Hereditary hemochromatosis (HH) diagnosis has changed due to HFE gene discovery. This review covers HFE's role in iron regulation and molecular iron storage, impacting iron toxicity and tissue damage.

Area of Science:

  • Medical Genetics
  • Molecular Biology
  • Biochemistry

Background:

  • Hereditary hemochromatosis (HH) is an iron overload disorder.
  • The HFE gene mutation is a primary cause of HH.
  • Understanding iron homeostasis is crucial for HH diagnosis and treatment.

Purpose of the Study:

  • To review the role of the HFE gene in iron absorption and transport.
  • To explore the molecular mechanisms of iron storage in HH.
  • To discuss the impact of iron deposit forms on toxicity and tissue damage.

Main Methods:

  • Literature review of HFE gene function in iron metabolism.
  • Analysis of molecular aspects of iron storage proteins (ferritin, haemosiderin).
  • Comparison of iron deposit characteristics in different iron overload conditions.

Main Results:

  • HFE mutations disrupt iron homeostasis regulation.
  • Iron storage involves various chemical forms (ferrihydrite, goethite).
  • Iron deposit type, location, and disease influence toxicity and treatment.

Conclusions:

  • HFE gene discovery has revolutionized HH diagnosis.
  • Molecular understanding of iron storage is key to managing iron overload complications.
  • Tailoring treatment based on iron deposit characteristics may improve outcomes.
