases. Tyrosinemia type 3 results from a defect in the HPD gene which codes for 4-hydroxyphenylpyruvate dioxygenase. 4-Hydroxyphenylpyruvate dioxygenase plays a role in the catabolism of tyrosine by catalyzing the conversion of 4-hydroxyphenylpyruvate to homogentisate. A defect in this enzyme causes tyrosine and phenylalanine to accumulate in the blood resulting in increased excretion of tyrosine in the urine. Tyrosinemia type 3 symptoms include: seizures, mental retardation and intermittent ataxia (occasional loss of balance and coordination).

PW000182 View Pathway	disease Tyrosinemia Type I Homo sapiens Tyrosinemia type I, also known as fumarylacetoacetase or FAH deficiency, is the most severe type of tyrosinemia, a buildup of tyrosine in the body. It is caused by an autosomal recessive mutation in the the FAH gene that encodes for fumarylacetoacetase, an enzyme that is responsible for the last of five steps that are involved in the metabolic breakdown of tyrosine in the liver and kidneys. The lack of this enzyme's function leads to a buildup of 4-fumarylacetoacetic acid as it couldn't be broken down to fumaric acid and acetoacetic acid. This also leads to an increased concentration of maleylacetoacetic acid. This eventually leads to the increased concentration of L-tyrosine in the body. Symptoms of tyrosinemia type I include jaundice and an enlarged liver, kidney dysfunction, as well as a failure to grow, as foods with high protein and amino acids lead to increased symptoms. Additionally, individuals are more at risk for future liver cancer.

PW121815 View Pathway	disease Tyrosinemia, Transient, of the Newborn Mus musculus A transient defect in tyrosine metabolism is a common aminoacidopathy in the premature and full-term human infant. This disorder, termed neonatal tyrosinemia, was first described by Levine and Gordon in 1939. In the intervening years other workers have studied this disorder, and have noted the concurrence of tyrosinemia and tyrosyluria. In a current survey of 15,000 infants, 6 mild tyrosinemia occurred during the first week of life in 10% of full-term infants, and severe tyrosinemia occurred in approximately 30% of premature infants. The enzymatic basis of neonatal tyrosinemia is complex and involves the susceptibility of p-hydroxyphenylpyruvic acid oxidase to inhibition in the presence of its substrate, p-hydroxyphenylpyruvic acid and derivatives. The inhibition is reversible by removal of excess substrate and by reducing agents such as ascorbic acid, 2, 6-dichiorophenolindophenol, and a number of hydroquinone and phenylenediamine compounds.
