BACKGROUND First considered as a polymorphism of the HFE gene, the H63D mutation is now widely recognised as a haemochromatosis associated allele. But few H63D homozygotes with clinical manifestations of hereditary haemochromatosis (HH) have been reported. Concurrently, an increasing number of genes have been shown to interact with HFE in iron metabolism. AIMS To describe the clinical

It is the main iron overload disorder. Hemochromatosis is notorious for having symptoms that are often initially misattributed to other diseases. Heterozygous C282Y mutation Heterozygotes of the C282Y mutation represent a small proportion of patients with hemochromatosis.

Individuals who are heterozygous for C282Y or homozygous for H63D are not affected with HH but often have subclinical elevated iron levels. 8-10 They may also have an increased risk of developing neurodegenerative disorders. 11-13

Hemochromatosis may not be recognized until later in life. Patients are usually asymptomatic but may present with a variety of signs and symptoms. The HFE H63D is a single-nucleotide polymorphism in the HFE gene (c.187C>G, rs1799945), which results in the substitution of an aspartic acid for a histidine at amino acid position 63 of the HPE protein (p.His63Asp). HFE participates in the regulation of iron absorption. There is no predictable risk of iron overload in people with one copy of the H63D gene alteration, and without the C282Y gene alteration.

Heterozygous C282Y (1 in 5) At no increased risk of developing Hereditary Haemochromatosis associated iron overload. Is a carrier of Hereditary Haemochromatosis. If iron overloaded, other causes of iron overload should be considered. Heterozygous H63D At no increased risk of developing HH associated iron overload.

The genetic test does not need to be repeated when iron studies are requested in the future. Put on the biochemistry request form “genotype known”. 2001-06-01 2001-07-01 2007-03-02 2001-05-02 This test is direct DNA-based detection by PCR of a common mutation in the HLA-H gene that causes hereditary hemochromatosis, a common iron overload disorder. C282Y heterozygotes are reflexed to H63D for an additional charge. C282Y heterozygous; H63D homozygous; H63D heterozygous; C282Y/H63D compound heterozygous . Reference value is normal, meaning that the hemochromatosis gene was not detected.
