Heterozygous means the individual carries one copy of a mutation on one chromosome. Additional Hereditary Hemochromatosis DNA Mutation Analysis.
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? Individuals who are heterozygous for C282Y may have mild symptoms of hemochromatosis such as lethargy, joint pain, and weakness but are unlikely to develop the disease. H63D Heterozygote Individuals who are heterozygous for H63D are unlikely to have symptoms of iron overload and are not at significantly increased risk of developing the disease. The risk of hemochromatosis-related morbidity is unknown among HFE compound heterozygotes (C282Y/H63D).

För översiktsartiklar Iron-overload-related disease in HFE hereditary hemochromatosis. N Engl J Med. We found that individuals of the Västerbotten CDA III family carry mutations in the hemochromatosis (HFE) gene.
This subgroup is not well studied, and the natural history of their disease is poorly understood. 12 Approximately 25% of heterozygotes have abnormal iron studies. 1 A smaller percentage have iron overload as high as that of homozygotes.
In 1999 hemochromatosis patients saw an average of 3 doctors and spent 9 years trying to get a complete diagnosis. In 2010 those numbers improved but not enough to catch these three women and countless unknown others.
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. Your body needs iron to stay healthy, make red blood cells, build muscle and heart cells, and do the daily tasks that your body and internal organs need to do. However, too much iron is harmful.

The risk of hemochromatosis-related morbidity is unknown among HFE compound heterozygotes (C282Y/H63D). We used a prospective population-based cohort study to estimate the prevalence of elevated iron indices and hemochromatosis-related morbidity for compound heterozygotes.
fastställs med gentest. Det finns i huvudsak två mutationer av sjukdomsgenerna, 10% av populationen har heterozygot och 0,5% homozygot uppsättning. Denna mutation förekommer hos ca 1/15 av den svenska befolkningen i heterozygot form och hos ca 1/200 i homozygot form .

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.
Among 29 699 white subjects participating in the Scripps/Kaiser hemochromatosis study, only 59 had serum ferritin levels more than 1000 μg/L; 24 had homozygous mutant or compound heterozygous mutant HFE genotypes. In all but 5 of the other subjects, the causes of elevated ferritin were excessive alcohol intake, cancer, or liver disease. Heterozygous for p.C282Y. Heterozyous for p.C282Y (also known as carriers) Implications for the patient.
