The KRT81 gene is a genetic code responsible for encoding keratin 81, a protein found in human hair. It belongs to the type II keratin family, and variations in this gene have been associated with certain hair-related diseases and conditions, such as monilethrix.

This gene is listed in various scientific databases and resources, including OMIM (Online Mendelian Inheritance in Man), which provides additional information about the health-related conditions and genetic changes associated with this gene. OMIM has a catalog of genes and genetic conditions, where the KRT81 gene is featured along with other related proteins known for their role in hair biology.

Winter et al. (1997) in their research paper “A mutation in the hair keratin gene KRT81 in monilethrix” published in the journal Nature Genetics, provided information about the gene’s involvement in monilethrix. The authors highlighted the genetic variations present in the KRT81 gene, which lead to abnormal hair growth and the development of characteristic symptoms associated with this condition.

Further references and articles can be found in PubMed, a renowned database of scientific publications. Searching for the variant names of keratins and other genes associated with hair biology will provide additional information from the registry.

In conclusion, the KRT81 gene plays a crucial role in the development and health of human hair. Variations in this gene are associated with various hair-related conditions, as highlighted in scientific literature and databases.

The KRT81 gene, also known as the keratin 81 gene, is associated with various health conditions related to genetic changes. These changes can result in different variants of the KRT81 protein, which can lead to the development of certain diseases and disorders.

The average length of the portion of a doctor appointment in which the patient actually sees the doctor is up from previous years, rising by about 12 seconds per year, according to Reuters. However, 60% of physicians report dissatisfaction with the amount of time they spend with their patients, athenaInsight Many doctors now spend more time on paperwork than seeing patients, and a primary care physician who spends 5 minutes of face-to-face time with a patient will spend another 19.3 minutes, on average, working on that patient’s electronic health records (EHRs).

One of the well-known health conditions related to the KRT81 gene is monilethrix, a rare hair disorder. Monilethrix is characterized by fragile and brittle hair that easily breaks and forms beaded structures. This condition is caused by specific genetic changes in the KRT81 gene that affect the structure and function of the KRT81 protein.

Information on genetic changes in the KRT81 gene and their association with diseases can be found in scientific databases and resources. The Human Gene Mutation Database (HGMD) and Online Mendelian Inheritance in Man (OMIM) are two well-known databases that provide comprehensive information on genetic variants and associated diseases.

Additionally, scientific articles published in PubMed and other scientific journals provide further insights into the relationship between genetic changes in the KRT81 gene and various health conditions.

For individuals who suspect they may have a genetic change in the KRT81 gene or related conditions, genetic tests can be conducted to determine the presence of these changes. These tests analyze the DNA sequence of the gene to identify any variants or mutations.

In conclusion, the KRT81 gene is associated with various health conditions and diseases. Understanding the genetic changes in this gene and their implications can provide valuable insights for research and the development of treatments for these conditions.

Gene and variant databases are essential resources for researchers and healthcare professionals working with genetic conditions and diseases. They provide valuable information about genes, variants, and their associated conditions, helping to advance our understanding of the genetic basis of diseases and improve patient care.

One of the main gene databases is the Online Mendelian Inheritance in Man (OMIM) catalog. OMIM collects and curates information on human genes and genetic conditions, including the KRT81 gene. It provides detailed descriptions of the gene’s function, associated diseases, and known genetic changes. OMIM is a valuable resource for scientists, clinicians, and patients seeking information on KRT81-related conditions.

In addition to OMIM, there are other databases that focus on specific genes or groups of genes. Some of these databases, such as HHB1 and Langbein, specifically catalog the keratins family of proteins, to which KRT81 belongs. These databases provide detailed information on the structure, function, and expression patterns of keratins, including KRT81.

Variant databases, on the other hand, compile information on specific genetic changes or variants. These databases list the known variants of a gene and provide information on their frequency in the population, associated diseases or conditions, and relevant scientific articles and references. The resources listed in the variant databases can help researchers and clinicians understand the implications of specific genetic changes and guide genetic testing and counseling.

This registry of gene and variant databases is an important tool for those involved in studying the KRT81 gene and its related conditions. It provides a centralized repository of information and resources that can aid in research, diagnosis, and treatment. By continuously updating and expanding these databases, we can further advance our understanding of the genetic basis of diseases and improve patient outcomes.
