CDKN2A, also known as cyclin-dependent kinase Inhibitor 2A, is a gene on chromosome 9. The gene codes for two proteins, both acting as tumor suppressors.

Somatic mutations of CDKN2A are common in the majority of human cancers, with estimates that CDKN2a is the second most commonly inactivated gene in cancerous tissues after p53. Germline mutations of CDKN2A are associated with familial melanoma, glioblastoma and pancreatic cancer.Wikipedia

The degree to which risk for melanoma is increased due to a CDKN2A mutation considered pathogenic is unclear. As stated in [PMID 20831418OA-icon.png], published penetrance estimates through age 80 for CDKN2A mutations range as high as 67% [PMID 12072543OA-icon.png]. Researchers in the GEM Study estimated the risk for melanoma among CDKN2A mutation carriers to be 28% through age 80 [PMID 16234564OA-icon.png]. The authors of the previously cited paper ultimately settled on telling participants in their study that CDKN2A mutations conferred an overall 30–65% risk for melanoma by age 80 and could also increase the risk of a new primary melanoma.
