Cyclin-dependent kinase 9 (CDK9) is a gene that encodes a member of a protein complex that is an elongation factor for RNA polymerase II-directed transcription. Missense mutations, silent mutations, and frameshift insertions are observed in cancers such as colon cancer, skin cancer, and endometrial cancer.
CDK9 is altered in 0.73% of all cancers with colon adenocarcinoma, endometrial endometrioid adenocarcinoma, lung adenocarcinoma, high grade ovarian serous adenocarcinoma, and breast invasive ductal carcinoma having the greatest prevalence of alterations .
The most common alterations in CDK9 are CDK9 Mutation (0.58%), CDK9 Amplification (0.07%), CDK9 P286L (0.03%), CDK9 G326D (0.02%), and CDK9 K24R (0.02%) .
