About Hemochromatosis

Hemochromatosis is a hereditary condition characterized by excessive absorption of dietary iron, leading to accumulation in various organs and potential damage over time. Common symptoms include fatigue, joint pain, and abdominal pain. If left untreated, it can lead to serious complications such as liver disease, heart problems, and diabetes.

The onset of symptoms may go unnoticed for years. Men typically start experiencing symptoms between ages 30 and 50, whereas women tend to develop symptoms after age 50, often well into post-menopause. Early detection plays a crucial role in managing hereditary hemochromatosis effectively.

The Genetics

The DNA Hemochromatosis Test identifies three specific genetic variations within the HFE gene linked to an increased likelihood of developing hemochromatosis:

• C282Y Mutation: The most common mutation associated with hemochromatosis, often linked to the most severe symptoms.
• H63D and S65C Mutations: These additional mutations can also increase risk, though their effects are generally less severe than C282Y.

How Is Hemochromatosis Inherited?

Hemochromatosis is an autosomal recessive disorder, meaning a person must inherit two mutated versions of the HFE gene to develop symptoms. The highest risk is seen in individuals with two copies of the C282Y mutation, which occurs in about 80 to 85% of diagnosed cases. Compound heterozygosity (e.g., one C282Y and one H63D) can lead to a milder form of the condition.

Understanding Your Risk

Hereditary hemochromatosis affects many individuals, particularly those of European descent. Approximately 1 in every 300 people with European ancestry carries two copies of the C282Y mutation. While inheriting two mutated HFE genes raises risk, not everyone with these genetic markers will develop symptoms, as environmental and lifestyle factors such as alcohol use or existing liver conditions can also play a role.

Early Symptoms of Hemochromatosis

• Persistent fatigue and general weakness
• Joint pain, particularly in the hands
• Memory difficulties
• Depression
• Shortness of breath
• Irregular heart rhythms
• Elevated blood sugar levels
• Reduced thyroid function

Early diagnosis and treatment are critical to prevent complications. Individuals with a family history of the disorder are strongly encouraged to discuss genetic testing with their healthcare provider.

Frequently Asked Questions

Does a positive result mean I have hemochromatosis?
Not necessarily. Carrying HFE gene mutations increases your genetic risk but does not confirm a diagnosis. Many carriers never develop symptoms. A positive result should be discussed with your physician, who may recommend follow-up blood tests such as serum ferritin or transferrin saturation levels.

Who should consider this test?
This test is particularly recommended for individuals with a family history of hemochromatosis, those of Northern European descent, or anyone experiencing unexplained fatigue, joint pain, or elevated liver enzymes. Early detection allows for proactive management before organ damage occurs.

How is the DNA sample collected?
DNA is collected using a painless buccal (cheek) swab. Simply rub the swab gently inside your mouth against your cheek for 15 seconds. No needles, blood draws, or clinic visits are required.

How long does it take to receive results?
Results are delivered securely online within 1 to 3 business days after the laboratory receives your sample. You will be notified by email when your results are available.
