A European allele map of the C282Y mutation of hemochromatosis: Celtic versus Viking origin of the mutation?

The aim of this new meta-analysis (to the end of 2002) is to compile the Y allele frequencies of the C282Y mutation of hereditary hemochromatosis (HFE gene) for 63 European populations, representing a total of 10,708 unrelated people concerning control samples. A new allele map of C282Y frequencies in Europe was constructed. The highest European frequencies are observed in the Celtic populations in Ireland, in the United Kingdom, and in France, but elevated frequencies are also observed in Scandinavia.
