The KRIT1 gene, also known as CCM1, is an important gene associated with cerebral cavernous malformation (CCM), a genetic disorder characterized by the formation of abnormal blood vessels in the brain. CCM is a rare condition that affects approximately 1 in 100,000 people.

Scientific research on the KRIT1 gene has contributed to our understanding of the molecular mechanisms underlying this disease. The KRIT1 gene encodes a protein that interacts with other proteins involved in the regulation of blood vessel development and function.

Changes in the KRIT1 gene have been found in individuals with cerebral cavernous malformation, and testing for these changes can help diagnose the condition. In addition, genetic testing for the KRIT1 gene can provide important information for individuals and families affected by this disease, including information on inheritance patterns and risk assessment.

Several resources are available for further information on the KRIT1 gene and cerebral cavernous malformation. Databases such as OMIM and PubMed provide access to scientific articles and other relevant information on this gene and related diseases. The CCM Genetic Testing Registry, created by Labauge et al., lists additional resources and testing options for this condition.

Genetic changes in the KRIT1 gene have been associated with various health conditions. These genetic changes can lead to the development of certain diseases and disorders. Here are some health conditions related to genetic changes:

  • Cerebral Cavernous Malformation (CCM1): Variants in the KRIT1 gene have been identified as a cause of CCM1, a vascular disorder characterized by abnormal blood vessels in the brain. These changes in the KRIT1 gene result in the formation of cavernous malformations, which can cause seizures, headaches, and other neurological symptoms.
  • RHOA-GTPase gene: The KRIT1 gene interacts with the RHOA-GTPase gene, and changes in either gene can contribute to the development of cerebral cavernous malformations. The RHOA-GTPase gene is involved in regulating the shape of blood vessels and maintaining their integrity.
  • Other related genes: In addition to the KRIT1 gene, other genes such as CCM2 and PDCD10 have also been associated with cerebral cavernous malformations. Changes in these genes can disrupt the normal functioning of proteins involved in blood vessel development and maintenance.
  • Additional health conditions: Genetic changes in the KRIT1 gene have also been linked to other health conditions, including certain forms of cancer and cardiovascular disorders. These changes can impact various biological processes and signaling pathways, leading to the development of different diseases.

To learn more about the specific health conditions related to genetic changes in the KRIT1 gene, you can explore scientific databases such as PubMed and OMIM. These resources provide information on the genetic basis of diseases and conditions, as well as references to relevant articles and studies.

If you suspect that you or someone you know may have a genetic change in the KRIT1 gene or other related genes, it is recommended to consult with a healthcare professional or genetic counselor. Genetic testing can help confirm the presence of these changes and provide valuable information for diagnosis, treatment, and management of associated health conditions.

Cerebral cavernous malformation

Cerebral cavernous malformation (CCM) is a genetic disease characterized by changes in the KRIT1 gene. The KRIT1 gene, also known as CCM1, is one of the three genes associated with CCM. This disorder is listed as OMIM number 116860 in the OMIM database.

The other two genes associated with cerebral cavernous malformation are CCM2 (also known as MGC4607 or OSM), and CCM3 (also known as PDCD10 or TFAR15). The scientific names for these genes can be found in the Catalog of Genes and Diseases.

CCM1 is involved in the formation and maintenance of blood vessels in the brain. Mutations in the KRIT1 gene can lead to the development of abnormal blood vessels known as cavernous malformations. These malformations can cause health problems such as seizures, headaches, and other neurological conditions.

Studies have shown that changes in RhoA-GTPase pathway signaling play a role in the development of cerebral cavernous malformation. The complex interactions between the proteins encoded by the CCM genes and other signaling molecules are still being investigated.

The diagnosis of cerebral cavernous malformation can be confirmed through genetic testing. This involves analyzing the KRIT1 gene and the other CCM genes for any changes or variants. The Cerebral Cavernous Malformation Clinical Registry provides additional information on testing and related conditions.
