Interferon regulatory factor 4 (IRF4) is a gene that encodes a transcription factor protein that functions as a regulator of interferons and interferon-inducible genes. The protein is also a negative regulator of Toll-like-receptor (TLR) signaling. Fusions, missense mutations, nonsense mutations, and silent mutations are observed in cancers such as hematopoietic and lymphoid cancers, intestinal cancer, and ovarian cancer.

IRF4 is altered in 0.38% of all cancers with cutaneous melanoma, prostate adenocarcinoma, breast invasive ductal carcinoma, high grade ovarian serous adenocarcinoma, and lung adenocarcinoma having the greatest prevalence of alterations [3].

The most common alterations in IRF4 are IRF4 Loss (0.16%) and IRF4 Amplification (0.12%) [3].
