This gene provides instructions for making an enzyme called adenosine deaminase 2, which is involved in the immune system response and the regulation of inflammation.

The ADA2 gene mutations inherited in an autosomal recessive pattern, meaning that both copies of the gene in each cell have mutations. In most cases, affected individuals inherit one mutated copy of the ADA2 gene from each parent, who are often unaffected carriers of the mutation.

There are various names for this condition, including “deficiency of ADA2,” “deficiency of adenosine deaminase 2,” “DADA2,” and “DADA2 vasculopathy.”

The frequency of ADA2 deficiency is not well established, but it is considered to be a rare genetic condition. It has been described in several populations around the world, including individuals of Turkish, Dutch, Japanese, and Italian descent.

ADA2 deficiency is associated with a range of symptoms and clinical features, including pro-inflammatory vasculopathy, hematologic abnormalities, and immunodeficiency. The condition can affect various tissues and organs, including the skin, joints, kidneys, and gastrointestinal system.

There are many scientific articles and resources available for more information about this condition. The OMIM database provides detailed information on the ADA2 gene, associated genetic disorders, and references to relevant scientific literature. PubMed is another valuable resource for accessing research articles on ADA2 deficiency and related topics.

The DADA2 Foundation and the National Center for Advancing Translational Sciences (NCATS) may provide additional support and information for patients and families affected by ADA2 deficiency.

Inheritance

Adenosine deaminase 2 deficiency (DADA2) is an autosomal recessive genetic disorder. This means that to develop the condition, an individual must inherit two copies of the defective gene, one from each parent.

DADA2 is caused by mutations in the ADA2 gene, which encodes the adenosine deaminase 2 enzyme. This enzyme plays a crucial role in regulating the immune system and preventing the accumulation of adenosine and deoxyadenosine, which are toxic to certain cells.

Individuals affected by DADA2 have mutations in both copies of the ADA2 gene, leading to a deficiency of the adenosine deaminase 2 enzyme. This deficiency results in dysregulated immune responses and inflammation, leading to the characteristic symptoms and features of the condition.

The inheritance pattern of DADA2 follows autosomal recessive inheritance. This means that individuals with one mutated ADA2 gene (carriers) typically do not show signs or symptoms of the condition, as they have one functional copy of the gene. However, carriers have a 50% chance of passing the mutated gene to their children.

To diagnose DADA2, genetic testing is typically performed to identify mutations in the ADA2 gene. This testing can be done using a blood or tissue sample from the patient. Genetic testing can confirm the diagnosis of DADA2 and help distinguish it from other diseases with similar symptoms.

For more information about DADA2, its inheritance, and associated symptoms, visit OMIM (Online Mendelian Inheritance in Man) or PubMed. These resources provide additional scientific articles and references on the condition. The National Center for Biotechnology Information (NCBI) and other genetic databases also catalog information about DADA2 and related genes.

Support and advocacy organizations, such as the ADA2 Deficiency Foundation and other patient support groups, can also provide resources and information for individuals and families affected by DADA2. These organizations can offer support, educational materials, and opportunities to connect with others facing similar challenges.

In summary, adenosine deaminase 2 deficiency is an autosomal recessive genetic condition. It is caused by mutations in the ADA2 gene and is associated with a deficiency of the adenosine deaminase 2 enzyme. To learn more about this rare genetic disease and its inheritance, consult reliable sources such as OMIM, PubMed, and support organizations.
