Subsequently, a comprehensive genomic analysis of more than 260 pediatric and young adult T-ALL patients classified these patients into eight major groups based on the translocated gene and its dysregulated expression, including TLX1, TLX3, TAL1, TAL2, LMO1/2, NKX2-1, HOXA, and LMO2-LYL1 [58]. Here, TAL1 is linked to acute lymphoblastic leukemia.
