Hereditary Hemochromatosis — A New Look at an Old Disease

Pietrangelo, Antonello·2004·New England Journal of Medicine

Abstract

For many years, hereditary hemochromatosis was regarded as a clinically and genetically unique entity marked by a classic presentation consisting of diabetes, bronze skin pigmentation, and cirrhosis. In 1996, identification of “the hemochromatosis gene,” HFE, was reported; since then, several other iron-metabolism genes have also been identified. This article reviews the current understanding and management of hereditary iron-overload disorders.

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?

  • The HFE mutation leads to impaired formation of hepcidin and thus an iron deficiency phenotype of macrophages, whereas excessively absorbed iron is stored in parenchymal organs such as liver, heart, or pancreas.

    “The HFE mutation leads to an impaired formation of hepcidin and thus to an iron deficiency phenotype of MΦs, whereas excessively absorbed iron is stored in parenchymal organs such as the liver, heart, or pancreas.”

    From Macrophage defense mechanisms against intracellular bacteria (2015) · cites this paper as [201]

  • Individuals with insufficient hepcidin production suffer from iron-overload in the blood and hepatitis.

    “Conversely, individuals with insufficient hepcidin production, suffer from iron-overload in the blood, and hepatitis (Pietrangelo, 2004).”

    From The Role of Iron Regulation in Immunometabolism and Immune-Related Disease (2019) · cites this paper as Pietrangelo, 2004

  • HFE mutations, especially the homozygous C282Y substitution, result in type I hereditary hemochromatosis.

    “HFE mutations, especially the homozygous C282Y substitution, result in type I (AKA classical) hereditary hemochromatosis (HH) (Camaschella et al., 2002; Pietrangelo, 2004; Weiss, 2010)”
  • HH is characterized by reduced serum Hamp and increased duodenal absorption of iron via Dmt1 and Fpn1 despite progressive iron overload in parenchymal organs including liver, pancreas, and heart.

    “HH is characterized by reduced serum levels of the antimicrobial peptide Hamp (hepcidin) and increased duodenal absorption of iron via divalent metal transporter 1 (Dmt1) and ferroportin 1 (Fpn1) despite progressive iron overload in parenchymal organs including the liver, pancreas, and heart (Zoller et al., 1999, 2001; Bridle et al., 2003; Pietrangelo, 2004; Bardou-Jacquet et al., 2013).”
  • Hfe deficiency results in reduced Hamp production and increased serum iron levels.

    “Hfe deficiency results in reduced Hamp production and increased serum iron levels (Pietrangelo, 2004).”

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.
