The ITGB3 gene is a gene that is only found in humans. It is located within the Glanzmann thrombasthenia (GT) blood clotting disorder. This gene is responsible for the production of the beta3 subunit of the glycoprotein IIb/IIIa complex on the surface of platelets. Variants in the ITGB3 gene can lead to functional changes, which can result in platelet-type bleeding disorders or other related conditions.

Information about the ITGB3 gene can be found in various scientific databases, such as OMIM and PubMed. These resources provide additional references and articles on the genetic changes associated with this gene, as well as rare disorders and conditions listed in their catalog. The ITGB3 gene is formed by the combination of two other genes, ITGA2B and ITGB3, which are related to blood clot formation and normal platelet function.

Testing for variants in the ITGB3 gene can be done to diagnose thrombasthenia or other platelet-related disorders. This testing can help identify changes in the gene that may affect its function and lead to abnormal clot formation. The ITGB3 gene registry is a database that collects information on people with known variants in this gene, providing valuable resources for researchers and healthcare professionals.

Genetic changes in the ITGB3 gene can lead to various health conditions. The ITGB3 gene is responsible for producing a glycoprotein called integrin beta-3, which is involved in the formation of blood clots.

One health condition related to genetic changes in the ITGB3 gene is Glanzmann thrombasthenia. This is a rare disorder characterized by a deficiency or dysfunction of the integrin beta-3 protein. People with Glanzmann thrombasthenia may experience abnormal bleeding, easy bruising, and prolonged bleeding time.

Another health condition related to genetic changes in the ITGB3 gene is platelet-type thrombasthenia. This is a rare variant of Glanzmann thrombasthenia, in which the integrin beta-3 protein is produced but is dysfunctional. People with this variant exhibit similar symptoms to Glanzmann thrombasthenia.

Preventable medical errors kill about 22,000 patients a year, according to research from the Yale School of Medicine. That’s much less than a previously reported number of 250,000 deaths a year where medical error is to blame.

Additional health conditions associated with genetic changes in the ITGB3 gene may exist, but they are not yet well-documented in scientific articles. Therefore, further research is needed to understand the full extent of the impact of ITGB3 gene mutations on human health.

For more information on health conditions related to genetic changes in the ITGB3 gene, resources such as OMIM (Online Mendelian Inheritance in Man), PubMed, and other scientific databases can be consulted. These resources provide references to articles and studies that contain valuable information on these conditions.

Testing for genetic changes in the ITGB3 gene can be done through genetic testing laboratories and clinics. These tests can help diagnose conditions such as Glanzmann thrombasthenia and platelet-type thrombasthenia. Genetic testing can also be useful for identifying carriers of these conditions and for providing information on the risk of passing them on to future generations.

In conclusion, genetic changes in the ITGB3 gene can result in various health conditions related to the formation of blood clots. Glanzmann thrombasthenia and platelet-type thrombasthenia are two disorders associated with genetic changes in this gene. Further research is needed to fully understand the impact of ITGB3 gene mutations on human health and to identify any additional related conditions.

Glanzmann thrombasthenia

Glanzmann thrombasthenia is a rare blood disorder caused by changes (variants) in the ITGB3 gene. It is also known as platelet-type von Willebrand disease (PT-VWD). Glanzmann thrombasthenia is characterized by a functional defect in the glycoprotein IIb/IIIa (GPIIb/IIIa) complex on the surface of platelets, which is essential for clot formation.

In people with Glanzmann thrombasthenia, platelets are unable to bind to each other and form clots properly. This can result in prolonged bleeding, particularly after injuries or surgeries. Glanzmann thrombasthenia is inherited in an autosomal recessive manner, meaning that both copies of the ITGB3 gene must have variants in order to develop the disorder.

The ITGB3 gene provides instructions for making a protein called integrin β3. This protein is part of the GPIIb/IIIa complex on the surface of platelets. Variants in the ITGB3 gene can lead to a partial or complete loss of function of the GPIIb/IIIa complex, preventing normal clot formation.

Tests for Glanzmann thrombasthenia can be done through genetic testing, which can identify variants in the ITGB3 gene. Diagnosis is often confirmed by functional testing of platelet aggregation. Additional testing may be done to rule out other disorders with similar symptoms, such as von Willebrand disease or other platelet disorders.

Glanzmann thrombasthenia is a rare condition, with an estimated incidence of 1 in 1 million individuals. It has been reported in individuals of various ethnic backgrounds.

Osteopetrosis

Osteopetrosis is a rare genetic disorder characterized by an abnormal increase in bone density. It is caused by mutations in genes that are involved in the normal reabsorption and remodeling of bone. One of the genes associated with osteopetrosis is the ITGB3 gene, which codes for the integrin beta 3 subunit.

Integrin beta 3 is a protein that is found on the surface of platelets, which are responsible for blood clotting. Mutations in the ITGB3 gene can lead to a variant of osteopetrosis called osteopetrosis with thrombasthenia. Thrombasthenia is a rare platelet disorder characterized by a decreased ability of platelets to form clots.

Individuals with osteopetrosis may experience a variety of symptoms, ranging from mild to severe. These can include skeletal abnormalities, such as fractures and deformities, as well as problems with vision, hearing, and other complications. Diagnosis of osteopetrosis is often based on clinical symptoms, radiographic tests, and genetic testing.

There are several resources available for individuals and healthcare providers seeking more information on osteopetrosis. The Online Mendelian Inheritance in Man (OMIM) database provides a comprehensive catalog of genes and genetic disorders, including osteopetrosis. PubMed is another valuable resource for scientific articles and research related to this condition.

In addition to the ITGB3 gene, other genes such as ITGA2B and ITGB3 are also associated with platelet-related conditions like Glanzmann thrombasthenia. These genes play a role in the formation and function of platelets.

Overall, osteopetrosis is a rare disorder characterized by abnormal bone density, and it can be caused by mutations in genes such as ITGB3. Genetic testing and other diagnostic tests can help confirm a diagnosis, and resources like OMIM and PubMed can provide further information and references for healthcare professionals and individuals affected by this condition.

Other disorders

Within the ITGB3 gene, rare genetic conditions can arise from variations, which can lead to different disorders. One such condition is osteopetrosis, also called the “marble bone disease,” where bones become abnormally dense and prone to fractures.

Another variant of thrombasthenia, known as the Glanzmann thrombasthenia (GT), is formed due to variations in the ITGA2B gene, which is closely related to the ITGB3 gene. GT is a rare platelet-type bleeding disorder that affects the function of glycoprotein IIb/IIIa, leading to abnormal blood clot formation.

To further explore these conditions and related disorders, several scientific catalogs and databases provide extensive information, along with references and articles. PubMed and OMIM are two well-known resources for genetic information, where researchers can find additional articles on these rare disorders.

The ITGB3 gene is not the only gene associated with platelet functional disorders. Other genes such as ITGA2B and GP1BA have also been linked to similar blood clotting abnormalities. To diagnose these disorders, genetic testing can be performed to identify changes within these genes.

For people undergoing genetic testing for thrombasthenia or other related disorders, it is essential to consult with healthcare professionals to understand their health implications and potential treatment options. Additional resources like the Platelet Research and Registry provide support and information for individuals and families affected by these conditions.
