The new approach is used for identification of C282Y (C), H63D (H), and S65C (S) mutations in the HFE gene. In a group of 40 samples we amplified specific parts of HFE exon 2 and exon 4 by multiplex PCR.
Purified amplicons were subsequently used in a multiplex cycle sequencing reaction containing a hyperadenylated reverse primer for exon 2. Adenylation prolonged the migration time of the exon 2 amplicons in the electrophoretic capillary.
This enabled us to obtain separated sequencing data for both the studied amplicons. We found six subjects with the risk of hereditary hemochromatosis (15 %).
