HFE Gene Mutations

What is the HFE gene mutations test?

The HFE gene mutations test detects genetic changes in the HFE gene, which regulates iron absorption. Mutations in this gene, particularly C282Y and H63D, can lead to hereditary hemochromatosis (HH), a condition causing excessive iron accumulation in the body.


Who should get this test?

Testing is recommended for individuals with:

A family history of hereditary hemochromatosis
Unexplained high iron levels or ferritin
Symptoms such as fatigue, joint pain, or liver dysfunction



How is the test performed?

A blood sample is collected and analyzed using polymerase chain reaction (PCR) or DNA sequencing to identify HFE gene mutations.


What do the results mean?


C282Y homozygous: High risk of developing HH.
C282Y/H63D compound heterozygous: Moderate risk of iron overload.

H63D homozygous or heterozygous: Low risk, but monitoring may be necessary.


Can this test help in treatment decisions?

Yes, a positive result guides early intervention through phlebotomy or chelation therapy to prevent organ damage caused by iron overload.
