Cyclin E1 (CCNE1) is a gene that encodes a protein that is a member of the cyclin family. The protein complexes with and functions as a regulator of CDK2. The activity of this protein complex is required for cell cycle G1/S transition. Missense mutations, silent mutations, and frameshift deletions are observed in cancers such as intestinal cancer, lung cancer, and stomach cancer.

CCNE1 is altered in 2.15% of all cancers with lung adenocarcinoma, high grade ovarian serous adenocarcinoma, breast invasive ductal carcinoma, colon adenocarcinoma, and esophageal adenocarcinoma having the greatest prevalence of alterations [3].

CCNE1 GENIE Cases - Top Diseases

The most common alterations in CCNE1 are CCNE1 Amplification (1.87%), CCNE1 Mutation (0.52%), CCNE1 Loss (0.05%), CCNE1 Fusion (0.05%), and CCNE1 A214V (0.04%) [3].
