Tyrosinemia type 1 is a genetic disorder characterized by elevated blood levels of the amino acid tyrosine, a building block of most proteins. This condition is caused by a shortage of the enzyme fumarylacetoacetate hydrolase, one of the enzymes required for the multi-step process that breaks down tyrosine. This enzyme shortage is caused by mutations in the FAH gene. Symptoms usually appear in the first few months of life and include failure to thrive, diarrhea, vomiting, jaundice, cabbage-like odor, and increased tendency to bleed (particularly nosebleeds). Tyrosinemia type I can lead to liver and kidney failure, softening and weakening of the bones, problems affecting the nervous system, and an increased risk of liver cancer. This condition is inherited in an autosomal recessive manner. Treatment should be started as soon as the condition is diagnosed and includes a diet restricted in tyrosine and phenylalanine along with nitisinone, a medication that blocks the second step in the tyrosine degradation pathway.
MalaCards based summary : Tyrosinemia, Type I, also known as tyrosinemia type i, is related to tyrosinemia and glycine n-methyltransferase deficiency. An important gene associated with Tyrosinemia, Type I is FAH (Fumarylacetoacetate Hydrolase), and among its related pathways/superpathways are Metabolism and Viral mRNA Translation. The drug Nitisinone has been mentioned in the context of this disorder. Affiliated tissues include Liver, pancreatic islet and kidney, and related phenotypes are generalized aminoaciduria and splenomegaly Disease Ontology : 12 A tyrosinemia that has material basis in deficiency of the enzyme fumarylacetoacetate hydrolase resulting in an increase in fumarylacetoacetate which inhibits previous steps in tyrosine degradation leading to an accumulation of tyrosine in the body. OMIM® : 57 Hereditary tyrosinemia type I is an autosomal recessive disorder caused by deficiency of fumarylacetoacetase (FAH), the last enzyme of tyrosine degradation. The disorder is characterized by progressive liver disease and a secondary renal tubular dysfunction leading to hypophosphatemic rickets. Onset varies from infancy to adolescence. In the most acute form patients present with severe liver failure within weeks after birth, whereas rickets may be the major symptom in chronic tyrosinemia. Untreated, patients die from cirrhosis or hepatocellular carcinoma at a young age (summary by Bliksrud et al., 2005). (276700) (Updated 05-Mar-2021) UniProtKB/Swiss-Prot : 73 Tyrosinemia 1: An inborn error of metabolism characterized by elevations of tyrosine in the blood and urine, and hepatorenal manifestations. Typical features include hepatic necrosis, renal tubular injury, episodic weakness, self-mutilation, and seizures. Renal tubular dysfunction is associated with phosphate loss and hypophosphataemic rickets. Progressive liver disease can lead to the development of hepatocellular carcinoma. Dietary treatment with restriction of tyrosine and phenylalanine alleviates the rickets, but liver transplantation has so far been the only definite treatment.
