Hepatorenal tyrosinemia
In 1957 Sakai and Kitagawa in Japan reported the clinical and biochemical findings in a patient with tyrosinemia, tyrosyluria, liver cirrhosis, and renal rickets. Subsequently, reports were published from various countries of other patients with hepatorenal tyrosinemia (HRT). 4-Hydroxyphenylpyruvate dioxygenase deficiency was originally proposed as the cause of HRT. However, in 1977 Lindblad et...
متن کاملAnimal models of tyrosinemia.
Hereditary tyrosinemia I (HT I) is a genetic disorder of tyrosine metabolism characterized by progressive liver damage from infancy and by a high risk for hepatocellular carcinoma. HT I is due to mutations in the fumarylacetoacetate hydrolase (Fah) gene, which encodes the last enzyme in the tyrosine catabolic pathway. Disturbances in tyrosine metabolism lead to increased levels of succinylaceto...
متن کاملTyrosinemia Type1: A case report
Tyrosinemia type 1 is an inherited metabolic disorder attributable to deficiency of fumarylacetoacetate hydrolase enzyme. Here we report an eight month-old male Saudi infant who presented with jaundice, fever, and disturbed level of consciousness accompanied by abdominal distension, hepatomegaly and ascites with features suggestive of rickets. The diagnosis of tyrosinemia typ 1was confirmed bas...
متن کاملTyrosinemia type III in an asymptomatic girl
Tyrosinemia type 3 (HT3) is a rare inborn error of tyrosine metabolism caused by mutations in the HPD gene encoding 4-hydroxyphenyl-pyruvate dioxygenase, which is transmitted in an autosomal recessive trait. The disorder is characterized by tyrosine accumulation in body fluids and massive excretion of tyrosine derivatives into urine (www.orpha.net). Since it is the least frequent form of tyrosi...
متن کاملEnhancing newborn screening for tyrosinemia type I.
Hepatorenal tyrosinemia, also known as tyrosinemia type I (Tyr-I) is an autosomal recessive inborn error of metabolism. The primary enzyme defect has been attributed to a deficiency of fumarylacetoacetase (EC 3.7.1.2) (1 ). Tyr-I is usually asymptomatic in newborns, but if left untreated it affects liver, kidney, bone, and peripheral nerves; in its most severe form, affected infants may die fro...
