Abstract

In northern Europe, about 90% of patients with hereditary haemochromatosis (HH) are homozygous for a single mutation (C282Y) of the HFE gene and approximately 1 in 150 people in the general population carries this genotype. However, the clinical significance of HFE mutations remains uncertain, as is the proportion of people homozygous for C282Y who will develop clinical symptoms leading to a diagnosis of HH. A systematic review of patients with HH over a 2-year period within a defined UK region has revealed that only 1.2% of adult C282Y homozygotes have been diagnosed with iron overload and received treatment. In those in whom body iron load could be estimated, only 51% has more than 4 g iron (the diagnostic threshold for iron overload).
