Complete Scanning of the Hereditary Hemochromatosis Gene (HFE) by Use of

erozygotes or lack both of these two common HFE mutations, and 15 novel HFE mutations have been described recently. We evaluated denaturing HPLC (DHPLC) for screening of the whole HFE coding region and further defined whether HC probands with an incomplete HFE genotype carry uncommon mutations. Methods: Analytical conditions for each coding exon were determined by a combination of computer melting profile predictions and experimental melting curves. To test accuracy for scanning the complete HFE coding region and optimize DHPLC running conditions, each melting domain was investigated with at least one mutation or one polymorphism as reference. We tested 100 DNA samples harboring the C282Y, H63D, or S65C mutations and 17 artificially created positive control
