Mutation analysis in the HFE gene in patients with hereditary haemochromatosis in Saguenay–Lac-Saint-Jean (Quebec, Canada)
2000
A mutation analysis of the HFE gene followed, when applicable, by sequencing was performed on 47 patients with hereditary haemochromatosis (HH) living in Saguenay–Lac-Saint-Jean. The C282Y and H63D mutations were present on 50% and 20·3% of the HH chromosomes respectively. These frequencies were very different from those found in other populations and could be, at least partially, the result of a founder effect. No new mutation was identified among the remaining 28·1% of the HH chromosomes. Five of the eight probands with no mutation in the HFE gene had a severe and early onset suggestive of juvenile haemochromatosis.
