CDKN2A gene mutations involved in cancer impair production of functional p16(INK4a) or, less commonly, p14(ARF), which can result in uncontrolled cell growth and tumor formation. The CDKN2A gene provides instructions for making several proteins. The most well-studied are the p16(INK4a) and the p14(ARF) proteins.

[6] The gene codes for two proteins , including the INK4 family member p16 (or p16INK4a) and p14arf . [7] CDKN2A gene mutations involved in cancer impair production of functional p16(INK4A) or, less commonly, p14(ARF), which can result in uncontrolled cell growth and tumor formation. Somatic CDKN2A gene mutations have been found in some people with brain tumors and in children with a blood cancer called acute lymphoblastic leukemia. The Cyclin-dependent kinase inhibitor 2A (CDKN2A) gene encodes several protein isoforms that function as inhibitors of CDK4 and ARF. Missense mutations, nonsense mutations, silent mutations, in-frame deletions, frameshift deletions and insertions, and whole gene deletions are observed in cancer such as cancers of the genital tract, mesothelioma, ovarian cancer, skin cancer, and multiple other cancer types. CDKN2A (Cyclin Dependent Kinase Inhibitor 2A) is a Protein Coding gene.

Mutations in CDKN2A (p16INK4a) is associated with a syndrome sometimes called Familial Atypical Mole/ Multiple Melanoma (FAMMM) + Pancreatic Cancer. Mutations in CDKN2A (p14ARF) can increase the risk for melanoma. 9102. Background: Gene CDKN2A, which encodes for p16INK4a/p14ARF is known to be important growth suppressor gene.

mutation eller. En avgörande gen kan vara CDKN2A, som sitter på kromosom 9. där den förändrade genen har hittats är det dock i de allra flesta fall exakt samma mutation. CDKN2A deletions also occur, which are rarely present in primaries.

Cancerrisken kraftigt förhöjd hos familjer med viss mutation i familjer med ärftligt melanom som har en nedärvd mutation i genen CDKN2A.

Condition fammm People with a CDKN2A mutation have familial atypical multiple mole melanoma (FAMMM) syndrome. It is known that mutations in the CDKN2A gene can affect the formation of two different types of proteins. CDKN2A (p16INK4a) mutations can cause a high risk for pancreatic cancer as well as melanoma. It is possible that this risk for pancreatic cancer also applies to some people with mutations in CDKN2A (p14ARF) or CDK4 .

Cdkn2a gene

People with MCS have a high risk for melanoma. These melanomas often occur at young ages, and it is not unusual for a person with MCS to develop melanoma two or more times during their lifetime. 1997-01-01 · CDKN2A, the gene encoding the cell-cycle inhibitor p16 CDKN2A, was first identified in 1994. Since then, somatic mutations have been observed in many cancers and germline alterations have been found in kindreds with familial atypical multiple mole/melanoma (FAMMM), also known as atypical mole syndrome. Gene Description. CDKN2A, cyclin-dependent kinase inhibitor 2A, is a tumor suppressor ( PMID: 30562755) that encodes p16 and p14ARF from alternate reading frames, which function to inhibit Cdk4 and Cdk6 and regulate Tp53 activity to promote cell-cycle arrest ( PMID: 23875803, PMID: 17055429, PMID: 27428416 ).

Gene Description.

Our study suggests that CDKN2A as a malignant gliomas suppressor gene, appears to be useful for predicting behaviour of high-grade malignant gliomas. As reported data on CDKN2A alterations in childhood ALL are discrepant, it remains important to reveal the role of this gene in cancer development.

Cdkn2a gene






The CDKN2A gene encodes different transcripts involved mostly in cell cycle regulation and cellular senescence, including the tumour suppressor proteins p16 and p19 . At least three alternatively spliced variants encoding distinct proteins have been reported.
