[Frequency of HFE gene mutations and genotype-phenotype correlations in patients with hereditary hemochromatosis in Switzerland].
Hereditary haemochromatosis is one of the most common genetic disorders affecting populations of European ancestry. Isolation of a strong candidate gene, the HFE gene, allows genetic diagnosis in a large number of cases. However, different mutation frequencies have been reported in hereditary haemochromatosis patient populations from various geographic regions. ⋯ However, the diagnosis is not ruled out by a negative genetic test. Furthermore, a broad phenotypic spectrum is associated with the homozygous C282Y mutation in Swiss hereditary haemochromatosis patients. The implications of these findings for planning of widespread genetic screening for hereditary haemochromatosis in the general population are discussed.
