The presence of a single H63D mutation is an extremely common polymorphism, occurring in approximately 25% of a healthy population. Individuals with a heterozygous H63D genotype almost never develop HH. Approximately 2% of Caucasians have a homozygous H63D genotype. These individuals appear to have a mildly increased risk of developing HH.

Yes. The assay tests for both the C282Y and the H63D mutations. So, if the result indicates that your patient is heterozygous for the H63D mutation, then he/she is negative for the C282Y mutation.

HFE C282Y/H63D compound heterozygotes are at low risk of hemochromatosis-related morbidity. For male compound heterozygotes, mean iron indices do not change during middle age but for female compound heterozygotes menopause results in increased mean SF. The HFE H63D is a single-nucleotide polymorphism in the HFE gene (c.187C>G, rs1799945), which results in the substitution of an aspartic acid for a histidine at amino acid position 63 of the HPE protein (p.His63Asp). HFE participates in the regulation of iron absorption. Homozygous H63D variant can occasionally be the cause of hemochromatosis. 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.

C282Y heterozygotes are reflexed to H63D for an additional charge. C282Y heterozygous; H63D homozygous; H63D heterozygous; C282Y/H63D compound heterozygous . Reference value is normal, meaning that the hemochromatosis gene was not detected. Specimen requirement is one 5 mL lavender top (EDTA) tube of blood.

Hereditary hemochromatosis (HH) is an autosomal recessive disease characterized by iron accumulation in several organs, followed by organ damage and failure. The C282Y mutation in the HFE gene explains 80-90% of all diagnosed cases of HH in populations of northwestern European ancestry.

The final scenario is heterozygous for either C282Y or H63D. This means you have only one copy of only one of the genes. This is often (but not always) the least severe manifestation of the condition. In summary: Homozygous–> 2 copies of C282Y. Most likely to be severe. Compound Heterozygous –> 1 copy of C282Y + 1 copy of H63D. Second most Hereditary hemochromatosis (HH) is an autosomal recessive disorder of iron metabolism characterized by increased iron absorption and tissue deposition.

The HFE gene has two common mutations, C282Y and H63D. Genetic testing can reveal whether you have these mutations in your HFE gene.

The risk of HH related morbidity in HFE compound homozygotes patients (H63D /H63D) is considered rare, we report a male patient with H63D mutation who developed impaired glucose tolerance, and high hepatic enzymes due to significant iron accumulation in the liver as well as Parkinsonian-like syndrome due to iron deposition in the basal ganglia. HFE C282Y/H63D compound heterozygotes are at low risk of hemochromatosis-related morbidity. For male compound heterozygotes, mean iron indices do not change during middle age but for female compound heterozygotes menopause results in increased mean SF. The HFE H63D is a single-nucleotide polymorphism in the HFE gene (c.187C>G, rs1799945), which results in the substitution of an aspartic acid for a histidine at amino acid position 63 of the HPE protein (p.His63Asp).

1 May 2017 A recent study demonstrated that 80% of successful French athletes carry a heterozygous HFE mutation (C282Y, H63D or S65C) suggesting 

Few studies have focused the pathological value of C282Y/H63D. Hereditary hemochromatosis (HH) is an autosomal recessive disease characterized by iron accumulation in several organs, followed by organ damage and failure. The C282Y mutation in the HFE gene explains 80-90% of all diagnosed cases of HH in populations of northwestern European ancestry. Targeted disruption of the mouse Hfe gene (or introduction of the murine mutation analogous to the C282Y The HFE mutation that most commonly causes hemochromatosis is called C282Y. Another HFE mutation that may lead to iron overload is called H63D. People with two copies of C282Y are most likely to have iron overload. People with one copy of H63D and one copy of C282Y may also have iron overload, but this is less common and usually less severe.

2009-09-04 · Compound Heterozygous Hemochromatosis: Long-Term Outcomes Atif Zaman, MD, MPH , reviewing Gurrin LC et al. Hepatology 2009 Jul People with C282Y/H63D mutations in the HFE gene were no more likely than people with neither mutation to develop hemochromatosis-related morbidity.

This genotype is present in 5% of clinically affected people. 1 in 70 (1.3%) people in the European population have this genotype. This genotype appears to be associated with a small increased chance of developing (usually mild) iron overload. This makes them compound heterozygous for haemochromatosis and puts them greatly at risk of storing excess iron in the body. [ medical citation needed ] Homozygosity for the C282Y genetic variant is the most common genotype responsible for clinical iron accumulation, though heterozygosity for C282Y/H63D variants, so-called compound heterozygotes , results in clinically evident iron overload. There are several known mutations in the HFE gene, but presently testing for only three is available: C282Y, H63D, and S65C. Everyone inherits two copies of HFE, one from Mom and one from Dad. When a person has one mutated copy, he or she is called a carrier or heterozygote.

I hope you share your experiences and if you have any information that you would like to share with others then please post it here. This group is not run/administrated by anyone with a medical background. 2019-01-01 The most common HH genotype is homozygosity for the C282Y variant (C282Y/C282Y) and is mainly responsible for clinical hemochromatosis in Caucasians.
