A study of genes that may modulate the expression of hereditary hemochromatosis: transferrin receptor-1, ferroportin, ceruloplasmin, ferritin light and heavy chains, iron regulatory proteins (IRP)-1 and -2, and hepcidin.
We have examined transferrin receptor-1, ferroportin, ceruloplasmin, ferritin light and heavy chains, iron regulatory proteins (IRP)-1 and -2, and hepcidin for mutations that might modulate the iron burden of individuals harboring the common mutant hemochromatosis HFE genotype C282Y/C282Y or cause hemochromatosis independent of mutations in the HFE gene. In a group of white, Asian, and African-American normal and iron-overloaded individuals, the coding and flanking regions of these genes were completely sequenced. Numerous coding region and promoter polymorphisms were detected. These were further examined for association with differences in iron accumulation as measured by plasma transferrin saturation and ferritin levels, but no such association could be documented.
