EIF4A2
Overview
Eukaryotic translation initiation factor 4A2 (EIF4A2) is a gene that encodes a protein that functions as an ATP-dependent RNA helicase that plays a role in cap recognition and is required for mRNA binding to the ribosome. Fusions, missense mutations, nonsense mutations, silent mutations, frameshift deletions, and in-frame deletions are observed in cancers such as breast cancer, endometrial cancer, and skin cancer.
EIF4A2 is altered in 0.85% of all cancers with squamous cell lung carcinoma, lung adenocarcinoma, breast invasive ductal carcinoma, high grade ovarian serous adenocarcinoma, and colon adenocarcinoma having the greatest prevalence of alterations [3].
The most common alterations in EIF4A2 are EIF4A2 Amplification (0.48%), EIF4A2 Loss (0.03%), EIF4A2 M1? (0.03%), EIF4A2 E25Q (0.01%), and EIF4A2 K382N (0.01%) [3].
