HFE gene (hemochromatosis) is a gene located on short arm of chromosome 6 at location 6p21.3.

The protein encoded by this gene is a membrane protein that is similar to MHC class I-type proteins and associates with beta2-microglobulin (beta2M). It is thought that this protein functions to regulate iron absorption by regulating the interaction of the transferrin receptor with transferrin. The iron storage disorder, hereditary haemochromatosis, is a recessive genetic disorder that results from defects in this gene. At least eleven alternatively spliced variants have been described for this gene. Additional variants have been found but their full-length nature has not been determined.^[1]

The gene has two mutant alleles at different loci, H63D and C282Y, which follow an autosomal recessive inheritance pattern and influence iron levels.
