The NR3C2 gene, also known as the nuclear receptor subfamily 3, group C, member 2 gene, is associated with various genetic disorders related to the regulation of sodium reabsorption in the kidneys. This gene plays a crucial role in the control of sodium balance in the body.

These disorders include pseudohypoaldosteronism type 1, a condition characterized by salt loss, hyponatremia (low sodium levels), and hyperkalemia (high potassium levels). Mutations in the NR3C2 gene can disrupt the normal function of proteins involved in sodium reabsorption and lead to the development of these diseases.

The NR3C2 gene is listed in various databases and resources for genetic testing and research, such as OMIM (Online Mendelian Inheritance in Man) and the Molecular Catalog of Testing. These resources provide additional information on the gene, its variants, and associated diseases.

Scientific articles and references on the NR3C2 gene can be found in databases such as PubMed, providing further insights into its molecular function, role in disease development, and potential therapeutic targets. Specialized tests and registries are available for the diagnosis and management of conditions related to NR3C2 gene mutations during pregnancy and throughout life.

Genetic changes in the NR3C2 gene can lead to various health conditions and disorders. NR3C2 is a member of the nuclear receptor superfamily and plays a crucial role in the regulation of sodium reabsorption in cells.

One health condition related to genetic changes in the NR3C2 gene is pseudohypoaldosteronism type 1 (PHA1). This condition is characterized by hyponatremia (low blood sodium levels) and salt-wasting. PHA1 can be inherited in an autosomal recessive or dominant manner, depending on the specific gene mutations involved.

Inflated pharmaceutical prices are another huge factor in the steep cost of healthcare. Americans spend an average of $858 per person on prescription drugs, according to Vox. That’s about twice as much as people in Australia spend on prescriptions. It’s three times the amount paid by people in The Netherlands.

Individuals with PHA1 may have symptoms such as dehydration, vomiting, failure to thrive, and developmental delays. Treatment typically involves careful salt and fluids management, as well as genetic testing to confirm the diagnosis.

Genetic changes in the NR3C2 gene can also worsen the condition of patients with other diseases or disorders, such as hypertension and pregnancy-induced hypertension. These changes can affect the regulation of sodium reabsorption and lead to imbalances in the body.

For more information on health conditions related to genetic changes in the NR3C2 gene, you can refer to scientific articles, specialized resources, and databases, such as OMIM (Online Mendelian Inheritance in Man) and PubMed.

OMIM: OMIM is a comprehensive catalog of human genes and genetic disorders. It provides detailed information on the NR3C2 gene and related conditions.
PubMed: PubMed is a database of scientific articles and references. It can be used to find research studies and publications on the NR3C2 gene and its associations with health conditions.

Additionally, genetic testing can be conducted to identify specific gene mutations and variants related to these conditions.

Pseudohypoaldosteronism type 1

Pseudohypoaldosteronism type 1 (PHA1) is a rare genetic condition characterized by impaired regulation of sodium reabsorption in the kidneys, leading to hyponatremia (low sodium levels) and other electrolyte imbalances.

PHA1 is caused by mutations in the NR3C2 gene, also known as the mineralocorticoid receptor gene. This gene provides instructions for making a protein that plays a key role in the control of electrolyte balance in the body. Mutations in the NR3C2 gene can disrupt the normal function of this protein, leading to abnormalities in sodium and potassium reabsorption in kidney cells.

There are two forms of PHA1: autosomal dominant PHA1 (AD PHA1) and autosomal recessive PHA1 (AR PHA1). AD PHA1 is caused by mutations in the NR3C2 gene, while AR PHA1 is caused by mutations in another gene called SCNN1A. Both forms of PHA1 result in similar symptoms and can be associated with severe dehydration, failure to thrive, and developmental delays.

Other disorders

The NR3C2 gene is also involved in several other disorders. Here are some additional resources and information on these conditions:

Pseudohypoaldosteronism type 1 (PHA1): This condition is characterized by salt-wasting, hyponatremia, and hyperkalemia. Mutations in the NR3C2 gene can lead to the development of this disorder. Additional information and resources on PHA1 can be found in specialized databases such as OMIM and PubMed.
Pseudohypoaldosteronism type 2 (PHA2): PHA2 is another form of pseudohypoaldosteronism that is caused by mutations in different genes involved in the regulation of sodium reabsorption. Although NR3C2 gene mutations are not directly associated with this condition, it is important to consider other genetic changes and related genes when testing for PHA2.
Related disorders: The NR3C2 gene plays a role in the molecular control of sodium reabsorption in specialized cells. Therefore, changes in this gene can also be related to other genetic conditions or diseases involving abnormal sodium regulation.

For additional scientific articles, health resources, and information on genetic testing for these and other disorders, it is recommended to consult relevant databases, catalogs, and references.
