In the case of hemochromatosis, it is believed that a single individual in Europe, 60 to 70 generations ago, was the sole origin of most of the hemochromatosis seen in the world today.
Type I hemochromatosis is caused by defects (mutations) in the HFE gene. HFE has many purposes, but one important role is that it helps to control the amount of iron that is absorbed from food. There are several known mutations in the HFE gene, but presently testing for only three is available: C282Y, H63D, and S65C.
