The POLR3B gene, also known as polymerase (RNA) III (DNA directed) polypeptide B, is responsible for encoding one of the subunits of RNA polymerase III, an enzyme involved in RNA synthesis. This gene is related to POLR3-related leukodystrophy, a genetic disorder that affects myelin, the protective covering of nerve fibers in the brain and spinal cord. Mutations in the POLR3B gene can lead to changes in the structure and function of RNA polymerase III, resulting in reduced production of myelin and causing the symptoms associated with this disease.
Additional information about the POLR3B gene can be found in scientific articles and databases such as PubMed, OMIM, and GeneCards. These resources provide references, articles, and registry information related to the gene and its associated diseases. Testing and genetic variant catalogs are also available for testing and identifying changes in the POLR3B gene that may be responsible for certain conditions.
Research on the POLR3B gene and its role in POLR3-related leukodystrophy and other diseases is ongoing. Scientists continue to study this gene to understand its function and the effects of mutations, as well as to develop potential treatments and interventions. The study of genes like POLR3B is crucial for advancing our knowledge of genetic diseases and improving the health and well-being of individuals affected by these conditions.
Health Conditions Related to Genetic Changes
The POLR3B gene encodes for the RNA polymerase III subunit B, which is essential for the proper functioning of the RNA polymerase III enzyme. Genetic changes in the POLR3B gene can lead to various health conditions.
Health conditions related to genetic changes in the POLR3B gene can be identified using genetic tests and documented in various scientific resources and databases. These databases include OMIM (Online Mendelian Inheritance in Man) and PubMed, among others.

Pol III-related leukodystrophy
Pol III-related leukodystrophy is a genetic condition that affects the production of myelin, which is the protective covering around nerve fibers in the brain and spinal cord. The condition is caused by mutations in the POLR3B gene, which provides instructions for making one of the subunits of an enzyme called RNA polymerase III.
RNA polymerase III is responsible for transcribing specific genes into molecules called transfer RNA (tRNA), which are involved in the production of proteins. Mutations in the POLR3B gene reduce the amount of functional RNA polymerase III, leading to a shortage of tRNA molecules. This shortage disrupts normal protein production, affecting the development and function of myelin.
Pol III-related leukodystrophy is a rare condition, and its exact prevalence is unknown. A registry called the POLR3-Related Leukodystrophy Registry is collecting information from individuals with this condition to better understand its natural history, how it is inherited, and how it progresses over time.
Diagnosis of Pol III-related leukodystrophy is made based on clinical features, brain imaging, and genetic testing. Genetic testing can identify changes (variants) in the POLR3B gene that are associated with the condition. Additional testing may be done to evaluate other genes or conditions that can cause similar symptoms.
Scientific articles and databases such as PubMed, OMIM, and Genet Tests provide information on the POLR3B gene, related diseases, and other genes involved in leukodystrophies. These resources can be used to find references and additional information on this condition.
The POLR3B gene is listed in the Online Mendelian Inheritance in Man (OMIM) catalog and the Genet Tests database as being associated with Pol III-related leukodystrophy. OMIM provides a summary of the gene, including its location, function, and associated diseases. Genet Tests provides information on available tests for this gene and associated conditions.
