Signal transducer and activator of transcription 4 (STAT4) is a gene that encodes a transcription factor protein that mediates responses to IL12 in lymphocytes and regulates the differentiation of helper T-cells. Missense mutations, nonsense mutations, silent mutations, frameshift deletions, and in-frame deletions are observed in cancers such as endometrial cancer, intestinal cancer, and skin cancer.

STAT4 is altered in 1.04% of all cancers with cutaneous melanoma having the greatest prevalence of alterations [3].
