Cyclin-dependent kinase inhibitor 2C (CDKN2C, also known as p18) is a gene that encodes a protein that inhibits the activation of CDK 4 and CDK6. Missense mutations, nonsense mutations, silent mutations, and frameshift deletions and insertions are observed in cancers such as bone cancer, endometrial cancer, and intestinal cancer.

CDKN2C is altered in 0.71% of all cancers with conventional glioblastoma multiforme, lung adenocarcinoma, glioblastoma, colon adenocarcinoma, and endometrial endometrioid adenocarcinoma having the greatest prevalence of alterations [3].

The most common alterations in CDKN2C are CDKN2C Mutation (0.35%), CDKN2C Loss (0.23%), CDKN2C Amplification (0.12%), CDKN2C Nonsense (0.04%), and CDKN2C Fusion (0.01%) [3].
