A patient with abnormally high iron levels is tested to determine if hemochromatosis, specifically the C282Y mutation in the HFE gene, is the cause. The patient’s DNA is isolated from whole blood and amplified. Amplicons are then cut with RsaI, and the resulting fragments are separated by gel electrophoresis. There are no RsaI sites in the normal 250 bp PCR product, while the C282Y mutation generates one RsaI site. The lane containing the patient’s sample has three bands at 250 bp, 140 bp, and 110 bp. Controls were acceptable. Which of the following is the correct interpretation of these results?
