The KRT12 gene provides instructions for making a protein called keratin 12, which is a member of the cytoskeletal intermediate filament family. Intermediate filaments are structural proteins that help provide strength and resilience to cells. Keratin 12 is specifically found in the cornea, the clear outer layer of the front of the eye.

Changes (variants) in the KRT12 gene are associated with various conditions, including Meesmann corneal dystrophy. Meesmann corneal dystrophy is a genetic disorder characterized by the formation of small cysts in the cornea. These cysts can cause blurred vision and sensitivity to light. In addition to Meesmann corneal dystrophy, changes in the KRT12 gene have also been found in other corneal dystrophies.

Scientists continue to study the KRT12 gene to better understand its role in corneal diseases and to develop genetic tests for these conditions. Genetic testing can help diagnose corneal dystrophies and assist in determining the best course of treatment. Additionally, databases such as OMIM and the Corneal Dystrophy Registry provide resources and references for further scientific articles and information related to the KRT12 gene and related genes.

Genetic changes in the KRT12 gene can lead to various health conditions. Some of these conditions, as listed from OMIM (Online Mendelian Inheritance in Man) and the Registry of Diseases for Kinoshita, include:

  • Corneal Dystrophy, Meesmann Type: Also known as Meesmann corneal dystrophy, this condition is characterized by the presence of cysts in the corneal epithelial cells. Mutations in the KRT12 gene can cause abnormalities in the keratin filaments, which leads to the formation of these cysts.
  • Nishida Corneal Dystrophy: This is another form of corneal dystrophy caused by genetic changes in the KRT12 gene. It is characterized by the abnormal accumulation of material in the cornea, leading to vision impairment.

For more information on these genetic changes and associated health conditions, there are several resources available. These resources include:

  1. Genetic Testing: Genetic testing can be conducted to identify specific genetic changes in the KRT12 gene. This can help diagnose individuals with corneal dystrophy or related conditions.
  2. Variant Filaments Related to the KRT12 Gene: Scientific articles and other databases provide information on variant filaments associated with the KRT12 gene and their impact on corneal health.
  3. OMIM and PubMed: OMIM and PubMed are databases that contain references to scientific articles and studies related to the KRT12 gene and its role in corneal health.
  4. Registry of Diseases for Kinoshita: This registry provides information on various corneal diseases, including those related to genetic changes in the KRT12 gene.

These resources can be valuable for understanding the genetic basis of corneal dystrophy and related conditions, as well as for further research and medical intervention.

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).

Meesmann corneal dystrophy

Meesmann corneal dystrophy is a genetic variant of corneal dystrophy that affects the epithelial layer of the cornea. It is characterized by the presence of small cysts in the epithelium, which can cause blurred vision and discomfort.

This condition is related to changes in the KRT12 gene, which codes for a protein called keratin 12. This protein is important for maintaining the structure and function of the corneal epithelium.

Meesmann corneal dystrophy is one of several related diseases that affect the cornea. Other conditions in this group include Meesmanns epithelial corneal dystrophy, which is caused by changes in other genes related to keratin production.

Testing for Meesmann corneal dystrophy can be done through genetic testing to detect changes in the KRT12 gene. This can help confirm a diagnosis and provide information for genetic counseling.

References to Meesmann corneal dystrophy can be found in scientific articles and databases such as PubMed and OMIM. The OMIM database provides additional information on this condition, including genetic changes associated with it.
