The CHRNA2 gene, also known as the cholinergic receptor nicotinic alpha 2 subunit gene, is listed in the OMIM database. It is a rare genetic variant associated with certain diseases, including epilepsy. The CHRNA2 gene encodes proteins that are part of the neuronal receptors for the neurotransmitter acetylcholine, specifically the alpha 2 subunits.

Research has shown that changes in the CHRNA2 gene can lead to altered function and expression of these receptors, allowing for abnormal neuronal activity in the brain. This can contribute to the development of conditions like epilepsy and other neurological disorders.

Genetic testing can be done to identify variants in the CHRNA2 gene, providing valuable information for both scientific research and clinical practice. Testing for these genetic changes can be particularly important in cases of autosomal dominant nocturnal epilepsy, a condition that has been linked to specific mutations in the CHRNA2 gene.

There are various resources and databases available that provide additional information and references on the CHRNA2 gene and related topics. PubMed, a popular scientific database, contains numerous articles and studies on this gene and its involvement in various diseases. The OMIM database is another valuable resource that catalogs genetic disorders and provides detailed information on genes, variants, and associated conditions.

In conclusion, the CHRNA2 gene plays an essential role in the development and function of neuronal receptors for the neurotransmitter acetylcholine. Variants in this gene have been linked to conditions such as epilepsy, and research on these genetic changes can provide valuable insights into the underlying mechanisms of these diseases. Genetic testing and databases like PubMed and OMIM are essential tools in understanding the CHRNA2 gene and its implications in health and disease.

Health Conditions Related to Genetic Changes

Rare genetic changes in the CHRNA2 gene are associated with various health conditions. The CHRNA2 gene provides instructions for making a protein called neuronal acetylcholine receptor subunit alpha-2. This protein is part of a larger protein complex called the acetylcholine receptors, which are located on the surface of neurons.

Though opponents of a single-payer system have long cited cost as an obstacle, findings published in The Lancetshow the opposite is true. Switching from the current model of numerous public and private insurers to a Medicare for All model would save the United States 13% annually. In raw numbers, that’s $450 billion a year.

Genetic changes in CHRNA2 can lead to alterations in the structure or function of the neuronal acetylcholine receptor subunit alpha-2 protein. These changes can affect the normal transmission of signals between neurons, causing disruptions in the activity of neurotransmitters like acetylcholine.

One specific genetic variant identified in the CHRNA2 gene is known as the CHRNA2 E4P variant. This variant is found in people with autosomal dominant nocturnal frontal lobe epilepsy (ADNFLE), a rare form of epilepsy characterized by seizures that occur during sleep.

Additional health conditions related to genetic changes in the CHRNA2 gene are still being studied, and research is ongoing. Some of these conditions may include other forms of epilepsy, psychiatric disorders, and neurodevelopmental disorders. The specific effects of genetic changes in CHRNA2 can depend on the specific variant involved and other genetic and environmental factors.

If you are interested in learning more about the health conditions related to genetic changes in the CHRNA2 gene, additional information can be found in scientific articles and databases. The OMIM (Online Mendelian Inheritance in Man) database is a valuable resource that provides comprehensive information on genetic diseases, including those related to the CHRNA2 gene. The CHRNA2 gene is also listed in various genetic testing resources, such as the Genetic Testing Registry (GTR), which provide information on available tests for genetic conditions.

Autosomal dominant nocturnal frontal lobe epilepsy

Autosomal dominant nocturnal frontal lobe epilepsy (ADNFLE), also called autosomal dominant sleep-related hypermotor epilepsy (ADSHE), is a rare genetic condition that affects the frontal lobe of the brain. This form of epilepsy is characterized by seizure episodes that occur primarily during sleep.

The CHRNA2 gene, which encodes for proteins called subunits of nicotinic acetylcholine receptors, plays a role in ADNFLE. These receptors are found on neurons in the frontal lobe and are involved in the transmission of the chemical neurotransmitter acetylcholine. Mutations or changes in the CHRNA2 gene can affect the function of these receptors, leading to the development of ADNFLE.

Genetic testing can be done to identify variants in the CHRNA2 gene that are associated with ADNFLE. This information can be used for diagnostic purposes and to determine the risk of passing on the condition to future generations. Additional research and scientific studies are ongoing to further understand the role of the CHRNA2 gene and its relationship to ADNFLE.

ADNFLE is inherited in an autosomal dominant pattern, which means that a person only needs to inherit one copy of the altered gene from one parent to develop the condition. However, not all individuals with a genetic variant in the CHRNA2 gene will experience symptoms of ADNFLE.

There are other related conditions and diseases that are also associated with genetic changes in the CHRNA2 gene. These conditions include other forms of epilepsy and neurological disorders.

Resources for information and support for individuals with ADNFLE and their families can be found in scientific articles, genetic databases, and health registries. Some of these resources include PubMed, OMIM, and genetic testing catalogs.
