The CHRNE gene, also known as cholinergic receptor nicotinic epsilon subunit, is a gene that is responsible for encoding a protein involved in the formation of a subtype of cholinergic receptors. Cholinergic receptors are found at nerve endings and are involved in transmitting signals between nerve cells. The CHRNE gene is part of a larger family of genes that encode subunits of cholinergic receptors.
There are several known mutations and changes in the CHRNE gene that are associated with various congenital myasthenic syndromes, which are a group of genetic disorders characterized by muscle weakness and fatigue. These conditions result from a decrease in the number or function of cholinergic receptors at the nerve-muscle junction.
The CHRNE gene is listed in various genetic databases and resources, such as OMIM, the Online Mendelian Inheritance in Man database. This database provides detailed information on the genetic changes and mutations associated with the CHRNE gene, as well as additional genetic and health-related information.
Scientific articles, references, and resources on the CHRNE gene and its related conditions can be found in several databases, including PubMed. PubMed is a comprehensive database of scientific publications and provides access to a wide range of articles and research findings on the CHRNE gene and its role in various diseases and disorders.
Genetic testing for mutations in the CHRNE gene can be performed to diagnose and confirm the presence of congenital myasthenic syndromes. This testing can help in providing accurate diagnoses, as well as in guiding treatment and management strategies for individuals affected by these conditions.
In conclusion, the CHRNE gene plays a crucial role in the formation and function of cholinergic receptors, and its mutations and changes are associated with various congenital myasthenic syndromes. The gene is extensively studied and documented in scientific databases and resources, providing valuable information for researchers, healthcare professionals, and individuals affected by these genetic conditions.
Americans see their primary care doctors less often than they did a decade ago. Adults under 65 made nearly 25% fewer visits to primary care providers in 2016 than they did in 2018, according to National Public Radio. In the same time period, the number of adults who went at least a year without visiting a primary care provider increased from 38% to 46%.
Health Conditions Related to Genetic Changes
Genetic changes in the CHRNE gene can lead to various health conditions. The CHRNE gene encodes the subunit epsilon of the nicotinic acetylcholine receptor (AChR) on the muscle side of the neuromuscular junction. This receptor is responsible for receiving signals from nerve cells and initiating muscle contractions.
Changes in the CHRNE gene can result in myasthenic syndromes, which are a group of genetic disorders characterized by muscle weakness and fatigue. These conditions can be congenital (present at birth) or acquired later in life. Testing for specific CHRNE gene mutations can provide additional information for diagnosing these myasthenic syndromes.
The CHRNE gene is associated with various diseases and conditions. Some of these include:
- Congenital myasthenic syndrome
- Slow-channel congenital myasthenic syndrome
- Fetal akinesia deformation sequence
- Myasthenic syndrome, fast-channel congenital
- Myasthenic syndrome, congenital, associated with acetylcholine receptor deficiency
- Multiple pterygium syndrome, lethal type
For more information on these conditions and genetic testing options, references to scientific articles, and other resources, the following databases can be consulted:
- Online Mendelian Inheritance in Man (OMIM)
- PubMed
- Myasthenia Gravis Genetic and Rare Diseases Information Center
- Myasthenia Gravis Foundation of America
- Catalog of Human Genes and Genetic Disorders (GeneCards)
Genetic changes in the CHRNE gene can lead to a decrease in the number or function of the nicotinic acetylcholine receptor. This results in impaired transmission of nerve signals at the neuromuscular junction, leading to muscle weakness and fatigue.
In conclusion, genetic changes in the CHRNE gene can give rise to various health conditions, including myasthenic syndromes and fetal akinesia deformation sequence. Understanding these genetic changes can help in diagnosing and managing these conditions.
Congenital myasthenic syndrome
Congenital myasthenic syndrome (CMS) is a genetic disorder that affects the function of the cholinergic receptors at the neuromuscular junction. It is characterized by a decrease in the number or function of these receptors, resulting in muscle weakness and fatigue.
There are multiple subtypes of CMS, with mutations in different genes encoding for the cholinergic receptor subunits. These subunits include CHRNA1, CHRNB1, CHRND, CHRNE, and CHRNG. Mutations in the CHRNE gene are associated with a specific subtype of CMS known as CMS with acetylcholine receptor deficiency.
CMS can present in both children and adults, with symptoms ranging from mild to severe. Common symptoms include muscle weakness, difficulty with motor skills, and respiratory problems. In some cases, symptoms may worsen with physical activity or stress.
Diagnosis of CMS typically involves a comprehensive clinical evaluation, nerve conduction testing, and genetic testing. The Myasthenia Gravis and Related Disorders International Registry is a valuable resource for information and resources related to CMS and other myasthenic conditions.
There are scientific articles and genetic databases available that provide information on the CHRNE gene and its related mutations. Examples of these resources include PubMed, OMIM, and the Catalog of Genes and Genetic Diseases. PubMed offers a wide range of articles and references on CMS and CHRNE gene mutations. OMIM provides detailed information on genetic changes associated with CMS and related conditions. The Catalog of Genes and Genetic Diseases lists all known genes associated with CMS and other genetic conditions.
Overall, CMS is a complex genetic disorder that affects the neuromuscular junction. Understanding the genetic changes associated with CMS and the role of the CHRNE gene allows for better diagnosis, testing, and management of this condition.
