Type III tyrosinemia is very rare. Mild intellectual disability, seizures, and periodic loss of balance and coordination are the most common symptoms. Diagnosis of type III tyrosinemia is with a newborn blood screening test. Urine and blood tests may also be done if the screening is abnormal. ...

Tyrosinemia Type 1 (HT1) is an autosomal recessive disorder caused by a defect in the enzyme fumarylacetoacetate hydroxylase in the tyrosine pathway. Implementation of nitisinone (NTBC) treatment has dramatically improved survival rate of individuals with HT1, yet recent reports on cognitive impairmen...

The published literature on tyrosinemia type III consists of only a few case reports. In this report, we present a patient with tyrosinemia type III, autism, and mental retardation. This patient's speech improved and his autistic symptoms lessened on a tyrosine-restricted diet, although his ...
Tyrosinemia type III (OMIM 276710) is an autosomal recessive disorder caused by the deficiency of 4-hydroxyphenylpyruvate dioxygenase (4-HPD). Few cases have been described with mental retardation or neurological symptoms. Recently it has been demonstrated that 4-HPD participates to nitric oxide (NO...
The genetic tyrosinemias, autosomal recessive disorders, are characterized by the accumulation of tyrosine in body fluids and tissues. There are three types of tyrosinemias: Types I, II, and III. Type I has a prevalence of about 1 in 100,000 newborns in the general population. Type III is...
