POLH gene

Published Categorized as Genetics
POLH gene

The POLH gene, also known as rad30, is a central gene involved in DNA repair. It is listed in various genetic databases and is associated with a variant of the xeroderma pigmentosum disease, known as XP-V. XP-V is characterized by an increased sensitivity to UV radiation and a higher risk of developing skin cancers.

The POLH gene encodes a specialized DNA polymerase, which plays a critical role in copying damaged DNA. Mutations in this gene can lead to a decrease in the activity of the polymerase, impairing the repair process and increasing the risk of genetic changes.

Scientific articles and studies on the POLH gene can be found in various resources, such as PubMed and OMIM. These resources provide information on the gene’s structure, function, and associated diseases. They also offer references to other related articles and resources for further reading.

Testing for variants in the POLH gene can be useful for individuals with a family history of XP-V or related conditions. Genetic testing can help identify carriers of the variant and provide information on the risk of developing these diseases. The POLH gene is included in the central catalog of genes associated with health and diseases, making it an important target for research and testing.

Health Conditions Related to Genetic Changes

Genetic changes in the POLH gene, also known as RAD30A, have been found to be associated with several health conditions. The POLH gene codes for the protein DNA polymerase eta, which is involved in DNA repair.

  • Xeroderma pigmentosum variant (XP-V): Individuals with genetic variants in the POLH gene have an increased risk of developing XP-V, which is a rare genetic disorder characterized by extreme sensitivity to ultraviolet (UV) radiation. This condition leads to an inability to repair damaged DNA, resulting in the development of skin cancers and other conditions related to sun exposure.
  • Dermatol: Mutations in the POLH gene have also been linked to an increased risk of dermatol, a condition characterized by abnormal skin pigmentation and an increased sensitivity to UV radiation.

Testing for genetic changes in the POLH gene can be done through DNA sequencing and other additional tests. It is important for individuals with a family history of xeroderma pigmentosum or related conditions to undergo genetic testing to identify potential variants in the POLH gene.

Several scientific databases and registries, such as OMIM (Online Mendelian Inheritance in Man), centralize information on genetic changes in the POLH gene and related conditions. These resources provide references to scientific articles, catalog gene variants, and offer information on disease tolerance and variant changes.

Xeroderma pigmentosum

Xeroderma pigmentosum (XP) is a rare genetic disease characterized by an extreme sensitivity to ultraviolet (UV) radiation from sunlight. It is caused by mutations in genes involved in the nucleotide excision repair (NER) pathway, such as the POLH gene.

There are several variants of xeroderma pigmentosum, including XP-V (variant) which is caused by mutations in the POLH gene. The POLH gene provides instructions for making a protein called polymerase eta (Pol η), which is involved in DNA replication. Mutations in the POLH gene result in a deficient Pol η, impairing the DNA repair process and leading to increased sensitivity and susceptibility to UV-induced DNA damage.

Individuals with xeroderma pigmentosum-variant (XP-V) have a higher tolerance to UV radiation compared to other XP subtypes. However, they still have an increased risk of developing skin cancers and other sun-related conditions.

Scientific databases and resources such as OMIM, PubMed, and the Health and Human Services Genetic Testing Registry provide additional information related to xeroderma pigmentosum. These resources contain articles, references, testing information, and catalog of genetic changes in POLH gene and other related genes.

Central registry and databases for xeroderma pigmentosum and other related diseases can be accessed to find more comprehensive information about the condition. These resources serve as valuable references for understanding the genetic changes, testing options, and management strategies for individuals affected by xeroderma pigmentosum and its variants.

Catalog of Genes and Diseases from OMIM

The OMIM database is a comprehensive resource that provides information on genes and diseases. It serves as a central repository for scientific articles, genetic databases, and other resources related to genetic conditions.

One of the genes listed in the OMIM database is the POLH gene. This gene is also known as XP-V (xeroderma pigmentosum-variant) gene. Mutations in the POLH gene can lead to xeroderma pigmentosum, a rare genetic disorder characterized by extreme sensitivity to ultraviolet (UV) light and an increased risk of skin cancer.

Multiple variants of the POLH gene have been identified, and the OMIM database provides detailed information on these variants. The database includes references to scientific articles and databases where additional information about the gene and its variants can be found.

Testing for variants in the POLH gene can be done through genetic testing. This testing can help determine the genetic changes present in an individual’s POLH gene and assess their risk for xeroderma pigmentosum.

Individuals with xeroderma pigmentosum often have a deficiency in the POLH gene, which plays a crucial role in DNA repair. The POLH gene encodes a DNA polymerase that is involved in copying damaged DNA. Without functional POLH gene, the body’s ability to repair DNA damage caused by UV light is impaired, leading to the development of skin lesions and an increased risk of skin cancer.

The OMIM database also provides information on other genes associated with xeroderma pigmentosum and related conditions. These genes include XPA, XPC, XPD, XPF, XPG, and RAD30, each of them playing a role in DNA repair and maintenance.

In summary, the OMIM database serves as a catalog of genes and diseases, providing valuable information on the POLH gene, its variants, and related conditions such as xeroderma pigmentosum. It is a valuable resource for researchers, healthcare professionals, and individuals seeking information about genetic disorders.

Gene and Variant Databases

Gene and variant databases provide valuable resources for researching and understanding diseases and genetic variations. These databases contain extensive information on genes, variant names, related diseases, and testing resources.

One of the main databases for gene and variant information is the POLH Gene Mutation Database. This database collects and catalogs information on genetic changes in the POLH gene, which is responsible for encoding the polymerase that copies damaged DNA. Variants in this gene can lead to a condition called xeroderma pigmentosum-variant (XP-V), which is characterized by reduced tolerance to UV radiation and an increased risk of skin cancer.

The POLH Gene Mutation Database provides a central repository for scientific articles, references, and additional information on POLH gene variants. It also lists other genes and variants associated with xeroderma pigmentosum, providing a comprehensive catalog of genetic changes related to this condition.

For health professionals and researchers, these databases serve as important tools for understanding the genetic basis of diseases and for conducting genetic testing. They enable the identification of specific gene variants that can be associated with certain diseases and provide insights into the underlying mechanisms of these conditions.

Some of the other gene and variant databases include PubMed, which is a scientific literature database that provides access to a vast collection of research articles and references. The database allows for searching and retrieving information on genes and variants associated with various diseases.

In summary, gene and variant databases are essential resources for studying diseases, testing for genetic changes, and understanding the role of specific genes in various conditions. These databases provide valuable information and resources for scientists, health professionals, and researchers.
