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 کاملNewborn screening for hepatorenal tyrosinemia: Tandem mass spectrometric quantification of succinylacetone.
BACKGROUND False-positive and false-negative results occur in current newborn-screening programs for hepatorenal tyrosinemia, which measure tyrosine concentrations in blood spots, sometimes in combination with other metabolites, including succinylacetone. We present our experience with a newly described method for succinylacetone quantification in routine newborn screening. METHODS Succinylac...
متن کاملMetabolic studies in a mouse model of hepatorenal tyrosinemia: absence of perinatal abnormalities.
Radiation induced chromosomal deletions at the albino locus in the mouse, lethal when homozygous, cause abnormalities of expression of several unlinked liver specific genes. Recently, the gene encoding FAH was shown to be included in the deletions. Since in humans FAH mutations cause tyrosinemia type I, deletion homozygous mice were suspected of having tyrosinemia. Studies of plasma amino acids...
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 کاملHepatorenal syndrome.
Hepatorenal syndrome is a common complication in patients with advanced cirrhosis and ascites characterized not only by renal failure but also by marked alterations in systemic hemodynamics and vasoactive systems. Renal failure is due to a marked hypoperfusion of the kidney secondary to renal vasoconstriction. The pathogenesis of hepatorenal syndrome is not completely known but it is thought to...
