Clinical Significance
Hereditary Hemochromatosis is an autosomal recessive disease that results in an abnormal build-up of iron in the body. The C282Y and H63D are among the most common mutations in patients with hereditary hemochromatosis. Penetrance of the mutations (phenotypic disease), including by individuals with compound heterozygous mutations, is variable.
