DLEU7 (Deleted in Lymphocytic Leukemia 7) is a gene recognized for its potential role in cancer biology, especially in chronic lymphocytic leukemia (CLL). It is thought to affect key processes such as cell cycle regulation and programmed cell death (apoptosis). Loss or dysfunction of DLEU7 may contribute to cancer development and progression, making it a key focus in research for new diagnostic markers and targeted therapies.
