The pathophysiology and treatment of hereditary tyrosinemia type 1

Grompe, Markus·2001·Seminars in Liver Disease

Abstract

The topic of this review is hepatorenal tyrosinemia (hereditary tyrosinemia type 1 [HT1], or fumarylacetoacetate hydrolase deficiency; OMIM# 276700). HT1 is the most serious and common of the genetic defects in tyrosine degradation. In addition, this disorder has importance as a model of spontaneous self-correction of liver disease, as a model of liver repopulation by transplanted cells and gene therapy, and as a genetic cause of hepatocarcinoma. However, other forms of hypertyrosinemia exist; hence, the differential diagnosis also will be described briefly. Recent years have seen much progress in our understanding of the molecular basis, the pathophysiology, and especially the treatment of HT1. The current intervention with 2-(2-nitro-4-trifluoro-methylbenzyol)-1,3 cyclohexanedione (NTBC) therapy has improved the outcome of this once devastating disorder. The successful repopulation of the HT1 liver with transplanted cells and positive results in the use of gene therapy in animal models may someday lead to therapy in humans that will obviate the need for life-long dietary and pharmacological therapy.

Statistics

Recomputing p-values needs the paper’s full text.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • When a FAH deficiency exists, toxic metabolites such as fumarylacetoacetate accumulate in hepatocytes and renal proximal tubules causing death in a cell-autonomous manner.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
