Here, we explored the IL7R and SH2B3 expression in adult ALL and found that IL7R is significantly higher and Sh2B3 lower expressed in B-ALL compared to normal bone marrow control, and the IL7RhighSH2B3low is associated with high-risk factors, and with high relapse rate and low disease-free survival rate in the patients. The gene discussed is IL7R; the disease is acute lymphoblastic leukemia.
