Genotyping of two mutations in the HFE gene using single-base extension and high-performance liquid chromatography.
Currently, a major focus of human genetics is the utilization of single-nucleotide polymorphisms for clinical diagnostics, whole-genome linkage disequilibrium screens to identify common disease genes such as Alzheimer disease, determination of the recent evolutionary history of a species, and the process of speciation. We have examined single-nucleotide extension coupled with high-performance liquid chromatography as a method to simultaneously genotype two SNPs occurring in the coding region of the HFE gene that produce clinical effects. This assay allows concurrent genotyping of the C282Y and H63D mutations in 11 min and is 100% concordant with current testing methods for both of these mutations.
