DNA Hemochromatosis Test

Find out if you are at risk of hereditary hemochromatosis with this DNA test.

  • Detects common mutations in the HFE gene
  • About 1 in 200 individuals of European ancestry carry two mutated copies and are at risk of developing hemochromatosis



Hemochromatosis is a hereditary disease that is caused by increased absorption and storage of iron from food. Excess iron is stored in organs like the liver, heart and pancreas that will eventually lead to organ damage causing irreversible diseases such as arthritis, liver disease, heart disease and diabetes later in life.

When identified, hemochromatosis can be managed. As such screening is recommended so the disease can be detected and treated early. If one family member tests positive for hemochromatosis it is recommended that other family members also get tested for the condition.

The HFE gene

Three genetic variants in the HFE gene accounts for 85% of all cases of hereditary hemochromatosis. This DNA test detects the following three mutations:

  • C282Y – Most common variant and is associated with most severe symptoms
  • H63D – Second most common mutation of HFE. Individuals who inherit two copies of this mutation are at increased risk of hemochromatosis
  • S65C – Rare mutation. When inherited together with the C282Y mutation increases the risk of hemochromatosis

How common is hemochromatosis?

Hemochromatosis is the most common genetic disorder for individuals of European descent. About 1 in 9 individuals of European ancestry carry at least one defective copy of HFE. Approximately 1 in 200 individuals of European ancestry carry 2 copies of HFE and develop hemochromatosis. People with Northern European decent such as British, Scottish, Irish, Dutch, Danish, Scandinavian, German, French, Spanish and Italian are most at risk for developing hemochromatosis.

While both men and women can inherit the defective gene, men are more likely to be diagnosed. On average men develop symptoms between the ages of 30-50 compared to women who are diagnosed after 50, often 10-15 years after menopause.

Early symptoms of hemochromatosis

Hemochromatosis is hard to diagnose because it involves symptoms seen in many other conditions. Symptoms also vary between individuals and manifests only later in life.

Early symptoms of Hemochromatosis include:

  • Joint pain – in hands, hips, knees and/or ankles (one of the earliest symptoms)
  • Chronic fatigue (also one of the earliest symptoms)
  • Lack of energy
  • Weakness
  • Abdominal pain
  • Loss of sex drive, impotence
  • Heart problems (heart flutters, irregular heart beat)
  • General darkening of skin color (bronzing)
  • Lack of normal menstruation, premature menopause
  • High blood sugar levels
  • Low thyroid function
  • Abnormal liver function test
  • Depression
  • Shortness of breath
