Novel method for molecular detection of the two common hereditary hemochromatosis mutations.

We describe a novel molecular screening technique for hereditary hemochromatosis through which HFE genotypes at codon positions 282 and 63 are simultaneously detected. The technique combines multiplex PCR and denaturing high-performance liquid chromatography (DHPLC) and allows automated high-throughput analysis. We used this method to genotype 43 previously characterized anonymous DNA specimens in blinded fashion and found multiplex PCR/DHPLC 100% accurate when compared with PCR/restriction enzyme digestion, yet far more efficient.
