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. If it is not treated, this can damage parts of the body such as the liver, joints, pancreas and heart.
Individuals who are heterozygous for S65C and either the wild-type or H63D alleles do not seem to be at an increased risk for HH. The S65C mutation is only reported when it is part of the C282Y/S65C genotype. See Hereditary Hemochromatosis Algorithm in Special Instructions.
If the mutation is associated with a Homozygous means the individual carries two copies of the same mutation, one on each chromosome. Type I hemochromatosis is caused by defects (mutations) in the HFE gene. HFE has many purposes, but one important role is that it helps to control the amount of iron that is absorbed from food. There are several known mutations in the HFE gene, but presently testing for … Heterozygous C282Y mutation Heterozygotes of the C282Y mutation represent a small proportion of patients with hemochromatosis.
Too much iron can lead to life-threatening conditions, such as liver disease, heart problems and diabetes. Heterozygous means the individual carries one copy of a mutation on one chromosome. If the mutation is associated with a recessive disease such as hereditary hemochromatosis (HH), the individual is called a carrier. Carriers are typically unaffected, that is, they show no symptoms of the disease. Heterozygosity for the C282Y mutation in the hemochromatosis gene is associated with increased serum iron, transferrin saturation, and hemoglobin in young women: a protective role against iron deficiency?
When should 1 Mar 2002 Iron overload also occurs in a minority of persons with other HFE mutations ( especially compound heterozygotes, who have one copy of C282Y 1 Feb 2013 Hereditary hemochromatosis is an autosomal recessive disorder that disrupts the body's regulation of iron.
What do “heterozygous,” “homozygous,” or “compound heterozygous” results mean? Heterozygous means the individual carries one copy of a mutation on one chromosome. If the mutation is associated with a Homozygous means the individual carries two copies of the same mutation, one on each chromosome.

Heterozygous: Having one copy of the abnormal HFE gene, for example C282Y or H63D – also known as a ‘carrier’. Homozygous: Two copies of the same gene abnormality, for example C282Y and C282Y. Compound heterozygous: Having one C282Y and one H63D abnormal gene. Compound heterozygotes usually have a milder form of haemochromatosis.
Hemochromatosis: Introduction Hemochromatosis was first identified in the 1800s, and by 1935 it was understood to be an inherited disease resulting in iron overload and deposition. Today, hemochromatosis is defined as a metabolic disorder affecting iron absorption , and resulting in the accumulation of excess iron in the body’s organs. Haemochromatosis is an autosomal-recessive disorder.

Iron overload may arise in compound heterozygotes for the C282Y and the H63D gene variants. This genotype is present in 5% of clinically affected people. 1 in 70 (1.3%) people in the European population have this genotype. Hemochromatosis is a disorder in which extra iron builds up in the body to harmful levels.
