Abstract

Background: Polymorphisms in the hemochromatosis (HFE) gene are associated with excessive iron absorption from the diet, and pro-oxidant effects of iron accumulation are thought to be a risk factor for several types of cancer. Methods: The C282Y (rs1800562) and H63D (rs1799945) polymorphisms were genotyped in 301 oral cancer cases and 437 controls and analyzed in relation to oral cancer risk, and serum iron biomarker levels from a subset of 130 subjects. Results: Individuals with the C282Y allele had lower total iron binding capacity (TIBC) (3212 ± 372 µg/dL vs. 3977 ± µ890 g/dL, p = 0007) and higher percent transferrin saturation (220 ± 87 vs. 356 ± 229, p = 0023) than wild type individuals. Iron and ferritin levels approached significantly higher levels for the C282Y allele (p = 00632 and p = 00588, respectively). Conclusions:Iron biomarker levels were elevated by the C282Y allele, but neither (rs1800562) nor (rs1799945) was associated with oral cancer risk in blacks and whites.
