The SMARCA2 gene, also known as the SWI/SNF-related, matrix-associated, actin-dependent regulator of chromatin, subfamily a, member 2, is a gene that has been identified as a potential risk factor for certain conditions. It is located in the chromosomal region 9p24.1 and is involved in the regulation of gene expression. Changes in the SMARCA2 gene have been found to be associated with a variety of conditions, including Nicolaides-Baraitser syndrome and other related syndromes.

Information about the SMARCA2 gene and its related conditions can be found in various scientific databases and resources. PubMed, a widely used database for scientific articles, has published a number of articles discussing the role of the SMARCA2 gene in different diseases and conditions. The Online Mendelian Inheritance in Man (OMIM) database also provides information on the SMARCA2 gene and its associated disorders.

In addition to these databases, there are other resources available for further information and testing. The Genetic Testing Registry (GTR) lists genetic tests that can be performed on the SMARCA2 gene to assess the risk of developing certain conditions. These tests can provide important information for individuals and their healthcare providers regarding their genetic health and the potential risk of developing certain cancers, such as neck and related cancers.

It is important to note that changes in the SMARCA2 gene can result in different variants of the protein it codes for. These protein variants can have different effects on gene expression and may contribute to the development of certain diseases. Testing for these gene variants can provide valuable information for individuals and their healthcare providers in assessing their risk for certain conditions and determining appropriate treatments and preventive measures.

The SMARCA2 gene is associated with various health conditions when certain genetic changes occur. These changes can increase the risk of developing certain diseases or disorders. Here are some of the health conditions related to genetic changes in the SMARCA2 gene:

Nicolaides-Baraitser Syndrome

Nicolaides-Baraitser syndrome is a rare genetic disorder caused by changes in the SMARCA2 gene. This condition affects the development of the brain, causing intellectual disability, seizures, and distinctive facial features.

For both workers and companies, employer-sponsored health insurance is costly. For 2018, employers paid an average of $10,000 per employee to cover 70% of the cost of health insurance, leaving workers with a price tag of about $4,200 for the remaining 30% of the expense, CNBC

Risk for Cancers

Genetic changes in the SMARCA2 gene have been found to increase the risk of certain types of cancers, such as lung and neck cancers. Smokers with these genetic changes may have a higher risk of developing these cancers.

Other Health Conditions

In addition to Nicolaides-Baraitser syndrome and the increased risk of certain cancers, genetic changes in the SMARCA2 gene may be associated with other health conditions. However, more research is needed to fully understand the extent of this relationship.

Genetic Testing and Resources

If you suspect a genetic change in the SMARCA2 gene or want to learn more about these health conditions, genetic testing can provide valuable information. Testing for changes in specific nucleotides or proteins can help identify the presence of genetic variations related to these conditions. Here are some resources for more information and testing:

  • OMIM (Online Mendelian Inheritance in Man) – an online catalog of human genes and genetic disorders
  • PubMed – a database of scientific articles and references
  • National Institutes of Health Genetic Testing Registry – a comprehensive registry of genetic tests

It is important to consult a healthcare professional for more information and guidance on genetic testing for SMARCA2 gene-related conditions. They can provide personalized advice based on your specific situation and help interpret the results.

Nicolaides-Baraitser syndrome

Nicolaides-Baraitser syndrome is a genetic condition caused by changes in the SMARCA2 gene, located on chromosome 9. This gene provides instructions for making a protein that plays a critical role in regulating the activity of other genes.

The condition is characterized by intellectual disability, distinctive facial features, sparse scalp hair, thick eyebrows, anteverted nares, prominent upper central incisors, a wide mouth, and a pointed chin. It is also associated with a wide range of additional features, including seizures, behavioral problems, and developmental delays.

To diagnose Nicolaides-Baraitser syndrome, genetic testing can be performed to identify changes in the SMARCA2 gene. This can usually be done through targeted gene sequencing or by testing for specific changes known to be associated with the syndrome. Further testing may be necessary to confirm the diagnosis in individuals with atypical symptoms.
