Women typically present later in life when they are postmenopausal, likely because of menstrual blood loss delaying the development of symptomatic iron overload.1,3, Genetic testing for the C282Y and H63D mutations of the HFE gene is recommended for first-degree relatives of people with hereditary hemochromatosis; screening does not need to begin until 18 years of age because clinical manifestations are rare before this age.1,3, Population-level genetic testing or laboratory screening for hereditary hemochromatosis is not recommended because of the cost and the variable prevalence and incomplete penetrance of the C282Y mutation.1,35,9, The presentation of hereditary hemochromatosis varies, with biochemical expression occurring first and clinical expression occurring in later stages of disease.3,8 Table 2 summarizes the stages of hereditary hemochromatosis.1,2,4,5, The differential diagnosis includes other causes of secondary iron overload via excess absorption and organ deposition of iron (Table 3).15,10, Hereditary hemochromatosis should be considered in the differential diagnosis of patients with elevated liver enzymes and abnormal iron study results.24,11.

This process involves (1) synthesis of high-affinity ferric ion chelators by bacteria, (2) iron acquisition through LF or transferrin binding, mediated by bacterial-specific surface bacterial receptors, (3) or iron acquisition through bacterial reductases, which are able to reduce ferric to ferrous ions (19, 144148).
