Case presentation and review of the literature 2.1 Clinical observations and management 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.

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. 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.

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. 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.

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. The major germline tumor suppressor gene associated with melanoma is CDKN2A; pathogenic variants in CDKN2A have been estimated to account for 35% to 40% of all familial melanomas.

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.

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.

TCGA data also showed the loss of CDKN2A and CDKN2B significantly associated with recurrence in head and neck cancer patients. Conclusion: CDKN2A and CDKN2B expression analysis can be used as the prognostic marker for the oral cancer Direct sequencing of the amplified CDKN2A gene showed no somatic mutations in the 17 tumors examined. The authors concluded that enhanced expression, rather than inactivation of the CDKN2A gene, may be involved in the early stages of the pathogenesis of primary colorectal carcinomas.
