Clinical Classification

Clinical Information

  • Tyrosinemia

    an autosomal recessive inherited metabolic disorder caused by mutations in the fah, hpd, and tat genes. it is characterized by deficiency of one of the enzymes that are involved in the metabolism of tyrosine. it results in elevated blood tyrosine levels and accumulation of tyrosine and its byproducts in the liver, kidney, nervous system and other organs.

  • Tyrosinemia Type I|Type I Tyrosinemia

    tyrosinemia caused by mutations in the fah gene. it is characterized by deficiency of the enzyme fumarylacetoacetate hydrolase. it is the most severe form of tyrosinemia. signs and symptoms appear early in life and include failure to thrive, vomiting, diarrhea, jaundice, and bleeding tendency. it may result in liver and kidney failure. patients with this type of tyrosinemia may also have a predisposition for hepatocellular carcinoma.

  • Tyrosinemia Type II

    tyrosinemia caused by mutation(s) in the tat gene, encoding tyrosine aminotransferase. the inheritance is autosomal recessive.

Patient Education


Metabolic Disorders

Metabolism is the process your body uses to get or make energy from the food you eat. Food is made up of proteins, carbohydrates, and fats. Chemicals in your digestive system break the food parts down into sugars and acids, your body's fuel. Your body can use this fuel right away, or it can store the energy in your body tissues, such as your liver, muscles, and body fat.

A metabolic disorder occurs when abnormal chemical reactions in your body disrupt this process. When this happens, you might have too much of some substances or too little of other ones that you need to stay healthy. There are different groups of disorders. Some affect the breakdown of amino acids, carbohydrates, or lipids. Another group, mitochondrial diseases, affects the parts of the cells that produce the energy.

You can develop a metabolic disorder when some organs, such as your liver or pancreas, become diseased or do not function normally. Diabetes is an example.

Footnotes

[1] Not chronic - A diagnosis code that does not fit the criteria for chronic condition (duration, ongoing medical treatment, and limitations) is considered not chronic. Some codes designated as not chronic are acute conditions. Other diagnosis codes that indicate a possible chronic condition, but for which the duration of the illness is not specified in the code description (i.e., we do not know the condition has lasted 12 months or longer) also are considered not chronic.
