A study of 3,011 unrelated white Australians found that 14% were heterozygous carriers of an HFE mutation, 0.5% were homozygous for an HFE mutation, and only 0.25% of the study population had clinically relevant iron overload. Most patients who are homozygous for HFE mutations do not manifest clinically relevant haemochromatosis (see Genetics ...
The protein encoded by this gene is an integral membrane protein that is similar to MHC class I-type proteins and associates with beta-2 microglobulin (beta2M). It is thought that this protein functions to regulate circulating iron uptake by regulating the interaction of the transferrin receptor with transferrin.
Majority of the cases of hemochromatosis are caused by mutations in the HFE (Homeostatic Iron Regulator) gene. [17] Type 3 HH is characterized by compound heterozygote mutations in both transferrin receptor 2 (TFR2) and HFE, i.e. a single mutation in each gene. HFE is located on chromosome 6 and TFR2 is located on chromosome 7.
This mutation is associated with diverse health issues, however H63D syndrome is the only known specific expression of a homozygous HFE-H63D mutation to date. The homozygous HFE-H63D mutation is the cause of classic and treatable hemochromatosis in only 6.7% of its carriers. [25] H63D syndrome is independently a distinct entity, and the ...
Iron overload (also known as haemochromatosis or hemochromatosis) is the abnormal and increased accumulation of total iron in the body, leading to organ damage. [1] The primary mechanism of organ damage is oxidative stress, as elevated intracellular iron levels increase free radical formation via the Fenton reaction.
Clinically, most cases of hemochromatosis are found in homozygotes for the most common mutation in the HFE gene. [1] But at each gene locus associated with the disease, there is the possibility of compound heterozygosity, often caused by inheritance of two unrelated alleles, of which one is a common or classic mutation, while the other is a ...
