TSEN54 gene – Austra Health

The TSEN54 gene is responsible for encoding a subunit of the tRNA splicing endonuclease, which is involved in the process of removing introns from transfer RNA (tRNA) precursors. This gene has been found to be associated with various diseases, including pontocerebellar hypoplasia.

Changes or mutations in the TSEN54 gene can lead to the production of an abnormal protein or a loss of function, which in turn affects the splicing of tRNA precursors. Most of the mutations identified in this gene have been found in patients with pontocerebellar hypoplasia, a condition characterized by underdevelopment of the brain structures called the pons and cerebellum.

Additional information about the TSEN54 gene can be found in various scientific databases, such as OMIM, PubMed, and GenBank. These resources provide information on the genetic function of the gene, associated diseases and conditions, testing methods, and related articles. The TSEN54 gene is listed in the OMIM catalog with the entry number 609450.

Testing for mutations in the TSEN54 gene can be performed to confirm a diagnosis of pontocerebellar hypoplasia or to assess the risk of passing on the condition to future generations. Genetic testing can also provide valuable information for healthcare professionals and affected individuals about potential treatment options and disease management strategies.

In conclusion, the TSEN54 gene plays a crucial role in the process of tRNA splicing and has been implicated in the development of pontocerebellar hypoplasia. Understanding the function and mutations in this gene can provide important insights into the genetic basis of this condition and may lead to the development of targeted therapies and interventions.

Health Conditions Related to Genetic Changes

Genetic changes in the TSEN54 gene have been associated with various health conditions. These changes can affect the function of this gene and lead to the development of different diseases.

One of the common diseases related to TSEN54 gene changes is pontocerebellar hypoplasia type 2. This condition is characterized by underdevelopment (hypoplasia) of the pons and cerebellum, which are parts of the brain involved in the coordination of movements.

Genetic testing for changes in the TSEN54 gene can help diagnose pontocerebellar hypoplasia type 2. This testing can detect mutations or variants in the gene that may be responsible for the disease.

Additional resources for information on health conditions related to genetic changes in the TSEN54 gene can be found in scientific articles, databases, and registries. The Online Mendelian Inheritance in Man (OMIM) database, PubMed, and other genetic databases provide references to articles and information on these diseases.

Health conditions related to genetic changes in the TSEN54 gene can also be categorized into different types based on the specific changes in the gene. These types can include changes in the function of the TSEN54 gene, changes in the process of tRNA splicing or the number of tRNA copies, and changes in other genes involved in the same biological pathway or function.

In the scientific literature, these health conditions related to genetic changes in the TSEN54 gene may be referred to by different names. Some examples include namavar syndrome, pontocerebellar hypoplasia type 2, and 2q23.3 microdeletion syndrome. These names may vary depending on the specific features or characteristics of the disease.

Pontocerebellar hypoplasia

Pontocerebellar hypoplasia is a rare genetic condition characterized by underdevelopment of the pons and cerebellum, two important parts of the brain. It is associated with mutations in the TSEN54 gene.

The TSEN54 gene provides instructions for making a protein that is part of a complex involved in a process called nonsense-mediated mRNA decay. This process helps ensure that only high-quality proteins are produced in cells. Mutations in the TSEN54 gene impair the function of this complex, leading to the accumulation of abnormal proteins and the death of cells in the pons and cerebellum.

The symptoms of pontocerebellar hypoplasia vary depending on the specific genetic variant and other factors. Some common features include developmental delay, low muscle tone, problems with movement and coordination, difficulty with swallowing, and intellectual disability.

Genetic testing can confirm a diagnosis of pontocerebellar hypoplasia. Testing may identify mutations in the TSEN54 gene or other related genes. Testing may involve sequencing the gene to look for changes in the DNA code or analyzing the gene for changes in its function.

There are several resources available for additional information on pontocerebellar hypoplasia and related conditions. The Online Mendelian Inheritance in Man (OMIM) database provides a catalog of genes and genetic conditions, including detailed information on the TSEN54 gene and pontocerebellar hypoplasia.

In summary, pontocerebellar hypoplasia is a rare genetic condition caused by mutations in the TSEN54 gene. These mutations affect the function of the gene and lead to underdevelopment of the pons and cerebellum. Genetic testing is available to confirm a diagnosis, and there are several resources available for additional information and support for individuals with this condition.
