Hereditary antithrombin deficiency is a rare genetic condition that causes an increased risk of blood clots. It is caused by mutations in the SERPINC1 gene, which codes for the antithrombin protein. Antithrombin is a natural anticoagulant in the bloodstream, and a deficiency in this protein can lead to abnormal clotting.

Hereditary antithrombin deficiency is inherited in an autosomal dominant pattern, which means that a person with one copy of the mutated gene has a 50% chance of passing the condition on to each of their offspring. The condition can cause a variety of symptoms, including deep vein thrombosis, pulmonary embolism, and other clotting disorders.

Diagnosis of hereditary antithrombin deficiency is usually made through genetic testing. Testing can be done at a specialized genetics center or through commercial genetic testing companies. Additional information, including research articles, clinical trials, and patient advocacy resources, can be found on websites such as Pubmed, ClinicalTrials.gov, and the Genetic Testing Catalog.

Management of hereditary antithrombin deficiency usually involves lifelong anticoagulation therapy to prevent clotting episodes. Supportive care and genetic counseling can also be beneficial for individuals and families affected by the condition. More research is needed to develop targeted treatments for this rare genetic condition.

Frequency

The frequency of hereditary antithrombin deficiency is rare. It is estimated to occur in approximately 1 in 2,000 to 5,000 individuals in the general population.

Hereditary antithrombin deficiency is caused by mutations in the SERPINC1 gene. These mutations can block the production or function of antithrombin, a blood protein that helps regulate clotting. Without enough functional antithrombin, individuals with this condition have an increased risk of developing blood clots.

Once you do get to see the doctor, don’t be surprised if you’re rushed out of the exam room before you get all of your questions answered, according to healthcare staffing agency Staff Care. Studies show that 41% of ophthalmologists spend just 9 to 12 minutes with a patient, and 13- to 16-minute appointments are the norm for 40% of cardiologists, 37% of pediatricians, 35% of urologists, 35% of family physicians, 34% of obstetricians and gynecologists and 30% of otolaryngologists.

The inheritance pattern of hereditary antithrombin deficiency is autosomal dominant, which means that a person with one copy of the mutated gene has a 50% chance of passing the condition on to each of their children.

There are several resources available for patients and their families to learn more about hereditary antithrombin deficiency. The Hereditary Antithrombin Deficiency Registry, supported by the Centers for Disease Control and Prevention, provides information and support for individuals with this condition. The registry collects information on the genetics, clinical features, and frequency of hereditary antithrombin deficiency. Additional patient resources can be found on the National Center for Biotechnology Information’s Online Mendelian Inheritance in Man (OMIM) database.

Scientific articles and research studies on hereditary antithrombin deficiency can be found in the PubMed database. The OMIM website also provides a catalog of rare diseases, including hereditary antithrombin deficiency, and references for further reading.

Genetic testing is available to diagnose hereditary antithrombin deficiency and is typically recommended for individuals with a personal or family history of blood clots or other clotting disorders.

ClinicalTrials.gov provides information on current research studies for hereditary antithrombin deficiency and other genetic clotting disorders. Participation in these studies may provide access to new treatments or therapies.

It is important for individuals with hereditary antithrombin deficiency to work closely with their healthcare providers and genetic counselors to manage their condition and reduce the risk of blood clots.

Causes

The main cause of hereditary antithrombin deficiency is a mutation in the SERPINC1 gene, which provides instructions for making the protein antithrombin. Antithrombin plays a crucial role in preventing blood clots by inhibiting certain clotting factors in the bloodstream. Mutations in the SERPINC1 gene can lead to a decreased production or impaired function of antithrombin, resulting in an increased risk of clotting.

Hereditary antithrombin deficiency follows an autosomal dominant inheritance pattern, which means that individuals with a single copy of the mutated gene are affected by the condition. In some cases, the condition can also occur due to a spontaneous genetic mutation.

The frequency of hereditary antithrombin deficiency is relatively rare, with an estimated prevalence of about 1 in 2,000 to 5,000 individuals. It is more common in individuals of European ancestry.

Other rare genetic causes of antithrombin deficiency have also been identified. These include mutations in other genes and proteins associated with the clotting process. However, these genetic causes are less common and may require additional testing or research studies.

For more information about hereditary antithrombin deficiency and other rare clotting disorders, you can visit the OMIM (Online Mendelian Inheritance in Man) website, where you can find a catalog of diseases with related articles and research studies.

Learn more about the gene associated with Hereditary antithrombin deficiency

Hereditary antithrombin deficiency is a rare genetic condition characterized by a deficiency of the antithrombin protein, which plays a crucial role in regulating blood clotting. People with this condition have an increased risk of developing abnormal blood clots.

The gene associated with Hereditary antithrombin deficiency is called SERPINC1. This gene provides instructions for making the antithrombin protein. Mutations in the SERPINC1 gene can lead to a reduction or complete absence of functional antithrombin protein, resulting in the development of this condition.

In addition to hereditary antithrombin deficiency, mutations in the SERPINC1 gene can also cause other types of thrombophilia, which are conditions that increase the risk of abnormal blood clotting.

If you or someone you know has been diagnosed with Hereditary antithrombin deficiency, it is important to learn more about the genetic causes of this condition. By understanding the specific genes involved, researchers can develop better diagnostic tools and treatment options.

There are several resources available to learn more about the SERPINC1 gene and Hereditary antithrombin deficiency:

• OMIM: The Online Mendelian Inheritance in Man (OMIM) is a catalog of human genes and genetic disorders. You can find information about the SERPINC1 gene and related conditions on the OMIM website.

Inheritance

Hereditary antithrombin deficiency is caused by mutations in the SERPINC1 gene, which provides instructions for making the antithrombin III protein. These mutations can be inherited in an autosomal dominant manner, meaning that a person only needs to inherit one copy of the mutated gene to develop the condition.

This genetic condition is rare, with a frequency of about 1 in 2,000 to 5,000 individuals in the general population. The type and severity of the deficiency can vary among affected individuals.

When a person has hereditary antithrombin deficiency, their blood’s ability to clot is affected. Antithrombin III is a protein that plays a key role in regulating the formation of blood clots. With reduced or nonfunctional antithrombin III, the risk of developing abnormal blood clots, such as deep vein thrombosis or pulmonary embolism, is increased.

Hereditary antithrombin deficiency can be diagnosed through genetic testing, which can detect mutations in the SERPINC1 gene. This testing may be recommended for individuals with a family history of the condition or for those who have experienced blood clots at a young age.

Inheritance of hereditary antithrombin deficiency follows an autosomal dominant pattern, which means that each child of an affected individual has a 50% chance of inheriting the condition. However, not all individuals who inherit the gene mutation will develop symptoms or even have reduced antithrombin III levels.

For more information about hereditary antithrombin deficiency, there are online resources available, such as the Online Mendelian Inheritance in Man (OMIM) database and scientific articles on PubMed. Additionally, organizations like the Hereditary Antithrombin Deficiency Research and Advocacy Center provide support, research, and additional information about this rare genetic condition.
