Tyrosinemia, Type II (TYR-II)


Tyrosinemia, Type II (TYR-II) is an inborn error of metabolism, an inherited condition in which an enzyme, tyrosine aminotransferase, is either missing or not working well. Tyrosinemia Type II is considered an amino acid condition because people with TYR-II are unable to break down an amino acid (part of protein), known as tyrosine, when this enzyme is not working properly. Tyrosinemia Type II can affect the eyes, skin, and/or intellectual development.
