Hemochromatosis DNA Test

Hemochromatosis is an autosomal recessive genetic disorder, meaning both parents must pass on a mutated version of the HFE gene for the condition to develop. The highest risk of symptoms arises in individuals with two copies of the C282Y mutation, which accounts for 80-85% of diagnosed cases. Other mutations, like H63D or S65C, carry a lower risk of symptoms, though they can still lead to iron overload under certain conditions.

Compound heterozygosity, where a person inherits different mutations (e.g., C282Y and H63D), may result in a milder form of the disease. In contrast, combinations such as H63D and S65C do not significantly affect the risk.

While individuals with two copies of the C282Y mutation have a higher risk of developing hemochromatosis, environmental factors, including alcohol consumption and liver disease, can trigger iron overload in susceptible individuals. The condition is more prevalent among people of European descent, with 1 in 300 carrying two C282Y mutations.

Hereditary hemochromatosis is a genetic disorder, most commonly affecting individuals of European descent. Research shows that about 1 in 300 people of European ancestry inherit two copies of the C282Y mutation, significantly increasing the risk of developing the condition. While those with only one mutated gene typically don’t show symptoms, certain lifestyle factors like excessive alcohol consumption or existing liver issues can trigger iron overload in at-risk individuals.
Inheriting two mutated HFE genes increases the likelihood of hemochromatosis, but not everyone with these genetic markers will experience symptoms. Environmental factors, such as liver disease or alcohol use, can contribute to the onset of the disorder in genetically predisposed individuals.

Because the early signs of hemochromatosis are often nonspecific, they can be mistaken for other health issues. Common early symptoms include:

• Fatigue and weakness
• Joint pain (especially in hands)
• Memory issues
• Depression and mood changes
• Shortness of breath and irregular heart rhythms
• Elevated blood sugar and thyroid dysfunction

Early detection is crucial, especially for individuals with a family history. Proactive testing and lifestyle adjustments can help manage symptoms and prevent severe complications.

The main treatment for hemochromatosis is to lower excess iron in the body, usually through:

1. Phlebotomy (Blood Removal)
   • Removing blood regularly (like donating blood) helps reduce iron levels. It’s typically done once or twice a week initially and then less often as iron levels drop.
2. Chelation Therapy
   • For those who can’t have blood removed, medications are used to help remove excess iron through urine or stool.
3. Dietary Changes
   • Avoiding iron-rich foods (like red meat) and limiting vitamin C, which increases iron absorption, is recommended. Reducing alcohol intake is also important, especially for liver health.
4. Regular Check-ups
   • Regular blood tests help monitor iron levels and adjust treatment. Doctors also check for any liver or heart problems caused by excess iron.
5. Managing Complications
   • If iron overload has caused damage, additional treatments may be needed for conditions like liver disease or diabetes.

Early treatment helps prevent serious complications from iron buildup, like liver or heart problems.
