We identified Lmo2, a T-cell-associated oncogene20, in several independent samples (No. 1, 3, and 5) and also detected leukemia-associated genes, such as Fli1 (Friend leukemia virus-induced erythroleukemia-1) and Mecom (Mds1 and Evi1 complex locus, also known as Evi1)21, 22. The gene discussed is RUNX1; the disease is leukemia.
