TSHB gene

The TSHB gene is a genetic information that provides instructions for making the beta subunit of the thyrotropin hormone. This hormone, along with the alpha subunit, is involved in the regulation of thyroid gland activity. Mutations in the TSHB gene can lead to hypothyroidism, a condition characterized by an underactive thyroid gland and a decrease in the production of thyroid hormones.

Secondary hypothyroidism can be caused by mutations in the TSHB gene. This variant of hypothyroidism is often present from birth and is usually more severe than the congenital variant caused by mutations in the TSHR gene. The TSHB gene is located on chromosome 1p13.3-p13.1, in the region of the brain known as the hypothalamus-pituitary-thyroid axis.

The TSHB gene has been studied extensively and there are numerous scientific articles and references related to its function and mutations. The Online Mendelian Inheritance in Man (OMIM) database provides additional information and references on the TSHB gene and related diseases. The OMIM gene entry for TSHB includes a summary of relevant scientific articles, a catalog of known mutations, and a registry of genetic testing resources. The TSHB gene is also listed in other scientific databases such as PubMed.

Genetic testing for mutations in the TSHB gene can be performed to confirm a diagnosis of hypothyroidism or other related conditions. The testing process involves analyzing a person’s DNA for specific changes or variants in the TSHB gene. The results of this testing can help healthcare providers determine the cause of the condition and develop an appropriate treatment plan.

In summary, the TSHB gene plays a crucial role in the production and regulation of thyroid hormones. Mutations in this gene can lead to hypothyroidism and other related conditions. There is a wealth of scientific information and resources available to further understand the function and impact of the TSHB gene on human health.

Administrative costs currently make up a major chunk of healthcare spending, especially in America. In fact, healthcare administrative spending accounts for 8% of the GDP in the U.S., or more than $1.485 trillion if looking at 2016 data. The cost of healthcare administration in other nations is just 3% of the GPD, on average, according to healthcare revenue news source RevCycleIntelligence.

Health Conditions Related to Genetic Changes

There are several health conditions that are related to genetic changes in the TSHB gene. These conditions can have various names and may affect different genes or subunits. The scientific community has identified these conditions through genetic tests and research articles.

One condition related to genetic changes in the TSHB gene is secondary hypothyroidism. This condition is also known as central hypothyroidism and it occurs when the brain does not produce enough thyroid-stimulating hormone (TSH) to regulate the production of thyroid hormones.

Other conditions related to genetic changes in the TSHB gene include growth hormone deficiency. Genetic mutations in this gene have been found to be associated with brain development and growth disorders. These conditions can be diagnosed through genetic testing.

For additional information on these genetic changes and related health conditions, there are several databases and resources available. The Online Mendelian Inheritance in Man (OMIM) is a comprehensive catalog of genetic diseases and provides references to scientific articles and other resources. The Genetic Testing Registry (GTR) provides information on available genetic tests for these conditions.

Congenital hypothyroidism

Congenital hypothyroidism is a genetic disorder that affects the growth and development of the brain, as well as the production of thyroid hormones. It is caused by mutations in the TSHB gene, which encodes the beta subunit of the thyrotropin hormone.

Genetic Changes: The TSHB gene mutations can lead to changes in the structure or function of the beta subunit of the thyrotropin hormone. These changes can disrupt the normal production of thyroid hormones, resulting in congenital hypothyroidism.

Secondary changes: Congenital hypothyroidism can also be caused by secondary changes in other genes or regions of the genome that are involved in the production or regulation of thyroid hormones.

Testing and Diagnosis: Diagnosis of congenital hypothyroidism can be made through genetic testing. This involves sequencing the TSHB gene and looking for any mutations or genetic variants that may be associated with the condition.

Citation: Additional information on congenital hypothyroidism can be found in scientific articles and publications available through resources such as PubMed, OMIM, and other genetic databases.

Registry and Catalog: The Congenital Hypothyroidism Registry and Genetic Testing Catalog provide further information on genetic mutations, variant testing, and related conditions.
