Hereditary Hemochromatosis

Hereditary hemochromatosis (HH) is an autosomal recessive disorder of iron metabolism resulting in excess iron storage in the liver, skin, pancreas and other organs. Early diagnosis and treatment is essential in avoiding clinical complications of diabetes, liver cancer, cardiomyopathy and cirrhosis of the liver. Molecular genetic confirmation of this condition is an integral part of the diagnostic process when evaluating a patient for hereditary hemochromatosis. HH is associated with the HFE gene located on chromosome 6p21. There are two well-described mutations, C282Y (n845G>A) and H63D (n187C>G), are known to be associated with hereditary hemochromatosis and are evaluated in this test.

Reasons for Referral

  • Confirmation of a diagnosis in an individual with suspected hemochromatosis.
  • Carrier testing for at-risk relatives.

Testing Methods

A select region of the HFE gene is amplified from patient genomic DNA via polymerase chain reaction (PCR). The PCR product is analyzed by restriction fragment length polymorphism (RFLP) studies.
