| Abstract: |
Over 90% of patients with hemochromatosis in the United Kingdom are homozygous for the C282Y mutation on the HFE gene. The Centers for Disease Control (CDC) in the United States has recommended that adults should be screened for HFE mutations to identify susceptible individuals before onset of disease. The aim of this study was to evaluate the polymerase chain reaction using sequence-specific primers (PCR-SSP) as a method of large-scale population screening for the common HFE gene mutations, H63D and C282Y. A total of 10,583 consenting blood donors were tested using nonautomated procedures. Three alleles, termed HFE -1, -2, and -3, were detected with phenotype frequencies of 94.56%, 28.33%, and 15.79%, respectively, and gene frequencies of 0.76421, 0.15342, and 0.08237, respectively. All donors identified as homozygous for the C282Y mutation or heterozygous for both the H63D and C282Y mutations were confirmed by heterduplex analysis and/or PCR-SSP. The number of technical failures that affected the identification of donors homozygous for the C282Y mutation was 390 giving an overall repeat rate 3.7%, although this fell to 1% over the last quarter of the study. This study demonstrates that PCR-SSP may be used for large-scale population screening for the C282Y genotype associated with hemochromatosis. |
