We validated the classification ability of these markers in an independent cohort of Danish patients with ALL and found that a subset of these 14 markers (EBF1, VPREB3, LINC00114, ENSG00000227706, CCN2, and NDST3) could perfectly separate B‐ and T‐ALL in this independent cohort (Fig. 8). The gene discussed is EBF1; the disease is acute lymphoblastic leukemia.
