Hereditary hemochromatosis is a rare genetic disorder that causes the body to absorb and store too much iron from food. Iron is essential for various bodily functions, such as making red blood cells and carrying oxygen throughout the body. However, in individuals with hereditary hemochromatosis, excessive iron buildup can lead to serious health problems.
There are several types of hereditary hemochromatosis, with the most common type being caused by mutations in a gene called HFE. Other genes, such as HAMP, TFR2, and SLC40A1, have also been associated with different forms of the condition. The inheritance pattern of hereditary hemochromatosis is typically autosomal recessive, meaning that both parents must carry a mutated gene for their child to be affected. However, in some rare cases, an autosomal dominant inheritance pattern may occur.
The symptoms of hereditary hemochromatosis can be nonspecific and vary greatly from person to person. Some individuals may experience fatigue, joint pain, abdominal pain, or an enlarged liver. Over time, excessive iron accumulation can lead to more serious complications, such as liver disease, heart problems, and hormonal imbalances.
Research and clinical trials are ongoing to better understand the underlying causes of hereditary hemochromatosis and develop more effective treatments. Various resources, such as the National Center for Advancing Translational Sciences (NCATS) and the Genetics Home Reference, provide additional information about the genes associated with this condition, as well as clinical trials and support resources for patients and their families.
In conclusion, hereditary hemochromatosis is a rare genetic disorder characterized by excessive iron absorption and storage in the body. It is associated with mutations in various genes, and its inheritance pattern can vary. Early detection and appropriate management, including regular monitoring and therapeutic phlebotomy, can help prevent complications and improve outcomes for individuals with hereditary hemochromatosis.
Frequency
Hereditary hemochromatosis is a fairly common genetic disorder, particularly in people of Northern European descent. It is estimated to affect approximately 1 in every 200 to 300 individuals in the United States. The frequency of hereditary hemochromatosis varies depending on the population being studied.
Given the high cost of medical care, it’s hardly a shock that patients are drowning in medical debt. Almost 20% of American households have delinquent medical bills that affect their credit report, according to NBC News. Having medical bills in collections makes it more difficult for patients to engage in other economic activities, such as purchasing a home or securing a loan to start a business.
According to the Center for Disease Control and Prevention (CDC) and the National Center for Biotechnology Information (NCBI), hereditary hemochromatosis is the most common genetic disorder in the Caucasian population. It is less commonly found in individuals of Asian, African, and Hispanic descent.
There are several different genes that can cause hereditary hemochromatosis, the most common being the HFE gene. Mutations in the HFE gene are responsible for approximately 80 to 90% of cases of hereditary hemochromatosis.
ClinicalTrials.gov is a valuable resource to learn more about ongoing research and clinical trials related to hereditary hemochromatosis. Other names for this condition include: Hemochromatosis, Hereditary Type; Juvenile Hemochromatosis; Hemochromatosis, Type 1; and Hemochromatosis, Type 2A.
It is important for patients with hereditary hemochromatosis to receive regular medical check-ups and monitoring. Testing for hereditary hemochromatosis is typically done through blood tests to check iron levels and genetic testing to identify any mutations in the associated genes. The Liver Diseases and Genetic Testing section of the ClinicalTrials.gov website and the OMIM (Online Mendelian Inheritance in Man) catalog provide additional information about genetic testing and related disorders.
In individuals with hereditary hemochromatosis, iron builds up in the body over time. This excess iron can lead to various complications and health problems, particularly affecting the liver. It is important for patients to follow a controlled diet and receive treatment to manage the condition.
Support groups and resources are available to help patients and their families cope with hereditary hemochromatosis. The Rare Diseases section of the National Institutes of Health (NIH) website provides scientific articles and information about hereditary hemochromatosis. Information about clinical trials and ongoing research studies can be found on websites such as PubMed and ClinicalTrials.gov.
Gasparini et al. conducted a study on the frequency of different types of hereditary hemochromatosis and associated genes. The study found that the HFE gene mutation was the most common cause of hereditary hemochromatosis, followed by mutations in other genes such as TFR2, HAMP, and HJV. The study also highlighted the importance of understanding the different types and causes of hereditary hemochromatosis for accurate diagnosis and appropriate management of the condition.

Causes
Hereditary hemochromatosis (HH) is often caused by mutations in the genes that regulate the absorption and metabolism of iron in the body. Mutations in the HFE gene are the most common cause of HH, accounting for about 85-90% of cases. Other rare genes associated with hereditary hemochromatosis include HJV, HAMP, and TFR2.
Inheritance of hereditary hemochromatosis is autosomal recessive, meaning that an individual must have two copies of the mutated gene to develop the condition. If an individual inherits only one mutated gene, they are considered a carrier and do not typically experience symptoms of iron overload.
The precise mechanisms by which mutations in these genes lead to iron overload are not fully understood. However, it is believed that these mutations result in increased absorption of iron from the diet and impaired regulation of iron levels in the body, leading to excessive accumulation of iron in various tissues, particularly the liver.
Additionally, other factors such as age, gender, and hormones may play a role in the development and progression of hereditary hemochromatosis. Men are more commonly affected by the condition than women, and symptoms usually appear after the age of 40 in men and after menopause in women.
Some rare types of hereditary hemochromatosis may be associated with other diseases and disorders. For example, juvenile hemochromatosis typically begins in adolescence or early adulthood and is associated with heart disease and endocrine abnormalities.
Genetic testing is available to confirm a diagnosis of hereditary hemochromatosis and to identify the specific genes involved. Additional testing may be done to assess the severity of iron overload and to monitor the response to treatment.

It is important for patients with hereditary hemochromatosis to undergo genetic testing to confirm a diagnosis and determine the specific gene mutations involved. Genetic testing can also be used to identify carriers of the mutated genes, allowing for early detection and intervention in at-risk individuals.
For patients who are diagnosed with hereditary hemochromatosis, there are several treatment options available. These may include regular blood donations to reduce excess iron levels, iron chelation therapy to remove excess iron from the body, and dietary changes to limit iron intake.
In addition to genetic causes, there are also other causes of iron overload that can result in a similar clinical presentation to hereditary hemochromatosis. These include certain types of anemia, chronic liver disease, and excessive iron supplementation.
Further information and support for patients with hereditary hemochromatosis can be found through advocacy organizations such as the Hereditary Hemochromatosis organization and the Iron Disorders Institute. These organizations provide resources, support, and information on clinical trials and research studies related to the condition.
