IKZF1 (IKAROS Family Zinc Finger 1): IKZF1 is a gene that encodes a zinc finger transcription factor essential for immune cell development and differentiation, particularly in B cells. Mutations in IKZF1 are common in B-cell acute lymphoblastic leukemia (B-ALL), underscoring its key role in hematopoiesis and immune regulation. Its interactions with other genes and its role in maintaining immune balance make it a focus of research in both immunology and oncology.
