Overview
Causes
The amount of iron the human body absorbs is controlled by many genes. Genes can sometimes change (or mutate) in ways that keep them from working properly.
Hereditary hemochromatosis can occur when a person inherits two mutated copies of a gene called the HFE gene — one from each parent. Men and women have the same chance of inheriting two copies of this gene.
Not everyone who is born with two copies of the mutated HFE gene develops the disease. Scientists do not know what percentage of people who have two copies of the mutated HFE gene develop the disease. Some studies have shown that as few as 1 in 100 people will develop symptoms. Other studies have shown that as many as 50 in 100 people may develop symptoms.
A person with only one copy of the mutated HFE gene is usually healthy and is said to be a “carrier” of the genetic condition. Although a carrier usually does not have hemochromatosis, if both a mother and father are carriers, a child may inherit two copies of the mutated gene, one from each parent.
