ACVRL1 gene

The ACVRL1 gene, also known as ALK-1 (Activin A receptor type II-like kinase 1), is a gene that encodes a protein involved in the development and growth of blood vessels. It is one of the genes listed in the Genetic Testing Registry (GTR) that is associated with hereditary hemorrhagic telangiectasia (HHT) and pulmonary arterial hypertension (PAH).

HHT and PAH are both hereditary disorders characterized by abnormal blood vessel changes. Mutations in the ACVRL1 gene can result in variations of this protein, leading to the development of these diseases. Scientific articles and additional information on the ACVRL1 gene can be found on PubMed, OMIM, and other resources.

Genetic testing for mutations in the ACVRL1 gene can be done to diagnose HHT and PAH. Testing may also help identify other related genes and protein variants that contribute to the development of these diseases. The Gene Tests database provides information on available tests and links to laboratories offering genetic testing for ACVRL1 and other related genes.

For more information on the ACVRL1 gene, hereditary hemorrhagic telangiectasia, pulmonary arterial hypertension, and related genes, the HHT Foundation International and the Pulmonary Hypertension Association offer resources, references, and support for individuals and families affected by these conditions.

Health Conditions Related to Genetic Changes

Scientific research has identified several health conditions that are related to genetic changes in the ACVRL1 gene. These genetic changes can result in the development of hereditary hemorrhagic telangiectasia (HHT) and pulmonary arterial hypertension (PAH).

HHT, also known as Osler-Weber-Rendu syndrome, is a hereditary disorder characterized by abnormal blood vessel formation. It can lead to symptoms such as nosebleeds, telangiectasias (small, dilated blood vessels near the surface of the skin), and arteriovenous malformations (abnormal connections between arteries and veins).

PAH is a type of high blood pressure that affects the arteries in the lungs. Genetic changes in the ACVRL1 gene can cause an overgrowth of smooth muscle cells in the pulmonary arteries, leading to their narrowing and increased blood pressure. This can result in symptoms such as shortness of breath, fatigue, and chest pain.

Additional genes have also been identified as causing hereditary hypertension, growth disorders, and other related conditions. These genes include ALK-1 and ENG.

To diagnose these genetic conditions, genetic testing can be done. Various resources are available for testing, including databases such as OMIM and PubMed, which provide information on genetic changes, associated health conditions, and relevant scientific articles. The Human Gene Mutation Database and ClinVar catalog genetic variants and their clinical significance. The Genetic Testing Registry lists tests available for different genes and provides information on their purpose, methodology, and limitations.

Health organizations and clinics that specialize in these conditions can provide additional information and support. Genetic counselors can help individuals and families understand the implications of genetic changes and make informed decisions about testing and management strategies.

Hereditary hemorrhagic telangiectasia

Hereditary hemorrhagic telangiectasia, also known as HHT or Osler-Weber-Rendu syndrome, is a genetic condition that affects blood vessel development and can lead to the formation of abnormal blood vessels.

HHT is caused by changes in the ACVRL1 gene, also known as the ALK-1 gene. This gene provides instructions for making a protein involved in the growth and development of blood vessels. Changes in the ACVRL1 gene can disrupt the normal function of this protein, leading to the development of abnormal blood vessels.

Individuals with HHT may develop telangiectasia, which are small, tangled blood vessels near the surface of the skin or mucous membranes. Telangiectasia can cause recurrent nosebleeds and other bleeding symptoms. In addition, individuals with HHT are at an increased risk for arterial hypertension and can develop pulmonary arterial hypertension, which is high blood pressure in the arteries of the lungs.

The diagnosis of HHT is based on clinical features and can be confirmed by genetic testing. Genetic testing can identify changes in the ACVRL1 gene that are associated with HHT. Testing can be done through commercial laboratories or research laboratories and is usually only available for research purposes or in specialized HHT centers.

Additional information on HHT, including specific genetic variants and related conditions, can be found in online resources such as the HHT Foundation International and the HHT Mutation Database. These resources provide information and references to scientific articles, databases, and registries related to HHT and the ACVRL1 gene.

For health care professionals, the Online Mendelian Inheritance in Man (OMIM) database provides comprehensive information on the ACVRL1 gene and its associated conditions, including HHT. PubMed, a database of scientific articles, can also be searched for additional information on HHT and the ACVRL1 gene.

In summary, hereditary hemorrhagic telangiectasia is a genetic condition that affects blood vessel development and can cause telangiectasia, arterial hypertension, and pulmonary arterial hypertension. Changes in the ACVRL1 gene are responsible for HHT, and genetic testing can be used to confirm the diagnosis. Online resources and databases provide additional information and references for further research on HHT and the ACVRL1 gene.

Pulmonary arterial hypertension

Pulmonary arterial hypertension (PAH) is a condition characterized by high blood pressure in the arteries of the lungs. It is often caused by genetic changes in the ACVRL1 gene, also known as the ALK-1 gene. This gene provides instructions for making a protein that is important for the development and growth of blood vessels.

PAH can be inherited in an autosomal dominant pattern, which means one copy of the altered ACVRL1 gene in each cell is sufficient to cause the disorder. However, some cases of PAH are not inherited and occur in people with no family history of the condition.

There are several tests available to diagnose PAH, including genetic testing to identify changes in the ACVRL1 gene. This genetic testing can be done to confirm a diagnosis and to determine if other family members are at risk.

The ACVRL1 gene is also listed in various databases of genetic variation and diseases. Additional information on this gene, including its role in other conditions such as hereditary hemorrhagic telangiectasia, can be found in scientific articles and resources like OMIM, PubMed, and the Human Gene Mutation Database.

The Registry to Evaluate Early and Long-term Pulmonary Arterial Hypertension Disease Management (REVEAL Registry) is a comprehensive US-based registry that collects information on patients with PAH to improve the understanding and management of the disease. This registry provides valuable information for researchers, patients, and healthcare providers.

In conclusion, pulmonary arterial hypertension is a condition related to genetic changes in the ACVRL1 gene. It can be diagnosed through various tests, including genetic testing. Additional information on this gene and related disorders can be found in scientific articles and resources like OMIM and PubMed.
