The BSND gene, also known as barttin, plays a crucial role in the function of the chloride channels CLC-Kb and CLC-Ka. These channels are responsible for the reabsorption of chloride ions in the kidneys, a process essential for maintaining electrolyte balance in the body. Mutations in the BSND gene can lead to a loss of function in these chloride channels, causing a condition known as Bartter syndrome.

Bartter syndrome is a group of rare genetic disorders that are characterized by defects in the renal tubules, leading to excessive salt and water excretion and subsequent electrolyte imbalances. This syndrome is named after Dr. Frederic Bartter, who first described it in the 1960s. The condition is typically diagnosed in infancy or early childhood and can result in symptoms such as polyuria, polydipsia, and failure to thrive.

In this article, we will explore the mechanisms by which mutations in the BSND gene can cause Bartter syndrome. We will also discuss the impact of these genetic changes on the health and function of the kidneys, as well as the potential implications for hearing and other related conditions. Additionally, we will provide a list of resources, databases, and scientific articles for further reading and reference, including the Online Mendelian Inheritance in Man (OMIM) catalog, PubMed, and the DFNB73 registry.

Understanding the genetic basis of Bartter syndrome and the role of the BSND gene is crucial for the development of diagnostic tests and potential treatments for this condition. By studying the specific changes in the BSND gene and its protein product barttin, researchers and clinicians can gain valuable insights into the underlying mechanisms of the disease and explore therapeutic options to improve the quality of life for individuals with this rare genetic disorder.

Genetic changes in the BSND gene have been associated with several health conditions. The BSND gene encodes a protein called barttin, which is essential for the function of a chloride channel called ClC-Kb. This channel plays a crucial role in the reabsorption of chloride ions in the kidneys and the inner ear.

One of the health conditions related to genetic changes in the BSND gene is Bartter syndrome, which is characterized by salt wasting, metabolic alkalosis, and hyperreninemic hyperaldosteronism. Bartter syndrome can be caused by various genetic changes, including variants in the BSND gene.

As of August 2020, the most expensive drug in America is Myalept, a drug used to treat leptin deficiency. A month’s worse of this drug costs $71, 306 per month, according to research from GoodRx. Myalept is known as an “orphan drug” because it’s intended to treat a rare disease.

Another health condition associated with genetic changes in the BSND gene is a type of nonsyndromic hearing loss called DFNB73. This condition is characterized by moderate to severe bilateral hearing loss from infancy. Genetic testing can identify changes in the BSND gene that are responsible for DFNB73.

For additional information on the health conditions related to genetic changes in the BSND gene, several resources can be consulted. The Online Mendelian Inheritance in Man (OMIM) database provides detailed information on the genetic basis, clinical features, and references to scientific articles for each condition. The Genetic Testing Registry (GTR) lists genetic tests available for these conditions and provides information on test availability, testing mechanisms, and laboratories offering the tests.

Furthermore, the PubMed database can be searched for additional articles on the mechanisms, function, and other related genes involved in these conditions. The ClinGen Gene-Disease Validity Curations catalog provides curated information on the clinical validity of genetic changes in the BSND gene and their association with the listed health conditions.

In summary, genetic changes in the BSND gene can lead to various health conditions, including Bartter syndrome and DFNB73. Genetic testing can help to identify these changes, and several databases and resources are available to provide more information and references on these conditions.

Bartter syndrome

Bartter syndrome is a genetic disorder related to the loss of function of the BSND gene. It is listed in the CLC-KB, the clc-ka and clc-kb, and the registry of non-syndromic hearing loss and DFNB73. Testing for this syndrome can be done through genetic tests.

Genes that are related to Bartter syndrome include BSND and CLC-KB. Changes or variants in these genes can cause the syndrome. The Bartter syndrome is caused by mutations in the BSND gene, which encodes barttin. Barttin is a beta-subunit for chloride reabsorb at the nephron. The loss of function of the BSND gene disrupts the normal reabsorption of chloride, leading to the features of Bartter syndrome.

Additional information on Bartter syndrome can be found in scientific databases and catalogs such as OMIM and PubMed. These references provide information on the syndrome, its genetic causes, related genes, and other clinical and genetic information. Articles and citations on Bartter syndrome can be found in these databases as well.

Nonsyndromic hearing loss

Nonsyndromic hearing loss refers to hearing loss that occurs in the absence of other symptoms or medical conditions. It is a genetic condition that can be inherited from one or both parents. This type of hearing loss can be caused by mutations in various genes, including the BSND gene.

The BSND gene, also known as Barttin, encodes a protein that is involved in the function of certain chloride channels in the inner ear. These channels are responsible for the reabsorption of chloride ions, which is crucial for the maintenance of normal hearing. Mutations in the BSND gene can lead to a disruption in chloride transport and result in nonsyndromic hearing loss.

There are different types of nonsyndromic hearing loss associated with BSND gene mutations, such as DFNB73 and Bartter syndrome, which is characterized by renal salt wasting and hypokalemic alkalosis. The DFNB73 variant of the BSND gene is specifically related to nonsyndromic hearing loss.

Genetic testing can be used to identify mutations in the BSND gene and provide valuable information regarding the cause of nonsyndromic hearing loss. This type of testing can be performed in individuals with a family history of hearing loss or in those who have been diagnosed with the condition.

In addition to the BSND gene, there are many other genes involved in the development and function of the auditory system. Genetic testing can help identify mutations in these genes as well, providing a comprehensive understanding of the genetic mechanisms underlying nonsyndromic hearing loss.

In this context, the OMIM (Online Mendelian Inheritance in Man) database is an excellent resource for information on genetic conditions and the genes associated with them. The BSND gene and its related disorders, such as DFNB73 and Bartter syndrome, can be found in the OMIM database, along with additional information on their clinical features and genetic mechanisms.

Other resources for genetic information and testing include scientific articles, databases, and registries. PubMed is a widely used database for scientific articles and references, and it can provide information on the latest research on genetic mechanisms and tests for nonsyndromic hearing loss.
