Mutations in the human CDKN2A gene have been associated with cancer . Therefore, although it is clear CDKN2A is involved in cancer and is a marker of ageing, its mechanistic role in human ageing remains unknown. Cytogenetic information Cytogenetic band 9p21 Location CDKN2A (ARF, CDK4I, CDKN2, CMM2, INK4, INK4a, MLM, MTS1, p14, p14ARF, p16, p16INK4a, p19, p19Arf) protein expression summary.

20, 21 ). The p16 INK4a protein inhibits the CDK4–6 kinases, maintaining the Rb protein in an unphosphorylated, growth-suppressive state, arresting the cell cycle ( 20, 22 ). p19 ARF binds the double minute 2 homolog, thereby stabilizing TP53, arresting cell proliferation, or leading to apoptosis CDKN2A is part of a locus that also contains CDKN2B, which encodes p15 INK4b, a tumour suppressor that, like p16 INK4a, inhibits CDK4/CDK6 10. CDKN2A is the second most frequently inactivated tumour suppressor gene in cancer 9, 11 and its inactivation is achieved in the majority of cases via homozygous deletion or promoter hypermethylation 11. Gene name: CDKN2A (HGNC Symbol) Synonyms: ARF, CDK4I, CDKN2, CMM2, INK4, INK4a, MLM, MTS1, p14, p14ARF, p16, p16INK4a, p19, p19Arf: Description: Cyclin dependent kinase inhibitor 2A (HGNC Symbol) Chromosome: 9: Cytoband: p21.3: Chromosome location (bp) 21967753 - 21995301: Number of transcripts i CDKN2A is one of the most studied tumor suppressor genes.

Mutations in this gene are the most common cause of inherited melanoma. The risk of melanoma in CDKN2A mutation carriers is approximately 14% by age 50 years, 24% by age 70 years and 28% by age 80 years. GeneCards Summary for CDKN2A Gene.

tumours and review current data on the germ-line mutations detected to date in the CDKN2A gene, in view of the association not on ly with melanoma, but also with additional malignant diseases, such as pancreas carcinoma and breast cancer. 2. Case presentation and review of the literature 2.1 Clinical observations and management

[7] 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 is altered in 23.69% of head and neck squamous cell carcinoma patients with CDKN2A Loss present in 9.06% of all head and neck squamous cell carcinoma patients [ 4 ].

Mutations in one copy of the CDKN2A gene can increase the chance for you to develop certain types of cancer in your lifetime. Condition fammm People with a CDKN2A mutation have familial atypical multiple mole melanoma (FAMMM) syndrome.

PMID 32941720 This review describes susceptibility genes currently known to be involved in melanoma predisposition, genetic testing of familial melanoma patients, and management implications. Results: CDKN2A is the major high-penetrance susceptibility gene with germline mutations identified in 20%-40% of melanoma families. CDKN2A gene The CDKN2A gene is a regulator of cell division. Mutations in this gene are the most common cause of inherited melanoma.

Germline pathogenic variants in several other genes, including CDK4 , MITF , BAP1 , and BRCA2 , have also been found to be associated with melanoma. DB-ID: database ID of variant, grouping multiple observations of the same variant together, starting with the HGNC gene symbol, followed by an underscore (_) and a six digit number (e.g. DMD_012345). _000000 is used for variants where DNA was not analysed (change predicted from RNA analysis), variants seen in animal models or variants not seen in humans but functionally tested in vitro Background: Gene CDKN2A, which encodes for p16INK4a/p14ARF is known to be important growth suppressor gene.

In most cancers, genome stability is disturbed and pancreatic cancer is not the exception. Approximately 97% of pancreatic cancers have gene derangements, defined by point mutations, amplifications, deletions, translocations, and inversions. This review describes the most frequent genetic alterations found in pancreatic cancer.

Cdkn2a gene reviews keyword after analyzing the system lists the list of keywords related and the list of websites with related content, in addition you can see which keywords most interested customers on the this website Germline mutations in CDKN2A are associated with an increased susceptibility to develop skin cancer. Hypermethylation of tumor suppressor genes has been implicated in various cancers. In 2013, a meta-analysis revealed an increased frequency of DNA methylation of the p16 gene in esophageal cancer. This gene generates several transcript variants which differ in their first exons. At least three alternatively spliced variants encoding distinct proteins have been reported, two of which encode structurally related isoforms known to function as inhibitors of CDK4 kinase.

Aberrant gene silencing is highly associated with altered cell cycle regulation during carcinogenesis. In particular, silencing of the CDKN2A tumor suppressor gene, which encodes the p16INK4a protein, has a causal link with several different types of cancers. The p16INK4a protein plays an executional role in cell cycle and senescence through the regulation of the cyclin-dependent kinase (CDK
