Li et al.32 performed genome sequencing on pre-treatment and post-treatment samples from 82 pediatric T-ALL patients, and found that mutations in IL-7R signaling pathway genes including JAK1, KRAS, IL-7R, JAK3, NF1, NRAS, and Akt were associated with both GC resistance and poor outcomes. The gene discussed is NRAS; the disease is acute lymphoblastic leukemia.
