Hereditary hemochromatosis is the most common inherited single-gene disorder in people of northern European descent. It is characterized by increased intestinal absorption of iron, with deposition Haemochromatosis is an inherited condition where iron levels in the body slowly build up over many years. This build-up of iron, known as iron overload, can cause unpleasant symptoms. The C282Y missense mutation of the gene leading to phenotypic hemochromatosis was first described in 1996. 7 H63D has also been identified as a point mutation that predisposes to iron overload to a lesser degree. 7 Among whites, about 90% of patients with hemochromatosis are homozygous for C282Y; 5% to 10% are compound heterozygotes, identified as C282Y/H63D; and 1% to 3% are heterozygous for Blood ferritin levels usually are low in patients with iron deficiency anemia, and are high in patients with hemochromatosis and other conditions that cause an increase in body iron levels.

Hereditary hemochromatosis (HH) is an autosomal recessive disorder characterized by excessive intestinal absorption of dietary iron, causing iron overload in different organs, especially the liver. Hemochromatosis may not be recognized until later in life.

Hemochromatosis is a hereditary disease characterized by improper processing by the body of dietary iron which causes iron to accumulate in a number of body tissues, eventually causing organ dysfunction. It is the main iron overload disorder. Hemochromatosis is notorious for having symptoms that are often initially misattributed to other diseases. The defect in hemochromatosis is that you do not stop absorbing from food when you have enough, and you do not put the iron into ferritin when you have too much.
