Tyrosinaemia Type 1
Tyrosinaemia Type 1 is a rare metabolic disorder characterised by raised levels of the amino acid, tyrosine in the blood. The disorder occurs when there is an absence or a deficiency of an enzyme known as fumarylacetoacetate hydrolase which is needed to break down tyrosine. If this amino acid is not broken down there is an accumulation of tyrosine breakdown products in the body especially the liver, the kidneys and the brain. Individuals with this condition present with either an acute or a chronic form. The forms are based on the age of the child and the severity of his or her symptoms.
Approximately one in every 100,000 babies in the United Kingdom is born with this condition.
