They demonstrated that BCL2-antagonist/killer 1 (BAK1), cyclin-dependent kinase inhibitor 2 C (CDKN2C), glutathione S-transferase M 1 (GSTM1) and MT-IF formed a gene set that differed between ALL patients at diagnosis who had a risk of relapse and those who did not [24]. The gene discussed is GSTM1; the disease is acute lymphoblastic leukemia.
