Homozygosity for the mutation Cys282Tyr in the HFE gene has recently been identified as a cause of hereditary hemochromatosis, a disorder resulting in the inappropriate absorption of iron. Approximately 10% of Caucasians are heterozygous for this mutation; however, the gene frequency in African Amer
?-thalassemia trait might increase the severity of hemochromatosis in subjects with the C282Y mutation in the HFE gene

✦ Synopsis
With the C282Y Mutation in the HFE Gene
To the Editor: The association between hereditary hemochromatosis and thalassemia syndrome might lead to a severe iron overload [1,2], but the results are still controversial. By PCR and restriction enzyme digestion [3], we analyzed the C282Y and H63D mutations in the HFE gene in one family whose propositus carried the -thalassemia trait. The patient was a female, 38 years old, presenting weakness and arthralgia. She had 4 children and received transfusion (1 unit of red cell) during her last gestation. She did not present diabetes or cardiac disease and her hepatic enzymes were normal. Her mother and 2 sons also carried the -thalassemia trait.
