The candidate genes observed in the B-ALL cases were ABCC6, BCNP1, BMP6, BRAT1, BRCA1, DNHD, ETAA1, ETV6, JAK2, JAK3, KSR1, MAP2K2, MLLT10, MUTYH, MYH11, MVP, PAPSS2, RAD52, RECQL, TGFBRS1, TP53, and WRN. The candidate genes observed in the T-ALL cases were ATR, BRCA2, BIRC6, and NOTCH1, and those observed in lymphoma cases were MLH1, MSH6, RAD52, and TNFRSF9 (Figure 3). The gene discussed is MAP2K2; the disease is precursor B-cell acute lymphoblastic leukemia.
