The PDHB gene is a gene that codes for the E1beta subunit of the pyruvate dehydrogenase complex. This complex is responsible for the conversion of pyruvate into acetyl-CoA, which is used in the citric acid cycle to produce energy. Mutations in the PDHB gene can lead to a genetic deficiency of the pyruvate dehydrogenase complex, resulting in a range of related conditions and diseases.

OMIM, Genet and PubMed are databases that contain information about genetic conditions. They provide resources such as scientific articles, references, and testing information for genes and variants associated with diseases. The PDHB gene is listed in these databases for the changes and variants that have been identified in patients with pyruvate dehydrogenase deficiency and related conditions.

In addition to the PDHB gene, there are other genes involved in the pyruvate dehydrogenase complex, including PDHA1, PDHX, and DLD. Mutations in any of these genes can cause deficiencies in the complex and lead to a variety of health problems. Leigh syndrome is one of the conditions associated with mutations in the PDHB gene and other genes of the complex.

Testing for mutations in the PDHB gene and other genes of the pyruvate dehydrogenase complex can be done through genetic testing. This testing can help in diagnosing and understanding the underlying causes of diseases and conditions related to pyruvate dehydrogenase deficiency. The results of genetic testing can provide important information for medical professionals and patients in making treatment decisions and managing the condition.

Genes, with various names, registry numbers, and databases, are important components of the scientific and medical communities. They play a crucial role in understanding the function and reactions in the body, as well as in researching and developing treatments for genetic diseases.

Health Conditions Related to Genetic Changes

Genetic changes in the PDHB gene, which encodes the E1beta component of the pyruvate dehydrogenase (PDH) complex, can lead to various health conditions.

This syndrome is characterized by progressive neurological deterioration, which includes developmental delay, loss of motor skills, and other neurological problems. The deficiency in the E1beta component of the PDH complex caused by genetic changes in the PDHB gene is one of the causes of Leigh syndrome.

In addition to Leigh syndrome, genetic changes in the PDHB gene can also cause other diseases and syndromes. These conditions may have different names and clinical presentations, depending on the specific variant in the PDHB gene. Some of these conditions may be listed in databases and registries for genetic disorders, such as OMIM (Online Mendelian Inheritance in Man) and GeneReviews.

Genetic testing for changes in the PDHB gene can provide valuable information for the diagnosis and management of health conditions related to such changes. These tests can detect genetic variants in the PDHB gene and may involve sequencing the gene or specific regions of it. Testing can be performed in specialized laboratories or genetic testing centers.
