DLEU7 (Deleted in Lymphocytic Leukaemia 7) is a gene identified for its potential role in cancer biology, particularly in chronic lymphocytic leukaemia (CLL). It is believed to influence key processes such as cell cycle control and programmed cell death (apoptosis). Loss or malfunction of DLEU7 may contribute to cancer development and progression, making it a focus of research for new diagnostic markers and targeted therapies.
