Tyrosinemia Type 1
National Organization for Rare Disorders, Inc.
It is possible that the main title of the report Tyrosinemia Type 1 is not the name you expected.
Tyrosinemia type I is a rare autosomal recessive genetic metabolic disorder characterized by lack of the enzyme fumarylacetoacetate hydrolase (FAH), which is needed for the final break down of the amino acid tyrosine. Failure to properly break down tyrosine leads to abnormal accumulation of tyrosine and its metabolites in the liver, potentially resulting in severe liver disease. Tyrosine may also accumulate in the kidneys and central nervous system.
Symptoms and physical findings associated with tyrosinemia type I appear in the first months of life and include failure to gain weight and grow at the expected rate (failure to thrive), fever, diarrhea, vomiting, an abnormally enlarged liver (hepatomegaly), and yellowing of the skin and the whites of the eyes (jaundice). Tyrosinemia type I may progress to more serious complications such as severe liver disease, cirrhosis, and hepatocarcinoma if left untreated. Treatment with nitisinone and a low-tyrosine diet should begin as soon as possible after the diagnosis is confirmed.
