Hemochromatosis (HFE) 2 Variants Analysis by Real-Time PCR
CPT Code(s)
81256, G0452
Synonym(s)
HFE Gene Analysis; Hereditary Hemochromatosis (C282Y and H63D mutation), Hereditary Hemochromatosis DNA Mutation Analysis
Performed
Molecular Diagnostics Laboratory
Clinical Indication and Relevance
The assay is useful for patients with iron overload, and/or a family history of hereditary hemochromatosis.
Methodology
DNA is isolated from the patient sample and regions of the HFE gene are amplified by real-time PCR and the p.H63D and p.C282Y variants are detected by the allelic discrimination method. Results are reported as normal, heterozygous or homozygous for the p.H63D and/or p.C282Y variants.
