Transcription factor 3 (TCF3; also known as E2A) is a gene that encodes a protein that functions in transcriptional activation by binding to regulatory E-box sequences on target genes. The protein also plays an important role in lymphopoiesis and T lymphocyte development. Fusions, missense mutations, nonsense mutations, silent mutations, frameshift deletions and insertions, and in-frame deletions are observed in cancers such as endometrial cancer, intestinal cancer, and skin cancer.

TCF3 is altered in 0.22% of all cancers with high grade ovarian serous adenocarcinoma, breast invasive ductal carcinoma, prostate adenocarcinoma, and undifferentiated pleomorphic sarcoma having the greatest prevalence of alterations [3].

TCF3 GENIE Cases - Top Diseases

The most common alterations in TCF3 are TCF3 Loss (0.17%) and TCF3 Amplification (0.03%) [3].
