TEST DETAILS
Reference interval:
Negative.
Interpretation guide:
Hereditary hemochromatosis (HH) is an autosomal recessive disorder of iron metabolism that results in iron overload and potential organ failure. It is one of the most common genetic disorders in individuals of European-Caucasian ancestry with an estimated carrier frequency of 10%. The most common forms of HH are due to HFE gene mutation with homozygous for C282Y (60-90%) genotype. The C282Y heterozygote, H63D heterozygote and homozygote and H63D/S65C compound heterozygote genotypes may be associated with iron overload and increased transferrin saturation (TS) relative to the wild type in the general population. This assay detects the two most common mutations in the HFE gene, C282Y (NM_000410.4:c.845G>A) and H63D (NM_000410.4:c.187C>G). HFE S65C (NM_000410.4:c.193A>T), although less clinically significant in HH, is also covered in this test. The mutations are detected by multiplex polymerase chain reaction (PCR) amplification (Thermo Fisher). This assay does not detect other mutations in the HFE gene that may cause HH. Since genetic variation and other factors can affect the accuracy of direct mutation testing, these results should be interpreted in light of clinical and familial data.

Clinical significance:
Hereditary Hemochromatosis (HH) is an inherited disorder resulting in excess iron accumulate in the body. This test confirms HH diagnosis in patients with abnormal iron studies, and identifies at-risk individuals.
